Dodge Dakota No Start, No Fuel Pressure Testing
Vložit
- čas přidán 22. 10. 2017
- In this video I will walk you though some basic spark and injector pulse testing before we find a no fuel pressure problem. Fuel pump power and ground testing will be shown as well as operation of the ASD and fuel pump relays. Trouble codes can be misleading. The cam sensor fault in memory had nothing to do with this no start condition.

Not only did you clarify how motors work, for me personally. You've also inadvertantly given me an excellent idea for the completion of my invention Paul THANK YOU SO MUCH BROTHER!!!
ScannerDanner:
You have just added one of the most important aspects of effective teaching/learning to your videos!
That is, a summary with diagrams.
Please continue to do this for all your future videos if possible.
The six steps to effective teaching/learning:
1. Tell ‘em what you are going to tell ‘em. (Overview)
2. Tell ‘em. Using diagrams and examples. (Content)
3. Tell ‘em what you just told ‘em. (Summary/review with diagrams.)
4. Answer any questions the students may have.(Clarification.)
5. Have the students do it. (Hands-on)
6. Test ‘em. (Evaluation of teaching/learning process.)
Lasting knowledge comes from:
Reading it.
Hearing it.
Writing it. (Note taking)
Seeing/smelling it.
Feeling it.
Understanding it.
Doing it.
Your method was excellent before....now, you are a true Master!
Thanks!
Thank you so much James! This is what I do on ScannerDanner Premium (sorry, shameless plug)
Indeed if we had all gotten that quality of instruction K-12 the world would be a different place.
Without a doubt the best teacher anyone will find,thanks again for sharing👍👍
Prime example why diagnostics and having foundational knowledge of cars electrical systems and schematics is just as key as removing and replacing parts. Much respect for these KT's your providing.
Had nearly the same problem in a 92 Dakota V8 checked all the way to the back. 100% sure its the pump, dropped tank, changed the pump, NOTTA... dropped the tank again suspect bad pump from part store. Decided to go a little further, turned out the wire to the terminal at the plug inside the rubber plug was broken. hard lesson learned, as the after market pump was $118.00, and was not as good as the original. FYI dble check at the plug terminal ends before buying the pump. Even probe the pump terminals once you drop the tank to prove it's bad. Love your videos..YOUR A COOL DUDE. Wish I had found your channel years ago. Keep up the great videos.
Happy to see you and your son together Paul!! Thanks for the great video, God bless.
Hi Paul your diagnosis using the test light to work out pcm control side ground either through ignition switch or scanner was brilliant. You are teaching all to be better Technicians. Great job from Uk
Thank you Paul
Absolutely right..Mr.Danner..The explanation on the diarmam is analyzing everything...Just perfect...Thank you so much..Greetings from Greece.
Caleb, nice camera work!! Paul, awesome thinking and explanation. I like your frame thought and reasoning. Love it! Kept me engaged during this video! Learned a ton of info! :)
You are brilliant paul whether you have or you didnt have the perfect tool you're able to fix the car, that's why i love your videos
I know this is a old video but as a 6 year ASE mechanic that fixes and flips cars, I always love watching these videos. They remind me of my beginner days when we had what I call the Ol' Original Gangster mechanic's that have 5 massive tool boxes filled with mostly custom made tools and they would always be in the back corner of the shop lol. when you dont know how to get to something or cant trace something down. They'd show you a thing or two and have it fixed in a fifth of the time it would take me but I'd learn old and new techniques which was priceless haha then I'd owe them a 30 pack of beer. Great video guys loved it.
Scanner Danner your the best teacher......I like you, you really explain everything and precisely.
Paul it's nice too see ur still uploading content to ur free channel.may u go from strength to strength!
Thanks bro
My pleasure Paul
Thanks to Mr. Danner i was able to diagnose and repair my car myself numerous of times since I started watching this channel back in 2012/13. I learned so much incredibly useful informations, I started to understand how my fuel injected car works, and eventually I saved lots of money on crappy mechanics, being able to fix my car myself. Thank you Scannerdanner!
Yeah man! That's what it's about. Now come join my premium channel to really get into this stuff and start charging other people for diagnostics like I do. $100 a call is what I am doing now.
www.scannerdanner.com/join-scannerdanner-premium.html
great job. I love the part of trying to figure out the fuse box arrangement. I have a 99 Dakota and just went thru the same thing today. I thought it was just me that couldn't figure out which was the real fuel pump relay. Thanks
If you teach at the college level, you are a professor. Always interesting. Thank you for sharing, professor.
Good call, checking spark at the plugs. Spark at the coil doesn't address a bad distribution issue.
That's why we love you, Paul!
Scanner Dan....I Truly appreciate your analytical thought process in trouble shooting and thoroughness in making these videos. I am a women trying to figure out why my 2005 Hyundai Elantra will not start. Replaced the fuel pump, now have a fuel filter in hand to replace next. Just spent over $1000 on mechanic for other issues, so trying the DIY road if I can stay out of mechanic shop for this issue. I have ordered various diagnostic tools, and studying your videos. You are the coolest guy, and have best channel out there in youtube arena for car issues.
Sweet! I will help however I can. Also join my forum on my website okay? IT is free and we offer great support for the DIYers out there.
www.scannerdanner.com/forum/post-your-repair-questions-here.html
Hope to see you there. If you end up posting something, let me know. You can reply here. I'll see it
@ScannerDanner i have to give you props for the way in which you take your time in explaining " the whys " of what your doing .... i have come across several Diagnostic videos,s on youtube an although some go through what their doing not many actually explain the " Whys " of why they are doing it this way or that way, or go into detail of what the part their working on actually does, which is what i really like about your Videos is you take the time to explain the " whys " of what your doing rather than just showing people what the problem is an how to fix it, keep up the good work Paul ...
Thank you so much Scott!
thank you for posting because with each video we gain more knowledge maybe this one i know it i could spray a starter fluid in the air filter but its not the right way i enjoyed watching the right way
Great vid Paul, Your teaching abilities excell
Kept sending them. U got it going on. Great stuff Thanks Paul
I took a month off from the online course after day and night study's with it and thank God because everything makes sense. Successful vacation. Back to the course. It's so intense that you need a break.
I love your no start videos so thorough. I could watch them all day as soon i can im subscribing to premium

These fricking fuse box covers...
Great team work guys.
case of a missing relay man ur the best keep up the good work am a huge fan sir
Awesome just pure real life senario awesomeness...this is real auto education at its best. Thanks for posting these videos
Exceptional video as always Paul, thank you!
yes sir all the extra info is greatly appreciated,ty;almost one year to the day;)
Thank you Paul. Keep up the good work. Bless You brother.
thanks for the vid. i like how you covered everything it could possibly be. alot of techs would fire a pump in it. and be correct. but at the end of the day being 100% shure before your fire the parts canon at it. is the best way to diag
Good video! A note on the Power Distribution box lid diagram to others working on a Dakota - the fuses and relays are in the positions shown, however, due to the shape of the box, the (A) bank is printed on the opposite side of the main bank (B) from where they are actually located. It's confusing, but if you look at each bank diagram as a separate entity it becomes clear.
I got a great laugh out of this vid, when ScannerDanner hit that same wall, WTF? what kind of engineer designed this fuse box.
im glad im not the only one!
Thank you for this video.I have the same truck with the same issue. I am going to start with the spark/ignition side first like you did since it's the easiest to check.I don't have access to a computer scan tool.
Paul, Another oustanding video and lesson. Thanks
Good job Paul! I was thinking about the slowly dropping voltage at the positive feed of the FP coil, when you took the jumper wire off and I belive that is another method that confirms what you said: that indeed the winding of the fuel pump is opened. The energy stored in the solenoid (by autoinduction) shoud dissipate faster with a low resistance grounded path through the coil (with a good pump). Of course, when the only path (through ground) available is your high resistance voltmeter, it takes longer.
Excellent as always Paul.Thanks.
You've got me into excellent habits, brother! I just repaired a short in one of those yellow dual rotating beacon light bars on a contractor's pickup truck - was thinking of everything I've learned from you along the way. Went down the wire, section by section, and eventually ran into a BUTCHER job on some wiring connectors, lol - turns out the owner's son hooked that light up for him. There were bare strands of copper hanging out of those cheap blue box-store connectors, and shorting directly into the cheap blue connector for the ground! Only mistake I made was doing an amp check with my meter - I briefly saw 29A before it nuked the fuse, LOL. It happens - 18 years with that meter, and I've nuked my share of fuses over the years. :D After I cut a couple feet of un-needed wire, bad connectors, and an un-needed switch, the lights drew 5.56A. Fixed! He took that off the excavation bill for my barn addition (where my new lift will soon reside!!). Every dollar helps. THANK YOU Paul!! :)
Awesome Smitty! Great to here you are applying this stuff and making some money doing so. Thanks so much for your continued support.
Awesome , this makes my day to have another Danner video . whooo Hoooo!!!
I think this channel is awesome you are a very gifted technician mechanic I think you should have your own TV show I watch your videos all the time and I learned a lot Ben Tankard with cars motorcycles lawn equipment in diagnosing is one of the hardest things thank you so much for putting these videos out I like to meet you one day and Shake Your Hand I go to Pennsylvania twice a week
Awesome explanations Paul. I learned a lot from this video. Thanks)
thank you for the tip about Lisle 20700 Coil-on Plug Spark Tester to test spark
Best video for Thanksgiving
Almost 100%! They only bit I would add is the multi plug on the fuel pump,sender unit? You probed the wires close to the plug but without actually undoing the plug and checking on the contacts then there is always scope for a problem here. I speak from experience, pushed back pin in a plastic molex multi plug that stopped a fuel pump from running! I was convinced after doing very much the same as you that it was the pump. Only when changing the pump did I find the pushed back contact.
Like you I carry a full load relay tester in my kit. I runs a cycle of ten operations and carries out a milivolt drop check on the contacts and gives a pass/fail status. I also have a relay break out box kit that comes in handy. Sandwiched in series with relay it gives readily available test points.
no argument here my friend, but for us, getting to that connector was not possible so the tank is coming down regardless and these would be standard tests when installing a new pump (if I'm dropping the tank, it's getting a pump)
thank you for the mini lesson, helped me understand better.
Excellent description
great video Paul. very educational and entertaining.
Man has patience I would have been smoking and I don't smoke. Very good stuff. I got that!
Another great video
Thanks.
Cardboard education. Love It! Well done.
Great work and a great lesson, Thanks for sharing
This video couldn't demonstrate a more practical example of a faulty fuel pump than this! Real life.
Thanks Ozz!
great lesson, best teacher!
nice one. good systematic approach.
excellent video SD
At First, I thought is going to be an easy one but wasn't another very nice video training class thank you, Paul, also thanks to the cameraman and to Pete Latoure Perfect! I like the rain but I don't like cold I don't like snow thanks
My 02 Dakota has the exact same issue .with the fuse box and legend. Your relays are correct in their positions .I know because I was driving and then when I went to leave work the truck wouldn't start and I work by myself. No others messed with the truck. Dodge goofed up on the legend printing. My relays are in exactly the same positions as the truck in this video. I think it the fuel pump as well
Another perfect ending explanation that make sense
Thought that you learned a lesson in your driveway ----- Never - NEVer-- NEVEr -- NEVER!!!!! put your scanner on the windshield!! lest the wiper throws it to the ground and scratches up the screen!!!!!!! Chuckle Chuckle See, us old duffers remember what we learned in your videos. Keep up the good work and keep your scanner safe Bob L
Great video Danner. I can do all these test with simple tools............thanks a bunch...... skills that makes me wiser.
yes you can!
Great lessons here. Nice work guys. Thanks!
Thanks bro
Very good dimo Stration
Good video Paul. The fact is not need to check the ground is cuz 0v tells me is good and the pump brushes are not making contact. If the ground has the chance to be open somewhere after go thru the pump u will see most likely 12v or close to batt voltage and is not the case here. I left the video at 45 min
excellent video God bless you sir, you clarified a great doubt,,😎
Very cool, props to Camera Man Caleb! Big fan of the junkyard style cardboard digram too ;)
Thanks Noah!
Im word less, impressed and full of gratitud to you., god bless uo
Great video
Great Video!
good stuff Danner, thanks.... But may I suggest a fender cover
Great video Paul. Doing chapter two of your book right now. Great book glad I purchased it and signed up on premium also thanks artie
Thanks so much Artie!
@@ScannerDanner HOLA DONDE CONSIGO EL LIBRO BOOK KE PRECIO TIENE PRICE DONDE LO VENDEN GRACIAS POR INFORMACION
@@reynoldfloresluna8896 My book is available at www.scannerdanner.com and I have a Spanish version of my eBook coming out soon. Thank you!
Now that's what I call learning something
the discussion at the beginning of the vid about california emissions was important. sometimes that issue is confusing. the sticker sometimes is not comprehensive.
your son does a good job.
I have that exact spark tester...I think it was made by Performance tools.I have way too many spark testers and fuel pressure gauges, LOLAs always, outstanding video Paul
Excellent... well done...
You make me miss my daddy :)... He was an awesome person to diagnose my problems.. Even though I listened & helped him with fixing things, I am still no where understanding the circuits lol... I have a 2000 dodge dakota no crank for try then a crank on the second try.. Guess I will check fuel pressure! Thank you & your son for the video sweetie...
Katrina Georgia Girl no crank on the first try? Or cranks but does not start?
I'm sorry for your loss Katrina. A no crank issue is related to the starting system. Do you mean a crank, no start? Then on the second crank is does start? Or are you saying it doesn't crank over at all. Meaning no starter sound
ScannerDanner : Yes your correct, I meant it does not start on the first try, but eventually does on the second try after a long crank.
Keith DeFazio : does not start on first try, but eventually does after a long crank on the second try!
so I would describe that as a "long crank time" problem. Definitely get a fuel pressure gauge connected BEFORE you even turn the key on for the first time of the day. Check your pressures during the no start condition.
Thanks Paul and Caleb =)
Thank you Pablo
the adventures of mr danner!
this guy is great mec
The best way to understand that fuse box lid is to think to yourself that the lid itself is a stamp , like you would use on an envelope. If you imagine pressing it down and getting an imprint and looking at the underside of the lid it will all fall into place. Diagnosis begins at 28:40 😁. Great video and great way to show why we don't fix codes , we fix cars .
I looked it up and the decal is definitively wrong...that'll get you chasing a rabbit down the wrong hole.
Not true, the first 15 minute were good too (spark and injection pulse testing etc), so only 15 minutes of me chasing a fog light relay , not 30 as you're suggesting
It absolutely wasn't just a mirror image was it? Part of it was and that was the issue, only part of it.
ScannerDanner Yes the lid was wrong.
That is great Troubleshooting!!!!
thanks for what you do
thanks for watching buzz
Just ordered your book. Can't wait 👍
Thank you so much! Be sure to check out ScannerDanner Premium here www.scannerdanner.com/join-scannerdanner-premium.html I will take you page for page through my book as well as provide you with hundreds of exclusive case studies.

yea if you are real smart learn every thing in 2 weeks and will not cost anything i am joking there is a lot to learn
SKO NYC you will never regret ! The best tool you can have in your tool box !!
I bought Paul's book and secretly thought I'd watch all the premium videos and unsubscribe before the end of the free trial. I did watch them all before it expired, due to a couple of weeks off work and my wife and family gone at the same time, but I was so blown away by how good it was that I'm still a premium member today! You will not be disappointed! Subscribe!
That's awesome johnaclark1! Thank you for your honesty. I do have a lot of turn over with the 14 day free trial and that's to be expected, but even with me paying for bandwidth now, it is still worth it. I need people to see what is there. I'm convinced that most stay when they see what's really there. Your comment cements this thought process for me. Thank you so much again.
Excellent process. Even the misdirection was a good learning tool. We can't always trust stickers. :)
Gracias por compartir tus conocimientos
Gracias por ver a mi amigo
Its so good to see videos like this to refresh our memories and learn few others things and to see how other techs deal with problems like this. Thanks for the great video lecture. After years of watching your vids its so great to see how passionate you are on what you do it gives me motivation to learn more as I progress and makes me more efficient as a tech. Anyone reading this I recommend purchasing SCANNERDANNER BOOK it comes really handy and great over all book.
I've worked on a vehicle (mazda) with a bad fuel pump. Checked power 12v and ground to be good by back proving connector from pump. As I removed fuel pump connector I also found connector pin burnt out and harness needed to be replace. I then rechecked fuel pump and both needed to be replace.
Thanks so much!
Good diagnostic. Tech. Salude noel. Matute
Nice video.
Thanks for great lesson
thanks for watching!
For me Mr.danner has been my teacher since I knew his channel and being in the premium too and I've learned a lot. Thanks to him thanks Mr danner. Hopefully one day see u in person. Thank u I recommend SCANNER DANNER !! 💯%
you are the man dan
Thank you, but my name is Paul :-)
It's okay though, I get "Dan" a lot from my last name Danner
ScannerDanner Don't be bashful Dan😁
middle finger emoji to Keith DeFazio
ScannerDanner 😜
Nice vid. It looks like the legend on the inside of the fuse box lid is depicted as a mirror image. No idea why they'd do that, but I've heard that Ford do the same thing these days. Sometimes, you just have to look at the physical layout to work out how to decode it all. :-P
Great video....I have a dodge Dakota (been sitting for about 4 years) now wont start... it tries to crank just like this one in the video... sadly I cant do the work myself, but I'm now knowledgable so I wont get ripped off by a repair shop.
Step one. You will need to drop the fuel tank and get rid of all the gas and change the fuel pump and sock strainer and in-line fuel filter. It is possible the pump is still good. So a psi check would be first. But I wouldn't drop the tank without also replacing the pump.
Step two, Your injectors are most likely stuck shut from the varnish build up, you may need to replace those too. If you are lucky you may be able to get them to start firing again my tapping gently on them BUT you HAVE to get rid of that old fuel!!!!!!
@@ScannerDanner thanks for the reply!!! I'll let you know what I find out .. hopefully it wont be too expensive to fix...
Awesome. Now I know how to check my 91 when it has its intermittent no start. Odd last time it died on me I banged tank, swapped relays. Nothing. Ended up having a gal of gas in back, kept feeding throttle body with a squirt to get it running. After 5th or 6th time it stayed running. Thinking fuel pump in my mind. Only does this when it's hot out and just under 1/2 tank of gas
Mr scanner I love your videos.it does help me alot when I can understand it..how can I get your book
Spray first, check pwr to pump, pull tank if good pwr. If no pwr, dance with relay operations....
I see some Chrysler use mirror image on PDC lid and others are as they are. To make us good and nuts! I'm 62 and been driven nuts from these. CK the pwr to pump first, then if you want to know what relay controls it "pull relay's". I find a power probe will knock out these uncertainties in seconds,, not even minutes. It's a good little friend for measuring voltage numbers as well....
THX..
Once did a FP on a 90 Chevy pu w/454 tbi. I put a fuel line adapter in place, and proved to the owner that it was indeed a FP issue!! It was hot as blue blazes! There were multiple wasp nests! I ended being chased out twice by brown recluse spiders, one was right where I had been touching in the darkness, the other crawling on my overalls as I took a leak!! Was a hard job, took a long time, got the new pump in, and he wanted to see fuel pressure!! WHAT?? NO FUEL PRESSURE?? REALLY?? I crawled underneath, and disconnected the line at the filter, and SPLOOSH!! I got hit in the face with pressurized fuel!! In my eyes, in my ears, I was almost taken to the hospital because it was so bad!! Took me two hours to get back to it!
I had lost the little nipple inside my fuel pressure tester, the one that depressed the valve!! Oh, the fuel pump was bad, and I replaced it. After the fix, it started and ran, but before I started it, I showed him the NO PRESSURE, and took that as truth!! GOT LUCKY???? Not a chance!! Wasps, spiders (I am deathly afraid of spiders), fuel in my eyes, ears, nose and mouth, worked for hours in the heat and sun! I got stupid, not lucky!! But the parts cannon worked this time, just for the wrong reasons!!
crazy stuff man, thanks for sharing
ScannerDanner you're welcome, Sir! And thank you for what you do!! I have learned a lot from these videos, even tho I'm not much able to work on cars anymore!!
Great video Paul Ford fuse boxes are worse than Dodge
Great video! I see you upgraded to the verus edge btw lol
Hi Paul, I like this video, very thoroughly helps me understand more keep making this interesting no star videos, by the way, what was the year make and model of this vehicle so I can study the wiring diagram? I’m trying to learn everything I can from you.
Also, is your online class ready now and how to sign up?
Fun video to watch.
Thanks Richard.
This being a California vehicle, they ran a separate relay for the O2 sensor heaters. On the older systems, they did not, the ASD or the Fuel System relay did. Also if my memory is correct, the Alternator field power wire feed was shared with the LDP.
Thanks jarin!
thanks for the video. I literally walked outside and hit my gas tank with a mallet a few times and truck started right up lol
Awesome!
