"My Engine Shut Off and Won't Restart, but Why?" Question of the Week 1

[@bwalt44]

Great video keep them coming

[@DVNelson]

Love it! We appreciate your experience and insight. I know alot of places rush to tell you that you have a bad part with minimal to no actual diagnosing of the problem. Basics first, test, then parts. Kepp 'em coming!!!

[@yves8639]

That was my exact issue this summer. It ended up being a bad ECM. Diagnosis was made because all injectors were giving an error.

[@midevolgamingvortex8844]

Had a ford ambulance come in once 7.3 powerstroke ran terrible, guy went through fuel trouble shooting etc. Eventually found it was like 7qts low on oil, changed the oil and filled to the proper amount. Ran great after that.

[@Realtrucker81]

Great content Josh and I love the concept for these videos. My vote is to keep ‘em coming!

[@unwired1281]

I agree but be sure to follow up if you hear back on the outcome.

[@raulpereyra2817]

This is a good concept to triage the problem.

[@pauljordan756]

I like this style. Thanks for sharing your time and knowledge Josh. Much appreciated.

[@Jengoboys603]

#1 mechanic story from the driver is "it just shut off" last time it ended up having 2 smashed valves and a sleeve soo fucked up it ruined the block!

[@jerryplante4239]

I have a 3126 in the motor home. Near as I can tell it's the original HEUI pump. I've often considered buying a reman pump and throwing it in the basement for a spare. Now rethinking that. Thanks Josh!

[@Jsdiesel1776]

Hey man, I like these style video’s. I would like to see and would look forward to one every week.

[@AdeptApe]

Thank you for letting me know, getting good feedback on it.

[@Jsdiesel1776]

@@AdeptApe awesome!

[@coryridder1937]

I like this format. Simple and could be extremely helpful to someone in a pinch. I love watching and take something away from every video

[@partrickstowman8039]

Big fan of the question segment!

[@cew995]

If we were talking about a DT466 Navistar with Huey (spell check won’t let me spell it correctly)I would start by replacing the cam sensor. It goes bad and doesn’t throw a code. I maintained a bunch of these and I lost track of how many times I replaced the cam sensor on the side of the road. They would sometimes last years and sometimes only weeks.

[@dahltonguilbeau4354]

I just want to say thank you. Over the last 2 years I've transitioned from a career in nursing to farming. I've also acquired an RV with a caterpillar 3126 in it. Your knowledge has helped me a lot through the years. I'm replacing my 3126 injector cups this weekend. They have the cooper style sleeves. So that will be fun. I'm very impressed with Caterpillar and their parts/ parts diagrams online. To bad caterpillar doesn't make smaller agi tractors. I'd buy one in a heartbeat.

[@rickl6697]

Yes, more like this would be nice. Very worthwhile. So, on a Heui system, (Our motor home has a 3126E), if the oil pump suddenly stopped pumping the Heui pump would stop providing the pressure to fire the injectors and the engine would shut off and prevent the engine from running with no oil pressure. A kind of fail safe system. Thanks for posting.

[@abelgallegos2056]

Keep this new series. Great content.

[@fredmalito9869]

Yes, these are the videos we are looking for.

[@Gdone]

I like that you take time to read the email and post a response to give expert opinion how to diagnose the problem👍

[@WilliamLaakkonen]

Thanks Josh- I like this style video. Interesting and yes, we (I) did learned something. I hope you get a return on the effort here. Cheers

[@matthewzoelle9149]

I like this style of video, please continue to make them!

[@Burnsidef250]

Had a few 7.3s come in once, get into a hard pull and they would die but restart every time. 2 gallons low on oil. Mind you they only hold 15 quarts

[@ashley_morrell]

Keep posting them more videos of your troubleshooting jobs/questions of the week!!!!! You are brilliant and I wanna learn from you as much as I can!

[@richkelley5112]

I like this type of video Josh. All of your content is very good, and this style will be too. Thanks for all the effort you put in to educating us.

[@abouebiye4354]

Thank you very much.

[@davidwells9342]

Thanks I’m a practicing diesel tech and I don’t get a lot of trouble shooting under my belt it’s nice to have videos like this

[@420tagalong]

@AdeptApe i've been a sub of yours for a very long time an love tha vidja's. You have great content an very good knowledgeable skills on deasil engines. These little video's are very helpfull for some. Keep up the great work an keep em coming.

[@Daniel-xf7gr]

Great video thanks

[@camerson4133]

Definitely would love to see more of these videos

[@guyfranks4354]

Yes Josh, I like this style of video. I am eager to learn more about Diesel engines. Have you ever been to the CAT Proving Grounds in Southern Arizona? I used to drive Motor Coaches in the early 2000s and CAT contracted the Company I was working for to provide transportation for the New Models Showcases. I really enjoyed driving those groups then.

Enjoyed the video. Please keep them coming.

[@fiendgod1399]

Please keep doing question of the week! Love this idea

[@jrwhitehurst5411]

Great video. Would love for you to continue these.

[@michaeldunagan8268]

I learned a lot from your channel over the last few years of watching it and I'm so grateful to you. If I ever get some flushing cash, I got a Ben Franklin with your name on it. The video where you don't use a whiz wheel to clean the deck surface of an engine block but rather just use a scraper in a razor and some sandpaper. I took this advice on doing the valve cover gaskets on my 1999 Toyota Solara V6. There was some stain in the aluminum and I remembered your video so I didn't try to dig it out since it was flat and clean. I think it's wonderful you share your knowledge. I like in this video that you try your best to diagnose it but know that you can't pinpoint it without doing the checks.

[@AdeptApe]

Thanks for watching the videos Michael. You can find old videos were I am using a wiz wheel actually, but my opinions are always trying to improve on everything I do. Glad to have you along.

[@Mighty-Quinn]

I think this type of video is a good idea. I'd love to see more

[@darrencatenacci2737]

Like just about all of your videos. Generally quite informative and clearly explained on every subject.

[@garykirk1968]

I'm just beginning to finally grasp the concept of heui engines, I've replaced many a part on old Fords, but never REALLY did the diag. Knew some common failures and their symptoms, so could pretty well take care of small issues. However, I've worked on a metric ton of 5.9 and 8.3 Cummins so got really good with them. Now am working for a heavy truck and equipment dealer/rentals joint. So your videos are proving beyond priceless to help me further my own knowledge brother. I say, keep all of them coming man.

[@duaneb193]

I like this type of video - you sharing your knowledge is worth a lot to those of us that try to do all of our own work (I just hope that I don't ever need some of it with MY 3126). All of your videos are excellent and informative!

[@Steventhedieseltechapprentice]

I found your channel a few month back and I'm glad I did. Love your content and looking forward to the new series. Thanks for another video!

Hey, I like this style video as well.. used to work at a T/A working on the trucks coming in for repairs. It's been years but I still like to Keep up with anything I did learn while there even if you're showing me something new. My brother is a trucker so sometimes I can help him out with it when he comes to town on his runs across the country..

i agree with a electrical or ECM failure great tech keep doing this

[@BobSmith-mc7uq]

Josh helped me out once on a Cat engine problem, THANKS PAL! A mix of repair & question-answer videos works well. My 2 cents.

[@alexeckhardt5323]

I vote yes! This is a great idea for a weekly video and super helpful! Thank you for taking the time to do this Josh.

[@tedc6694]

Your starting to really fine tune your skills. Thanks for sharing

[@371508129]

I like learning new things. Good idea/job. Don’t have a 3126 but if I ever run across one that’s having trouble I now can contribute to the conversation.

[@oldpete3153]

My 3126 had a no start cranking situation 2yrs ago after no codes and everything else checked it was a crapped out ECM. $2600 later and away we go.

[@TheCRTman]

That sounds correct. We have a bus that randomly shuts off. It had electrical problems as well.

[@garrettboyle5892]

I would love to see more of these style videos! It amazes me how many people don't understand the HEUI injection system. I came from a 6.0/7.3 background so I am somewhat familiar. But I've had to help a few coworkers of mine troubleshoot to keep them from just throwing pumps at them lol

[@aerialrescuesolutions3277]

LOve this style of video, keep them coming

[@thedaddiii]

These are extremely helpful. Doesn’t matter if it’s someone working on one or a driver it helps create better understanding. Thank you and keep doing these!

[@abpsd73]

I'm not familiar with CAT HEUI systems, but I have done some work on IH ones. Had a failure with the same symptoms, the pressure regulator was failed/stuck open so pressure wouldn't build. You're right that lube oil has to be there or the HEUI pump won't have oil to pressurize.

[@greaseman83]

good deal josh keep them coming

[@bat__bat]

Yes good, easy to make vid format. Those damn heui pumps. By the way, you see Deboss just recently got his cat tree fitty running ok on that obs Ford. I remember you told him which engine config was the better 1. That was a sick project and the finished engine sounds great on the Ford.

[@AdeptApe]

I did, what a project that turned into. He makes pretty cool stuff up there in Canada.

[@norwcav]

Yes please. More of this.

[@iBackshift]

YUP...good changeup to keep it interesting. In my business I deal with these kind of troubleshooting emails every day. I have around 50 "canned speeches" as say there's about that many variations I have to deal with, then copy-paste and tweak the answer for the individual.

[@badgerpa9]

Great video. Be safe Sir.

[@notiangraham6600]

I appreciate this kind of video. Very helpful. Question was answered in the simplest form. Good work

[@adamgardner4213]

Good deal I enjoy trouble shooting and or thought process type of videos It provides insight beyond Stupid part failed

[@TedsGarage]

Definitely do appreciate it, especially as someone who's sent you an email (and received a very helpful response) that helped me out with my 3126 in the past. I'm not sure what percentage of your questions come from other 3126 owners, but given the popularity of 3126s in RVs that are now owned by people who do their own work, the more 3126 info I can learn the better off I am. Although you might not be happy about the fact that I'm putting 180 degree thermostats in mine, but there's a good reason for it! I promise! 🙂

[@thecat6062]

Thanks for considering doing this type of video. You can be sure that by answering one persons question you will be helping many more that probably have the same problem . Keep up the great content!

[@rustyshackleford842]

Good video Josh

[@mattmurdock4336]

I think it would be cool to see some videos related to common failures caused by age. The on highway engines are OLD, racking up insane miles and hours. There has to be "new" symptoms and incorrect diag tracing thanks to wear and tear.

[@rrnelsonjr]

I had a F-650 with a C-7 that suddenly quit running like someone turned off the key. I checked all the fuses under the hood and under the dash and all the fuses were good. I had it towed to the local Cat dealer and after a few hours of diagnosis they found a bad fuse to the ECM. I explained to them that I already checked all the fuses under the hood and the dash and found that they were all good. The CAT dealer explained to me that there was another fuse in the battery box that was for the ECM. A had a tow bill and 3 hours labor just to find out it was a dollar fuse in a location that I didn't think it belonged. There was another fuse in the battery box for the Alison so I don't believe these fuses were someone's hack job. I believe Ford placed them there.

[@firemech911]

Most trucks have fuses in the battery box for the different ecm’s

[@rrnelsonjr]

@@firemech911 The Freightliner I currently own has the ECM fuse in the fuse block. It is the same thing with the Peterbilts and Kenworths family and friends own. This F-650 is the first time I have ever seen that.

[@firemech911]

@@rrnelsonjr Cat,Cummins,Detroit used to require that the OEM’s put the unswitched power for the ecm in close proximity to the battery box some of that when they started switching over to multiplexed systems but I still find a lot of them in the battery box.

[@rrnelsonjr]

It just really sucked for me because I never experienced that before. I learned something new that day but I learned it the expensive way. When the Alison acted up on me a couple years later I knew where to go and it didn't cost me a tow that time because that fuse was in the battery box as well. It only cost me a dollar fuse to fix it that time...lol.

[@firemech911]

@@rrnelsonjr I had a truck in the shop years ago I don’t remember the problem but it took me a week to figure it out it had a crack fuse in the fuse block it would carry enough load to light a test light and read voltage on my meter so out of desperation is visually checked the all the fuses with a flashlight for about the umpteenth hundred time and finally found a small crack in the fuse I couldn’t believe it I kept that fuse in my toolbox for years just because it was that unbelievable

Great video!! Do a video on an atmospheric pressure sensor on a C-15.. what it does, how it works?? Woke up one morning in SD, -5 out side and a check engine light on,checked the codes--- atmospheric pressure sensor. Truck still was running, bought the sensor, stared to change but the plug looked different, so I stopped, check engine went out????? So I don't know???
