Dude. No kidding. Exactly why I didn’t wanna tow mine. Knew something easy was up. Something electrical. Finally found a video that mentioned this wire and sure enough, mice chewed it.

Mechanics are runing out of customers sitting in the office ughh not today not busy probably tomorrow when I am Working on my garage watching this good guy thanks men
2003 Tahoe Z71 here, purchased new, over 300,000 miles and periodic wonky electronics, like low power mode and the ABS and Traction Control lights and weird DTC codes; also electric lock and window problems. I feel your pain, but I have learned the hard way about Chevys and bad grounds from another Chevy I own, and keep an extra braided ground strap on hand at all times, and use my digital voltmeters to check my circuits. The best thing I have learned is to buy no new parts until I check battery voltage and battery ground from negative battery post to engine block then negative post to chassis/frame if it's a no crank/no start. A bad battery connector can always keep it from starting or recharging correctly, so check the connection or voltage drop between the negative battery post and the wire leaving the negative connector or to the attachment point of the negative cable to the frame and/or engine block. For starts resulting low power mode, traction control and/or ABS lights, unplug the accelerator pedal position sensor connector, then spray both male and female parts of the connection with De-Oxit D5 or some similar electronic contact cleaner, even just 99% rubbing alcohol in a small pump sprayer, and plug the connector back in. If that doesn't work, do the same to the throttle body connector, and visually check and spray the connectors to the fuel pump control module and/or pump and/or pump relay. Check and spray any electrical connector exposed to vibration, flexing or weather or that has to work perfectly for the vehicle to function. For lasting connector protection from corrosion, use silicone di-electric grease. If you had gotten an inexpensive scan tool ($30), or a blue tooth type scanner that uses a phone app to give you the diagnostic news ($80 to $100), you would have saved big bucks and a couple of day's lost time in this situation. Scotty Kilmer has current recommendations for these on his channel. Also, ask your insurance agent about the cost of roadside assistance/towing on your policy - could be about as little as 10 to $20 a year per vehicle, which is what I pay. If your policy already has it, or if you are a member of an auto club, you might be able to get reimbursed for all or part of the towing bill.
I’ve been watching videos all over CZcams for a week now and have been trying everything for the past week. I ended up ordering an ECM tonight and then ran across your video so I ran outside and sure enough the same ground wire was broken. I fixed it in the damn thing fired right up. Needless to say I’m trying to cancel my order now😂 You are a life saver I appreciate it so much ! I replaced my ignition my key Tumblr the battery and starter before all of this!
Any description of what to move and see that wire? My suv turns off at times and all of a sudden turns on in a couple minutes need help locating that wire?
Bro thank you for this video, today my wife calls me said the car just shut off while she was driving. So I'm at work I'm a heavy equipment mechanic, an I run a service truck, so I pack up haul but over to her cause it's a 100 degree out here in Texas, an she got my kiddos with her. So I pull up start checking fuses an battery normal diagnosis stuff, load tested batter an it was bad went an swapped out battery, still no start. Finally I called my roadside assistance, so I could just tow the car to the house to get them out of the heat, an work on it there. So as I'm waiting on tow truck to arrive , I start scrolling through no start issue on CZcams for suburban, an bam land on your vid. Get back out of the truck to look at the suburban, an same thing wire broken off at the back, so I hook my my test leads back to ground right quick, an she fires right up!!! Right as the tow truck is pulling up, so I called off the tow an saved$ 135, just put a new terminal end on the ground wire an hooked it back up, no problems out of it so far. All praise be to God, for me finding this video , an you making it.
Thank you for putting this video out. I have a 05 Tahoe with the same problem. I cut the wire you showed (mine was not broke), and grounded it like you showed. Mine would not even turn over. It runs now and hopefully this will solve my problem. I bought it in may 2019 and I have driven it a total of 3 months because of this and reduced engine power. It has sit since October because I couldn’t afford to fix it because of me having surgery. Now it runs so thank you again.
the problem my truck has is it wont crank or turn over. i tried eveything and put new parts in. my ground wire like the one in the video is not broken but should i still cut it and reground it?
Sir, I sure do thank you. Your my favorite person right now. My 05 Tahoe did the same thing and I seen your video, ran outside and the same wire was not connected. I messed with it for close to 2 weeks lol. Thanks for your video.
video just saved me alot of stress and time, did a engine swap in a 07 silverado and this ground was bad got her grounded and finally turning over thanks for sharing buddy
A tip from someone that used to work in auto parts (me) dont trust them when the tester says the battery is bad. A lot of times when the battery is all the dead the tester will say "replace battery." Instead of buying a battery tell them you want the battery charged. You will need an overnight slow charge to get it back right. They have a quick 1 hr charge but sometimes the tester will say replace battery after those also.
This guys on this type of shop's are parts changers, not a mechanics, I cant believe they didn't make a full voltage diagnostic before they iven start changing parts, is hard to find a good reliable and honest mechanic, Thanks for the video, we have to learn from you experience.
Thank you. for creating and sharing this video. The Same thing happened to my 2005 Chevy avalanche. I’m glad I found this video. It’s save me a lot of time, or money.
Omg bro you have no idea how happy I am I found this video, 2 years I've Been having issues with my truck and meals and mechanics couldn't figure it out. It's been sitting for a good part of those 2 years and I found that ground that didn't have a good connection to the post. Rewired it and connected it and bam runs like a dream! You're a life saver!
Awesome Thanks man!! My 04 Tahoe put me down too just yesterday. Stalled and making loud noises and my first thought was there goes my engine. Scared me. I wasn’t even finished watching your video but as soon as I seen where the wires were and that’s exactly what it was. So again appreciate your help!!
Because a lot of people think of mechanics as just parts swappers without realizing that sometimes it’s a diagnostic roller coaster just to find out what part is wrong.
Most people are parts changers not mechanics. Diagnosis is key finding the issue then fixing it the right way. Throwing parts at stuff is a costly lazy way to try and fix anything.
Thanks! This video led me in the right direction. My issue was with the ground that goes from the firewall to the back of the block. This was my fix. I bought the same oe ground wire and ran it from the firewall bolt to one of the alternator bolts.
This video saved my ass and a ton of money, time and frustration. Same exact issue in 2004 Yukon. Found that wire and sure enough, touched it and it broke off. Connected it to ground and bingo all is good.Thank you for sharing.
FIRST THING. Pep Boys policy, if you can't figure it out and give the customer a definite answer as to what the problem is the customer does not get charged. They owe you a full refund. Just call 1-800 or 1-888-pep-boys. Trust me it works. I'm a retired master tech and have repaired that issue countless times. Good catch brother. Make sure you have a wire going from firewall to back of cylinder head. Very important.
I checked that wire, it was firm but I cut it anyways. I found an inch long break exposing the wire so I soldered a new wire, used heat shrink to cover 6 inches of it, grounded to the forewall, cleaned the grounds under the driver door to frame. Cleared the codes and so far so good. I just wanted to say thanks because the manual doesn't say real world things and I work long hours and don't have time to keep throwing parts and chasing a unicorn problem. Thanks.
I love how you say "I've been dealin with..." I HATE GMT-800's now.... I miss my '97. All the BULLSHIT modules they've added and not been able to keep up with...these things are complete roulette. . Yeah the ground wire. ....stupid. I'm so disappointed with my '02. Thank you..... Dude. This has happened SO many times. Thank you.
Use the big 3 method from car audio!! Put a ground grom battery to body, battery to engine mount, and if possible battery and engine to frame! Make sure to clean connect area to clean bare metal! You should also add a bigger wire to battery to alternator for better charging, be sure to run through the current sensing ring of electric system!! I had to do this on my chevy power wire to make electric system to function correctly!! I had to splice a second ring sensor to original for running extra zero guage for audio power! It solved my problem of shutting off ac after a few minutes and other charging issues!! Good luck
Yes,I"m an electrician by trade & sometimes the problem is very simple if you have a multimeter to.test the voltage with,on my Chevrolet LS1 V8 engine in my car,when I was replacing the hydraulic lifters in 2018 & I refitted the cylinder heads I missed fitting a couple of earth leads connections onto the back of the left hand cylinder head & a "contact dealer" message came up on the instrument.panel which usually means PCM failure. On the left hand side of the car there's a positive power supply for the ignition coils integrated in with the air conditioning pressure switch wiring loom so that needed to be connected before the engine would even start as that wasn't connected either & the engine wouldn't start !
Thanks for video, been working on 2004 silverado, no crank no start, dash lights staying, replaced ignition switch still nothing frickin going crazy trying to figure it out. Watched this went straight to wire it was just hanging like you said fixed ground problem started first try.
Mitch and Son in Law Will Drake. 2004 chevy 3500 dually. Just replaced both knock sensors underneath the intake plenum. Had to remove the plenum and to do so we unhooked all 8 plugs to injectors and had to tie the harness on the passenger side up and back towards corner of firewall and fender. Made removing the plenum very easy. Got knock sensors changed and plenum back on. hooked up all injectors and other plugs etc. Got in and turned key on and all dash lights went crazy. Right away I new something wasn't right in Denmark. Turned key to start position and lights went out then back on and went all funky but no crank . Turned key off but all lights stayed on. removed key and different lights blinked on and off then stayed on with key out. Had to remove battery cable to shut dash down.. My son in law started googling and found your video. He checked and sure enough that wire was broke and hanging behind firewall. While pulling on harness and tying it back we had broke the wire where it was grounded to firewall. reconnected the wire to ground exactly where you did and the damned truck started on first crank. You are a God send and thank you so much. Hope your video helps many others also.
This video is a perfect example of why we, as diagnostic techs are in business. It has nothing to do with it being a Chevy. It has to do with competent diagnostic ability and knowing how to perform proper repairs. Good for you getting it running, but have a professional fix that ground the right way.
dawg i love you rite now my brother. i spent all kinda money on this dam truck watched all kinda video. got up this am watched your video did what u did an i be dam. thank my brother
also theres a ground strap under the truck that wreaks havoc as well leading edge of drivers door follow it straight down under vehicle to frame of the vehicle its alongside your throttle cable remove ground clean all surfaces well (sandpaper ,scotchbrite or a good wire brush) replace ground to original position and your good , this ground can cause the reduced engine power fault
Now you need to put in better quality ground wires; understand that there are several on all vehicles. Make sure that the attach points of all the wires are clean and use dielectric grease on the connections. Good luck Sir!
The fuel pump cutting on when this happened? Im having the same problem but i jumped the starter and not getting spark and the fuel pump isnt turning on when i turn the key on
Tell me about it! Same thing happened to me. Except, I took it to Chevrolet. I have a 2003 GMC Yukon SLT 4WD. I told them I thought it was the ground wire. They said they would look at it. They said it was the ground wire, but that they had to take all these assorted parts off the vehicle to access it. Charged me $400 something. I personally think its a set up - scam by Chevrolet. It happens to a lot of vehicles. Should be classified as a defective part issue and there should be no charge for the fix.
The ground point back there is a major issue,, that ground has a few different wires on it. Within a year your truck is not going to start again but this time another wire is going to break free from that ground point. That ground is for the ECM and a easy fix is to take one screw out of the engine computer and put a wire on the screw and run it to battery ground. 👌
I would recommend using a thicker gauge ground wire when hooking up to your existing ground wire. Two ways you can connect it. You can use "Scotch Lock" connectors, these take the hassle out of soldering. Then use shrink tube followed by a plastic wire guard. Or you can just solder the existing wire with shrink tube. I preferre scotch locks.
I pulled wrenches for 15 years, ASE certificates in 7 of the 8 areas at the time. I got out due to the need to obtain training that employers either did not want to help with or you got their brainwashing blurb school. One thing I remember printed on the side of every Sun Oscilloscope was "Test not guess". I have lived by that since I saw it. I have been in Industrial Electrical Maintenance for over 30 years. Finding issues like this is an almost daily occurance in a variety of settings.
OK happened to my son making pickup at airport 2 hours away....Somehow got jump and got things going again....watched several videos (2004 Crew Cab Chevy 5.3) and pulled on the wire seemed tight....next morning transmission indicator leds were flashing, Jumped, and has run with all gages working again for several short trips around town...Perhaps just got enough corrosion lose to get it to ground again.....our wire was Black with white stripe.
Buddies dodge ram had a similar problem. Dealer accused him of modifications (none). After 4 months of back/forth, they FLEW in their Master Tech, Fixed after a hour. Samething i was taught. Always check your grounds first.
Mines have over fueling issues and i put a new fuel pump and filter in it and a MAF sensor and it still does it coule a bad ground cause the over fueling and the pcm to read running lean ?
Seems like that geneeration, '99-'06, Chevy/GM's with those Vortec engines, have an issue with grounds failing. I recall some dude has great vids on that specific problem and how to remedy it. Big Three, etc., etc., etc., but more importantly, how to correct that lurking issue.
I have mine running to that same ground that goes to the hood also. The original spot had oil on it my cluster still isn’t working though. Hasn’t stalled on me yet 🤞 hope that doesn’t happen.
question i Have a 2000 chevy suburban 5.3 engine i been researching for the past few hours couldnt understand so is the two ground black wires with the white stripes hooked up to the back of engine block cut and then hooked up to one single wire ??? i would appretiate the response
report7777 it May chatter n sound as if you have engine damage, sputter uphills, headlight may flicker, hitting large bump may change drivability temporarily.
The grd wire looks like at #10 so a similar would be well devised. Better to over size then under. Depending on your area , any grds which I do/ redo I use Kopper Kote it lasts longer the the other has more oil to keep that area from rusting sooooner. Don't like doing jobs twice.
question. the problem i have is my tahoe wont crank or turn over. i tried everything i could think of and replaced alot of parts. could that ground wire in the video be my problem? i checked it out its not broken i tugged on it but should i try to cut it and re ground it?
Did they tow your truck on a flatbed truck? because rolling the trucks wheels, front or back, will burn up your 2nd or third gear depending on the average speed the tow truck. Happened to me!
Man you might of just saved me from selling my truck, I thought I had a short in the column but mine is doing the same thing and I swap three trans out and now that I think of it I never hooked the ground back up I don't think.
Mine is a lil uderpowered though new by about 45 CCA's . Sounding rough when it used to start . Just got it out of shop . I hope I didn't damage starter or anything else . 2016 Ford Focus SE 2.0L
Haven't had one yet fail me every gm Chevy I had grounds are bad but everything else makes me keep buying them once you learn everything your unstoppable long live gm Chevy
Dude. No kidding. Exactly why I didn’t wanna tow mine. Knew something easy was up. Something electrical. Finally found a video that mentioned this wire and sure enough, mice chewed it.

Thanks brother, my boy bern having issue and about to spend a nut, you saved him brother. You paid it forward. You got great karma..
Thanks for posting this my 03 has been worked on for roughly a year and it turned out to be that ground wire broke
This video saved my ass and a ton of money, time and frustration. Same exact issue in 2004 Yukon. Found that wire and sure enough, touched it and it broke off. Connected it to ground and bingo all is good.Thank you for sharing.
Thanks Ivan for the great tip , im gonna upgrade my ground wires on my 03 Silverado.

Make sure you have a wire going from firewall to back of cylinder head. Very important.
I checked that wire, it was firm but I cut it anyways. I found an inch long break exposing the wire so I soldered a new wire, used heat shrink to cover 6 inches of it, grounded to the forewall, cleaned the grounds under the driver door to frame. Cleared the codes and so far so good. I just wanted to say thanks because the manual doesn't say real world things and I work long hours and don't have time to keep throwing parts and chasing a unicorn problem. Thanks.
Early Christmas Gift for my 2005 Silverado , Thx !!!!
I love how you say "I've been dealin with..." I HATE GMT-800's now.... I miss my '97. All the BULLSHIT modules they've added and not been able to keep up with...these things are complete roulette. . Yeah the ground wire. ....stupid. I'm so disappointed with my '02.
Thank you..... Dude. This has happened SO many times. Thank you.
Use the big 3 method from car audio!! Put a ground grom battery to body, battery to engine mount, and if possible battery and engine to frame! Make sure to clean connect area to clean bare metal! You should also add a bigger wire to battery to alternator for better charging, be sure to run through the current sensing ring of electric system!! I had to do this on my chevy power wire to make electric system to function correctly!! I had to splice a second ring sensor to original for running extra zero guage for audio power! It solved my problem of shutting off ac after a few minutes and other charging issues!! Good luck
Sounds like y'all trying to explain yourself after getting pulled over to the cops LOL. But seriously thanks
Yes,I"m an electrician by trade & sometimes the problem is very simple if you have a multimeter to.test the voltage with,on my Chevrolet LS1 V8 engine in my car,when I was replacing the hydraulic lifters in 2018 & I refitted the cylinder heads I missed fitting a couple of earth leads connections onto the back of the left hand cylinder head & a "contact dealer" message came up on the instrument.panel which usually means PCM failure.
On the left hand side of the car there's a positive power supply for the ignition coils integrated in with the air conditioning pressure switch wiring loom so that needed to be connected before the engine would even start as that wasn't connected either & the engine wouldn't start !
Yup. This was exactly my problem/solution... thanks for the video!
I am having the same issue. what is the blue wire going from your motor going over to your PCM on the driver side firewall?
Thanks for video, been working on 2004 silverado, no crank no start, dash lights staying, replaced ignition switch still nothing frickin going crazy trying to figure it out. Watched this went straight to wire it was just hanging like you said fixed ground problem started first try.
Mitch and Son in Law Will Drake. 2004 chevy 3500 dually.
Just replaced both knock sensors underneath the intake plenum. Had to remove the plenum and to do so we unhooked all 8 plugs to injectors and had to tie the harness on the passenger side up and back towards corner of firewall and fender. Made removing the plenum very easy. Got knock sensors changed and plenum back on. hooked up all injectors and other plugs etc. Got in and turned key on and all dash lights went crazy. Right away I new something wasn't right in Denmark. Turned key to start position and lights went out then back on and went all funky but no crank . Turned key off but all lights stayed on. removed key and different lights blinked on and off then stayed on with key out. Had to remove battery cable to shut dash down.. My son in law started googling and found your video. He checked and sure enough that wire was broke and hanging behind firewall. While pulling on harness and tying it back we had broke the wire where it was grounded to firewall. reconnected the wire to ground exactly where you did and the damned truck started on first crank. You are a God send and thank you so much. Hope your video helps many others also.
This video is a perfect example of why we, as diagnostic techs are in business. It has nothing to do with it being a Chevy. It has to do with competent diagnostic ability and knowing how to perform proper repairs. Good for you getting it running, but have a professional fix that ground the right way.
Thanks for your research ,really helped bro✌🇺🇸
dawg i love you rite now my brother. i spent all kinda money on this dam truck watched all kinda video. got up this am watched your video did what u did an i be dam. thank my brother
Benzarie Nelson glad I could help
also theres a ground strap under the truck that wreaks havoc as well
leading edge of drivers door follow it straight down under vehicle to frame of the vehicle its alongside your throttle cable remove ground clean all surfaces well (sandpaper ,scotchbrite or a good wire brush) replace ground to original position and your good , this ground can cause the reduced engine power fault
Very helpful! Thanks for the post!
Great info. Thanks for sharing!
I have a question did the rpm go up but wont shift or how did it dp it mine acts funy but wire was not that lose moved it a lil and broke off quick
Wow. Sorry for your $400+ of trouble, but thank you, brother, for sharing what you learned. It may save somebody else all that headache.
I own a 2007 Chevy truck thanks for your video.
This might be the video that finally help me out!!!
Any luck bro?
Awesome video. Thanks, Bro.
Now you need to put in better quality ground wires; understand that there are several on all vehicles. Make sure that the attach points of all the wires are clean and use dielectric grease on the connections. Good luck Sir!
The fuel pump cutting on when this happened? Im having the same problem but i jumped the starter and not getting spark and the fuel pump isnt turning on when i turn the key on
Thanks man helped out a bunch
Everything completely died on me when I was driving. I had power to nothing. The ground wire split in half. Luckily it was a cheap and easy fix.
Probably one of the scariest things that’s happen to me plus I had my daughter with me. Glad you enjoyed the video.
Tell me about it! Same thing happened to me. Except, I took it to Chevrolet. I have a 2003 GMC Yukon SLT 4WD. I told them I thought it was the ground wire. They said they would look at it. They said it was the ground wire, but that they had to take all these assorted parts off the vehicle to access it. Charged me $400 something. I personally think its a set up - scam by Chevrolet. It happens to a lot of vehicles. Should be classified as a defective part issue and there should be no charge for the fix.
Spent all that money for nothing,dam shame,bs mechanics,smh,hey fam glad you finally figured it out and thanks for the information....
The ground point back there is a major issue,, that ground has a few different wires on it. Within a year your truck is not going to start again but this time another wire is going to break free from that ground point. That ground is for the ECM and a easy fix is to take one screw out of the engine computer and put a wire on the screw and run it to battery ground. 👌
I would recommend using a thicker gauge ground wire when hooking up to your existing ground wire. Two ways you can connect it. You can use "Scotch Lock" connectors, these take the hassle out of soldering. Then use shrink tube followed by a plastic wire guard. Or you can just solder the existing wire with shrink tube. I preferre scotch locks.
Thank you so much for the share!
Thanks for the video tip!
Thanks bro, I'm about 500$ in the whole because of that stupid ass wire.
I have a 2002 Chevy 1500HD exactly the same thing happen to me thank you for the video
julio canahui me tooo I’m having the same problem
"And I was like..... Mothafucker!" Lmao, that's my go to word,every time I raise the hood....
yes.... YES, nods head vigerously
Thanks brother I just fix my truck cause of this video
Thanks, this was the problem on our 03 tahoe, I just posted a slideshow on it
Nice 👍 video I will save this in case this happens to my truck
Thank you so much!
If these parts changers were really mechanics, they would of done a voltage drop test and found it
I pulled wrenches for 15 years, ASE certificates in 7 of the 8 areas at the time. I got out due to the need to obtain training that employers either did not want to help with or you got their brainwashing blurb school. One thing I remember printed on the side of every Sun Oscilloscope was "Test not guess". I have lived by that since I saw it. I have been in Industrial Electrical Maintenance for over 30 years. Finding issues like this is an almost daily occurance in a variety of settings.
@@thegreenerthemeaner 2007 Tahoe headlights flickering. Any ideas?
@Peterbilt Pilot thanks buddy. I did a charging test on the alternator and it was charging low. New alternator fixed it.
Joey Sanchez check your light control module in dash common problem in these chevys
Same shit happened to me lol. I did find a video on CZcams though and found that exact issue before I started paying anyone. Thank god.
Lord have mercy. THANK YOU SIR !!!!!
WAS YOUR ABS LITE ON WHEN YOUR TRUCK CUT OFF????
There is 1 groud like that on each side of back of engine .sometimes it is still attach pull on it it will break easy , good luck !
Is there any video out there where is shows you how to do it.. having trouble even though it sounds easy
OK happened to my son making pickup at airport 2 hours away....Somehow got jump and got things going again....watched several videos (2004 Crew Cab Chevy 5.3) and pulled on the wire seemed tight....next morning transmission indicator leds were flashing, Jumped, and has run with all gages working again for several short trips around town...Perhaps just got enough corrosion lose to get it to ground again.....our wire was Black with white stripe.
Buddies dodge ram had a similar problem.
Dealer accused him of modifications (none). After 4 months of back/forth, they FLEW in their Master Tech,
Fixed after a hour. Samething i was taught.
Always check your grounds first.
thanks big guy, got it rev'd up
Mines have over fueling issues and i put a new fuel pump and filter in it and a MAF sensor and it still does it coule a bad ground cause the over fueling and the pcm to read running lean ?
I’m not to sure about that. The ground wire I had issues with completely shut the truck down.
i appreciate the vid!!!!! lucky for me however, I found that my "NEW" reman alternator was crap! sorry you had to lose so much feddy Bruh!!!!
Man thanks that's what happened to mine
Dammmn bro that sucks!!!! I’m having the same issue I will try this tomorrow!!! Thanks !
Why waste money throw in parts at it bro,go to a reputable shop,problems solve bro.Glad you got it figured out
I hate you spent all that money but you saved me a lot of money thanks
Seems like that geneeration, '99-'06, Chevy/GM's with those Vortec engines, have an issue with grounds failing. I recall some dude has great vids on that specific problem and how to remedy it. Big Three, etc., etc., etc., but more importantly, how to correct that lurking issue.
Background was meant to be on the block not the body if you want to relocate it fine but put it back on the block.
I have mine running to that same ground that goes to the hood also. The original spot had oil on it my cluster still isn’t working though. Hasn’t stalled on me yet 🤞 hope that doesn’t happen.
question i Have a 2000 chevy suburban 5.3 engine i been researching for the past few hours couldnt understand so is the two ground black wires with the white stripes hooked up to the back of engine block cut and then hooked up to one single wire ??? i would appretiate the response
i hope i made sense
I had two wires in that wire loom that was not connected what's the second wire for then
Same shit happened to me lol. Found video On CZcams though that helped out and was able to fix it before I started paying any body. Thank god
what kind of noise was making when you tried the key to star please i m trying to figure out i have similar problem meaby ....thank you
report7777 it May chatter n sound as if you have engine damage, sputter uphills, headlight may flicker, hitting large bump may change drivability temporarily.
good info, thanks
The grd wire looks like at #10 so a similar would be well devised. Better to over size then under. Depending on your area , any grds which I do/ redo I use Kopper Kote it lasts longer the the other has more oil to keep that area from rusting sooooner. Don't like doing jobs twice.
question. the problem i have is my tahoe wont crank or turn over. i tried everything i could think of and replaced alot of parts. could that ground wire in the video be my problem? i checked it out its not broken i tugged on it but should i try to cut it and re ground it?
It may not be broken but there may be a bad ground somewhere. I’m not a certified tech but I would recommend taking it to one.
Thank you sooo much bro !!!!!
Did they tow your truck on a flatbed truck? because rolling the trucks wheels, front or back, will burn up your 2nd or third gear depending on the average speed the tow truck.
Happened to me!
Man you might of just saved me from selling my truck, I thought I had a short in the column but mine is doing the same thing and I swap three trans out and now that I think of it I never hooked the ground back up I don't think.
Good information
Thanks
Thank you for the video God bless you my brother!!!
Mine is a lil uderpowered though new by about 45 CCA's . Sounding rough when it used to start . Just got it out of shop . I hope I didn't damage starter or anything else . 2016 Ford Focus SE 2.0L
just changed mine last week and it was the cause of my door locks acting crazy
Ground problems are common on chevy's
Haven't had one yet fail me every gm Chevy I had grounds are bad but everything else makes me keep buying them once you learn everything your unstoppable long live gm Chevy
My Tahoe caught a small fire last night from the cigarette lighter 🤦🏻♂️😂
@@carlosherrera8541 holy shit 😳
Check and clean all your grounds. Had the 4x service and it took cleaning two grounds for some odd reason. Look up ground loops for additional info.
have that issue on a 04 Avalanche...
The new ground wire needs to be heavy gauge. The same as the original.
Thank you! A rat ate the wire & I had no idea where to wire it up at.
my truck has a hesitation did your truck had a hesitation problem first before it started dying out on you like less power.
And this is why I'm fed up with being an adult, when crap like this happens....
