- In today's case study we have a 2015 Toyota Tundra pick up truck with a 5.7l V8 engine. The customer complaint is that the engine intermittently stalls or dies while they are driving. Using a scan tool we found trouble codes related to the fuel pump. Including DTC P0230 fuel pump primary circuit. Follow along as I explain system design and take you step by step through my troubleshooting process. If you enjoy these case studies, please make sure to check out my channel for my other case studies. You will find more useful information there.

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
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.
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.

I second that..Eric is the go to man and I 👍💯😎
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.
Excellent. I don’t think 90% of mechanics would have picked this up.
Well done young man. To track the problem all the way to a lose connector, bravo, bravo
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.
Hey i have a 2010 tundra it turns on but the idle is so poor it stays at 500 or less do have an idea what could it be
"Like tossing a hotdog down a hallway " has got to be the phrase that pays today. Awesome! Your analytic skills are truly something to admire.
Haha! Thanks for watching!
That’s usually a woman term lol or tic tac or like a light switch 😂

That terminal was looser than my ex-wife's morals.
All I can say is that you’re an honest mechanic which make people gain more trust in your automobile repair skills...amazing!
Unfortunately this man brings trust on other dishonest mechanics, and the chain goes on.
Lol "like tossing a hotdog down a hallway" great analogy, love the video keep those case study videos coming.
I don't know why that was all I could think of at the moment lol! Thanks for watching!
Wonder how many people would had put a new pump on the vehicle and still have the same problem, great video.
Agreed...that's what my dumbass would've done 😱
To be fair, you might had accidentally fixed it while charging the pump. “Let me just bend these terminals just to make sure”
@@StarrTile That's what my dumbass did. I've got some wiring to check. I've NEVER had a connector issue in 47 years of maintaining/repairing my own vehicles. It could very well be the first time.
I've seen numerous terminal fitment problems. This tech is a good one.
SAVED MY 🐴 Dude. Thank you so much! Couldn't figure out mine. Watched this and followed the fuses that lead me to bare wires grounding off my O2 sensor. Golden info Sir!
Awesome! I’m glad I could help!
Thank u for being an honest mechanic and not like others that ripp off customers
You mean like the stealerships???
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.
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 CZcams 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.
That’s the reason my shop name is different than my CZcams name. Thank you for watching!
This tool he is using is superb but if you don’t have the knowledge like he does it means nothing. 👌🏼
Great job. I'm impressed by your diagnostic skills.
Thank you!
@@ADVANCEDLEVELAUTO If you go back and look at the video. When you hit a bump the truck died. I instantly thought bad connection. Great job on finding so quick.
Outstanding job. Looking for a problem instead of replacing everything. Keep up the great work.
If you go back and watch the footage when you were test driving and filming just before the vehicle stalled, you said we are coming up on a bump just after you said that it stalled. At that point I was screaming check your circuit to that aftermarket tank something is loose. But you were methodical beautiful diag. Thanks bro. Good job!
You are an example of what an automotive technician should be. Honest and great at trouble shooting. Keep up the great work!
Love this guy. The antithesis of your “professional parts changer”.
Knowledge and patience pays off.
Wow very impressed on your diagnostic skills.
Great job for being an honest mechanic..well done
Not only impressed with the trouble shooting skill, but fixing it in place without taking things off the truck is equally impressive.
I admire the step by step logical approach in diagnosing the problem. This video is 42 minutes long and I didn't want to skip through because I knew I would miss something in the diagnosis. This was an excellent instructional video and I learned a lot about the fueling system on my truck. Thanks for the video.
This was like watching one of my favorite gun slinger suspense shows. Very intense! to the End! Thanks.
Great mechanic not just a parts changer. You have fantastic problem-solving skills these are hard to come by nowadays. Thank you for these videos you are showing people how to do it the right way.
I have never seen such sophisticated teaching on car troubleshooting. Thanks for you dedication
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.
awesome work! people don't realize anyone can turn a wrench but finding a real diagnostic tech is the hardest. Great work!
Variable Fuel Pumps can be troublesome to diagnose along with the fact the vehicle has a dedicated Fuel Pump Module which communicates with the ECU. Intermittent stalling can be a hard case to solve unless you can get the vehicle to act up with your scan tool connected and/or throw you a trouble code. Thank you for a great diagnostic video.
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.
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 .
Thank you
You don't know how the customer found you? You should be glad he or she did find you. It should be good for some word of mouth business. If it were my vehicle you would definately get lots of word of mouth business. Great job man!!!!!
Maybe they Googled the name?
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
Finally I found the problem wiring bad
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!
OUCH! Right on the Tenders!
He's still learning and with 45 years experience hands on, il tell you that everyone is never done learning on the vehicles and other junk that humans create.
Be happy this customer found you! A good honest mechanic is hard to find. Most would have slapped a new fuel pump, charged up the rear for labor and the truck would have been right back after hitting a good bump.
Another great video! Had to be to keep me watching the full minute by minute step by step approach. (My attention span can be limited) The connector, I didn't see that coming. Great diagnosis Eric! Keep up the great work.
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.
Wow, what a great diagnosis! I'm not even a mechanic, and I couldn't stop watching!!
Great video
1.theory of operation
2.review schematics
3. I.d. all players relays,fuses,module, control
4. Go in with scope
5.prove the fault
6.duplicate the fault at will
7. Correctly ID the root cause
8. Verify fix
Great steps and great repair
Detailed troubleshooting is the key here and your professionalism is awesome. But the phrase, "like tossing a hotdog down a hallway," was the culmination of it all. Give us some more stuff pls.
Best on the tube! You take us through every step in your thought process . Thanks for keeping me glued and making the wife go to the other room to watch her shows.
Great video and I enjoy the breakdowns of your diagnostic strategies. Keep up the good work.
Thank you!
Dang good job, this is what I like to see. Someone that takes pride in their work and troubleshoot a problem instead of replacing parts.
seems like you are a very good mechanic and trust worthy. Keep up the good work.
You really went into detail .Not many would have taken the time to hunt that problem down .Good work
You are a great technician and honest to boot. Wish you all the success you deserve.
Thank you!
This video is one of the best diagnostic videos I have ever seen.
Thank you very much! I'm glad you enjoyed it!
Impressed with the precision and knowledge applied to the troubleshooting of the problem, congrats! Job well done!
Eric, excellent video excellent diagnostics. Thanks for showing us your diagnostic procedure and walking us through the schematic. You would definitely make an excellent instructor. Have a good one and once again you produce excellent informative videos from start to finish. 👍👍👍
Love this guy. The antithesis of your professional parts changer.
Brilliant. Troubleshooting is an art of persistence and deep thought.
52 years in the Auto Repair Industry, as a technician/shop foreman/service manager, this is how it is performed professionally, well executed!!
Once it died after a few bumps I could tell it was wiring. But this video is more than helpful for a proper diagnosis of this type of problem. Crazy it was actually the connector. Thanks again!
Grit and determination will win the day! Great job in the diagnosis.
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.
Thank you Eric. Great job. Have a blessed and safe week.
I don't know what to say! Outstanding! I have a silly question for you: I didn't understand about your explanation why the fuel pump was not the responsible. thank you for everything!
Thanks for sharing. Love the way you explain things as well as showing the diagram and going through it really helps. Thanks
You do very thorough work when investigating problems. I wish more mechanics had your work ethic.
Enjoyed your diagnostic approach, great video. Thanks for doing the job one handed so you could bring us along.
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. Keep up the good work. God bless
I really like your approach for solving cases. Well done!
Just saw your Video. My 2011 Tundra stalled 2 miles from my house while my wife was transporting her horse. Thank you so much for educating us with your step by step approach to diagnosing the issue and rectifying it. It indeed is one of the best videos I have seen on any subject. I will be taking my truck to the shop, but at least I will be able to discuss the issue with them with some knowledge of the problem area. Thanks again!!!
You are amazing. My Tundra cut out while driving today which led me here. Now I’m just wishing / hoping my mechanic will be as thoughtful. Awesome video!
Bro you are good at your craft thank you for everything !!! Your work and dedication makes costumers feel good about doing business with you people like you are easy to find because of the passion you show about your job thank you !!
Awesome video! love how you breakdown your strategies. Very impressive work! Thank you
Excellent teaching diagnostics.
Great job as usual.
Thank you

Also a retired tech with 50 years automotive.
Intermittent problems are difficult to troubleshoot at times...You did an excellent job in finding this one...
Well done, sir. This is a classic case of "someone's been in here before me", and in this case, whoever put in the aftermarket gas tank mangled the pin on the fuel pump
It’s like a suspense, thriller movie on how you diagnose those problems. Good job man. Now I’m a believer on your channel and I just accidentally found it.
I was sitting on the edge of my seat the whole time, what an awesome video!!!!
Awesome! Thank you for watching!
That moment when you saw the dropout on the scope doing the wiggle test...YES! Nice fix too...no parts required, just some agile arms haha
Thanks!! I was determined not to have to drop the tank lol
@Pine Hollow Auto Diagnostics 🖕🖕🖕🖕🖕🖕🖕🖕🖕
Excellent step by step diagnosis, well done !!
I always learn something new with every video I watch from your channel. You've been of a lot of help to my career too.
It's a blessing being exposed to your channel.
I'm so glad that you made this video, because I had a wire issue with my tundra sr5 fuel pump wiring, also... stay safe and keep up the good work 👍👍
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!
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!
This was a beautiful diagnosis! Well done!
Just came across this cat’s channel, and I must say, “this dude is a wiz,” and I don’t say that lightly. I’d gladly pay for his services because clearly he’s earned whatever he charges. ✊🏼✌🏼
People fucking with stuff and taking there vehicles to the cheapest person or a friend is the worse thing you can do ,quality is expensive. Love seeing good work ,excellent job my man . You earned a sub . Thumbs way up
Excellent trouble shooting as always. I really like your videos, looking forward to more.
Thank you for taking your time and making nice case study , cheers mate “ uk “
Advance Level Diagnostics at its best... like a champ bro.Great diag 👍🏻🏆
Holy hell, no dealer or mechanic shop would've diagnosed that bad terminal connector. Great job!
Thank you!
Tempo the dealership new fuel pump/ and wiring harness $$$$$$
Excellent videos. Thank you for taking the time to make/edit them.
You are master of wire detection man. Great job. Very interesting.
Mr Eric this video blows my mind you are super good at your job as mechanic as level 10 the best of all you deserve better 👍
Nice job!I like your diagnostic approach.
In heavy commercial business i come across pin fitment issue all the time especially on aftermarket stuff
I learn so much watching your channel... keep up the great work!
I just started watcing your videos and I must say. AMAZING!!
Great persistent detective work!
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!
Very thorough and methodical, great job. I wanted that transfer flow tank for my tundra but now I think I’ll just leave the stock tank on there, never had problems. I can always buy rotopax fuel can jug things and that’ll be my extra fuel.
great video again! your persistence paid off well done
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!!!
Great job my man. Thanks for sharing knowledge and the right way of doing things. God bless.
You are so awesome , you and scanner Danner are my guys I tell everyone who I know wants to further their skills to watch thank you so much for your knowledge you share......
great job Eric very good diagnostic procedure one thing i can recommend is using a load substitution device ie sealed beam headlamp in place of fuel pump when you had connector out to get current flowing. All the best to you please keep em coming
Excellent video Eric! Very well explained and nice find on the connector. Thanks for sharing 👍
Have one of those tundras! They now have a recall for the fuel pump 😳
Yeah.....was a bad design.........every car compay has its flaws.......this one the just put and apple on an orange when designing it....
That was freakin awesome. Well done Sir!
