TOYOTA TUNDRA DIES STALLS WHILE DRIVING DIAGNOSIS

[@jimm2442]

I am a retired mechanic with 35 years of on the job experience. This man is good at his job! Clearly he takes a step by step logical approach in diagnosing a problem. He understands how the systems work and that is the key in diagnosing and repairing a problem. If I had to pay for vehicle repairs I would want this man working on my vehicle.

Hi boss my name is jameel Ahmed I am auto AC technician job

[@viplegaleducation1292]

Agreed, sad part i see as a consumer is that you have to know how to find the good techs. Alot of par or sub par techs running shops.

[@WoodLox]

Exactly so. As a mechanic for over 15 years I became a technician when I noticed most shops either didn’t know how to diagnose or misdiagnosed. It’s cheaper to find you someone that can pinpoint issues with accuracy instead of paying parts changers. I’ve seen trucks immobilized they change the ignition fuel pumps and run wires that burn up fuse panels and ecm/pcm’s. Once I notice these hacks I refuse service. It’s best to take it to the dealership than trying to save a buck which basically totals out the vehicle.

The real problem is finding someone who is WILLING to do this type of troubleshooting, to say nothing of finding someone who knows what they're doing. Great example of specialization and trade, here we have a guy who's smart and skilled in this particular area of automotive repair. Thanks for the very interesting video.

[@westfield90]

Excellent. I don’t think 90% of mechanics would have picked this up.

[@annbotnick8247]

Well done! I’ve watched two of your videos and I haven’t been this enthused in my 65 years of being a mechanic. I’ve always considered myself an automotive electrical specialist. You’ve brought us old world mechanics into the mysteries of electronics with the way you explain & demonstrate. Your thought processes of elimination are eye opening especially for us mechanics that are not part changers. Thanks again for your efforts to educate us! Good job.

[@andrameda1]

Dear advance level tech Mr. Eric, Your skills are impeccable as a diagnostic tech; Your understanding of integrative circuitry is awesome; Your observations are astute leading your mind to discovery unveiling the mystery of low and high electrical currents and shorts; opens; damaged wires; and really resolving the car's pain and suffering. The machine does not feel pain because it is inert however the owners feel pain and suffer over their metallic horse, it becomes a threat to the quality of life when it fails to run. Your ability to teach is receptive and exceptional because I am able to learn from you, perhaps because I feel more relaxed and at ease, when you teach. Perhaps you have a rare quality in your spirit and a genuine caring, that allows many to open up their minds to you, its a wonderful mystery, I do not understand. I was a student of automotive repairs in the 70's when it was easier to fix a car then, now I am a retired old man learning about integrative circuits, baffled and further confused because for the last year I have not been able to fix my corolla 2000, a cranking no starter, with a stuck shifter in park, brake switch and pedal with no resistance to floor; and a fuel pump that does not prime. The ignition fuse 7.5a intermittently blows; and 2 wire, 5 v ref, pull down system; cam and crank sensors in question. I am reading text books and watching many videos and I cannot seem to grasp the behaviors of electrons, that is why I want to praise your work and experience. Thank you for serving others and empowering me. Peace and serenity to a good fellow, Mr. Eric, Bob Bishop.

Wow, what a great diagnosis! I'm not even a mechanic, and I couldn't stop watching!!

[@cs_yt]

My day job is also problem solving, but of a different kind. The approach you had on this one is right on. I hope your clients appreciate it. I could see shops replacing the pump, the pump control module and the relays before getting to the connector pin. I bet the problem came from replacing the tank, and the tank dropped while plugged putting a strain on the female pin. Great job!

[@dporrasxtremeLS3]

OUCH! Right on the Tenders!

[@spelunkerd]

What a brilliant case study. I am amazed at how bright a general mechanic needs to be to do this work properly. Even the fact that your customer came through KZbin is telling. That said, I would hesitate to publish your name or phone number here. Eric O has had all kinds of problems from people calling his office for free advice, it became a real problem. Strangely, celebrity can come with all kinds of complications that can cause a drift in channel character and unexpected problems.

[@jamesrudolph9054]

Nicely done , now people can understand why fault finding is so time consuming and if not done correctly cost can escalate and no real fix is achieved. Customer made the right choice to bring the truck to you .

[@ADVANCEDLEVELAUTO]

Thank you

[@faustogonzalez8397]

Awesome video, the difference in voltage between the two monitored points is what creates current flow and therefore fuel pump rotation. The Pump ECU generates a floating ground to control current flow thru Pump and therefore controls fuel pressure. The ultimate difference in voltage is determined by the ECM to control ultimately the fuel pressure/speed. Great video, thanks again.

That's called a wiggle test! 😊 retired 44yrs flat rate technician at dodge dealer's, would have enjoyed working with you, your diagnostic skills are top notch!

I have same problem last winter I do not do nothing everything works fine after 2 weeks and now I have sam a problem almost two weeks I asked the dealership about they told me probably I have a bad fuel pump but when I watch this video it gives me a lot Experian I'm going to look at it tomorrow I'll let you know what I come up with thank you so much great job

[@kassimyahia]

Finally I found the problem wiring bad

[@captinbeyond]

Impressed like the other commenters with your diagnostic skills and trouble shooting. Looking at the wiring schematic and seeing all the things that could go wrong , it seems overly complicated for just getting the gas pump to run.

[@gregs.4275]

Good job troubleshooting this problem . Intermittent failures are one of the hardest to find. I have a 2011 Tundra which is doing the same thing so that is why I am here. I don't think there is anyone in my area who can trouble shoot like this. I am leery to go to the dealer because all they will do is keep replacing parts. I am a 35 year electronic tech and I was leaning towards the ECU which was soaked with brake fluid but now I will have to dig deeper. Thanks for the video.

[@codywichman213]

great diag, now we can see that the 1.42 v was the bias on the ground side of the pump. shows that we have an open from the pump back to the module. it all makes sense in the end.

Bro they found you because you are bad ass at your job as a tech and owner of a auto electric shop, I have to say thank you for doing these vids for you can trouble shoot these vehicles faster than any tech i have seen, and you share your knowledge most techs keep to themselves, I actually do troubleshooting for customers over the phone as a courtesy to guide them if they want to spend money on a shop or do it themselves and so far all I have got from these customers is a big Thank you, that is good enough for me.

[@MassExMan56]

I absolutely like the content you’ve created that I’ve seen thus far! In the video clip that you took of the second diagnosing drive, I heard what sounded like the truck “bump” while moving like you’d driven over a change in grade or into a pot-hole. If that actually happened, then that’s when the scope picked-up on the change due to the “bump” moving the harness connecter as the two events coincide on camera. The scope is an awesome tool to have; a talented and dedicated technician is even better! Excellent job brother!

[@dbz5808]

I thought "loose connection" when during the test drive, going over the speed bump made it drop out. Great video, thanks for sharing.

[@mikechiodetti4482]

I've seen that happen many times. The ones I saw were on the power and control sides like you had, except mine got hot enough to make the terminal turn color and lose it's spring tension. Replacement of the connector assembly solved the problem. Not to be a put down to you, cause that terminal still had the "shiny look" to it and held it's spring tension, meaning you did right. Good Fix!

[@billrimmer5596]

Wow. That was a good one! I thought for sure u would have lift up that bed and change the fuel pump. I’m thinking there was a time when some dirt or corrosion caused a little bit of high resistance on that terminal and warmed it enough for it to lose tension. U restored the tension and cleared the terminal. Great use of the lab scope. Probably a pwm ground. Super Dooper Vid!!!

This is too funny KZbin told me to watch this video today I had just completed almost the exact same diagnosis I had a 2010 tundra that occasionally with stall sometimes not start. It had received two fuel pumps a fuel pump ECU and a fuel pump relay before it came to me. When I back probed the fuel pump power and ground wires I had that 1.44 ,1.45 bias voltage the entire Time it wouldn’t start. It ended up being the ground wire the terminal had come loose and had melted the fuel pump connector what I believe happened was the mail pin of the fuel pump assembly was riding on the outside of the female pin. Overtime the excessive resistance caused the connector to melt and just create more and more of a gap. Love the video keep up the good work
