Dear Oz Mechanics,
I wanted to thank you for your incredibly helpful video on fixing the no crank, no start issue with a Chevrolet Silverado. Your detailed guidance allowed me to successfully troubleshoot and repair my truck. I truly appreciate the effort you put into making such informative content. Keep up the great work!
Best regards,
Sergio Contreras
Thank you for this video. I was mis-diagnosing mine till I saw this video. This video saved me a lot of time and money. I thought it was my BCM and would have to be taken to a mechanic. Then I ran across your video and I went to work immediately on my truck. I found it was on the negative side that I was losing power. Thank you my truck is fixed..
I've had my truck, 2017 GMC Sierra in and out of the "CERTIFIED" Service department three times and they said they couldn't duplicate this issue. I SAY BULLSHIT. I find it very hard to believe that a whole warehouse full of techs. doesn't know anything about this issue with the battery cables.
Thanks for sharing your video it has saved me not only money but loss of income being self employed and has overall taken away the fear and weight off my shoulders of not being able service my customers at peak season!

I saw a post on Strong Towns about the lawsuit regarding parking. I work as a public planner in another state and I see the same issues here, though not to the same extent. The result is that the only people who can afford to develop are the big guys with deep pockets while the little guys are always priced out. I wish you the best of luck, I'm rooting for you and I'll be following closely!
excellent video...I applaud you for your presentation and knowledge...God bless
Prettiest sure it’s what I’m experiencing on my 14 Silverado, Oz.
Noticed the the only discolored connection on my 12V+ bus plate is at the load end of that little cable. GRACIAS, Amigo!
I just had this problem and my fix will be buying cut to length welding cable and lugs at my local welding supply. It's tough, heat resistant and high ampacity. I've done many cables that way for decades. Dielectric grease inside the lug before crimping excludes moisture.
Another part to look at closly is that 150 amp main fuse. Check it for corrosion an replace it if you see copper dust inside the holder. Some of the symptoms are door locks going up and down on their own an stalling. A feww bucks and my truck ran like new. the ends were rusted off of the fuse.

Best video ever thanks for the fix
THANKS FOR A SIMPLIFIED ACCURATE THOUGHTFUL DIAGNOSTIC. POWER TO YOU. THANKS
A failing connection where the cables are crimped to the positive clamp causes high resistance. Any resistance will result in voltage drop, and in this high-current cable will cause it to heat up and reduce the power throughput. It looks like the cable clamp is making good contact with the positive battery post, but not with the red cables.
It would have been better to bridge the bad connection with something passive, like a jumper cable, but the "booster" test is better than nothing.
awesome find
Thanks 👍
Take care and have a great day 👍

High resistance ( corrosion ) on the positive side , causing the heat in the cable and connection . The key was on during the test . ANY exposed copper will corrode and disintegrate over time . Great use of the thermal camera .
Would have to be some serious corrosion to disintegrate a battery cable.😆😅🤣
@@deependz3231 How about a ground cable with exposed copper on the chassis ? It gets a continuous salt bath !
@@billsmith2212 The silverish look on your braided ground strap is from tin, which is resistant to many common corrosive materials, and is plated on the strands to resist corrosion. So you see, there is no exposed copper, unless you freak out and dip the cable in some kind of acid bath to remove the green, which is harmless, and forms after many years of exposure to the elements, ex. road salt.
Have a 04 Buick Rainer with 5.3 getting cooling fan ground code, cleaning all grounds and electrical connections. Who could you recommend in the Houston area to diagnose my vehicle.
Hey! Quick question. What multimeter do you use? TIA!!
This Worked on my 1997 c1500 5.7v8
Thank you so much
I got a 2007 2500hd Z71 6L for 2200$ and it had the dash lights come on but no start. I purchased the truck anyways and towed it to my house. The guy who had it had it stored all winter then when it didn't start he replaced the battery but still nothing, no dome lights, head lights or cranking. I noticed it had no indicator line under what gear it was in. I ran a wire to the starter and positive fuse and it was cranking but no start. Then I thought about that onstar system that was in it. I Pulled fuse 47 or 48.. (I forget) and put it back in and just like that it started.
Hi Oz Mechanics, I hope you are well. Can you confirm if the instrument panel was lighting up with the key in the "crank" position? I'm having a similar problem with my dad's 08 V6. When I turn the key to the "on" position, all gauges/ gauge lights in the instrument cluster activate. When I turn the key all the way forward to the "start" position, all gauge/ gauge lights in the instrument cluster go blank. That includes the "anti theft/security" light. At that point the starter/solenoid does nothing and I get no power to the solenoid. Please let me know if this sounds the same as truck in your video? Thanks.
Nice example of thermal voltage drop!
A+++ instructions man you should be a teacher
Oz@Mechanics my truck is an 07 1500 and it has the Same problem but my wire is good I went to start it and nothing what else could be wrong
So I have a 02 Chevy Silverado 5.3 4wd i can drive it it’s just that the security mode is on it will cut off while I’m driving it just trying to what’s the best way to fix it
Thanks for another great episode. I hope everything is going well with the lawsuit.
@@OzMechanics I wish you all the best. I hate it when governments make arbitrary laws that where made probably to protect the big players.
Oz, hope all is well and good videos, I have seen you work with another awesome guy Eric on Advanced Level Auto and stuff. Your videos are pretty good and practically right to the point. I was curious if you also ever came across MY's 2013 to 2015 Chevrolet Malibu with the auto start/stop that has an intermittent stall out on auto start up. Thanks to Eric from Advanced Level showing a video a while back helped tremendously about the P305F. His 2 part videos on that helped me alot getting my 2014 Chevrolet Malibu back up and going. But I was just curious if you have ever come across anyone with that Malibu having intermittent stall out on autostart. Again, awesome videos and thanks for being part of a great group of other CZcams diag techs whether professionally and/or DIY. You all are a great inspiration and help.
It’s funny that you brought this up. A customer passed by yesterday, having this exact same issue. I set up an appointment with him to come early this week, let’s see what we find
@@OzMechanics hopefully you can be able to do a video on it as well, thanks man.
Just a question my friend .I have a 2009 Chevy Silverado and I was driving one day and turned on the blinker and all my gauges were fluctuating and the truck was losing power and lights were coming on and off .Drove it for another 10 miles and turned on blinker again and it ran normal .My mechanic looked at all the ground connections and said they were in good shape but one was extremely dirty and dusty.The truck sometimes before this incident would act the same way as the one that you were working on .Could this be the issue? Just wondering. Love the vid just subscribed!🙂
Never seen cable terminal ends like that ever.... good job... PS by the way what kind of camera was that to detect the heat coming from batt. cable??
2012 suburban same issue...I solved wit replace fuse box junction.
What part of Houston you in
My 08 avalanche is having a issue we're I can turn it on but at the moment I turn it off and try turning it on again it won't start battery if fully loaded and new
My 03 duramax is having the same issue replaced the battery and starter. Tried to jump it. Still won’t start battery completely dies when I disconnect the jumper cables.
Hey brother, did you ever get the bogus problem with the city resolved; them trying to make you have more parking spaces in order to operate your business?
@@OzMechanics may our Lord be with you and give you the victory against the ungodly tyrants
I put a motor in my 2006 and it won’t crank I can short the starter and make it crank but not with the switch , Chevy Silverado, if I try with the switch the dash lights and headlights come on ???
I have power but it’s just completely dead no sound at all when I try to start it.
Any idea what it would be?
It would be a cold day in hell if I would replace a battery cable because of some minor corrosion. 😆😅🤣
👍🏼👍🏼👍🏼👍🏼👍🏼
2009 Silverado just dies on me do you know what the problem is like I can go down the freeway and it just stops i have to let cool down
I am having the same problem with my 2008 chevy silverado i tried to start and nothing except my negative terminal is really hot
My 2017 Chevy Silverado turns off after 30-40 minutes of driving n it doesn’t turn on till the next day I’ve changed my crankshaft,camshaft n nun of my fuses are missing idk what to do
I have a 2003 silverado 5.3. I have a similar issue but mine does the same every other time.. I turn the key and it wont turn, click or anything, the cluster lights and needles kind of move a little bit but thats it. I just keep trying to turn the key a few times and it varies, but it will turn on normally after a few tries. After that the truck runs and drives great, it will just do this at least once or thwice a week. its weird and I cant find a fix. I`ve changed the ignition switch and key present sensor because i thought it was something there but still cant find the problem. Like I said, after a turn the key a few times (like 10 or 20 times) it starts normally. Any ideas?
You figure this out, man? My Tahoe is doing this. Won't crank sometimes until I turn the key several times but then starts and runs fine until the next time it decides not to. I also put in a new ignition switch but still the same.
@@klong2023 yes I followed the start signal all the way to the starter. At first I thought it was a bad starter but when I went to check the connection at the starter it had acumulation of dirt and grime. I just inscrewed the wire on the starter, cleaned them off both and tightened them back up and it worked, This issue went away completely and I didnt have to buy a new starter.
I have a non-start issue myself. All the engine does is spin over and never fires up. Just throws a crank sensor code p0035. Replaced cam and crank sensors and new battery NOTHING
❤👍🏻👍🏻👍🏻👍🏻
my issue was a bad ground... but my key doesnt start the car only the remote start
My 2016 silverado having issues. I put the key in and all the lights on the dash come on like normal but soon as I turn the key all the dash lights turn off, no sound, no starting, nothing. Any suggestions ????
@@josecool4880 check your cable from the battery. One + cable will go to the mega-fuse. Check the voltage on the out feed tabs of that fuse. If that’s bad, you’re gonna read a good reading on one and a bad on the other. ( a slight voltage drop) Shake all 3 of those + cables, it will probably have a strange reading again but on the other cable. I couldn’t wait for the actual OEM part. So get to harbor freight and buy 2’ of cable with the ring connectors. Tape off the old cable really good till you can get OEM. Also check your main relays, flip them around.
Did you change the starter ?
I have the same problem hot wire no crank changed the starter problem went away next day again but no hot wire now antitheft lock now and no start 🤦 try again today I guess any tips
Mine just stopped turning on after I got gas. Literally it's like a dead start it does nothing at all. I get lights and everything.
Mine still not starting man u know anywhere else i could look
It would get warm if there is corrosion causing a high resistance at the connection.
Hey there my 2012 Chevy Silverado will not start I put a brand new battery in it just now still will not start it will not crank over it doesn't make any noise nothing except the headlights turn on nice and bright and it's weird though because the mileage turns on even without the key in it I tried what you showed I have lights on the dashboard but the starter and engine still will not kick over or make any kind of noise
@@mtsanchez27 its still in the shop and they still don't know whats wrong. they are changing the body control module but they are not sure if that is the problem
@@nucknuck123 thanks for the input brother. Please let me know as soon as you know the good news 🗞️ please!
@@mtsanchez27 yeah u bet ! The mechanics say they are pulling there hair out over it its been there over 3 weeks
Hahahaaaa There ya go
Tpms module not going to sleep
With all those tools it took u that much to figure it out?
Got to do proper testing to verify the problem. Sure you would want your problem fixed right the first time
another stereo install gone bad ?
Bad connection!
