I've been an automotive, light duty diesel technician for 27 years, plus raised up in the car business. Been doing Diesel work for the last 12 years of my career. This video Is Awesome. Very Basic and a great video. I enjoy watching People that are intelligent of this kind of work.
I totally agree! I entered the world of mechanics as a young boy as early as I can remember watching my Dad. He built and drove his own racing cars. He ran dirt, asphalt flat and grade. Before NASCAR he built and ran drag cars right out of the Army. But decided on NASCAR for the longterm. I was always in the shop watching, learning and taking things apart and figuring out how to put them back together again. I'm 57 years young now and have never taken a break from the mechanical world. Over the years I've achieved a lot of goals and became a self taught professional mechanic with a good reputation successfully owning my own repair shop. I can definitely spot another professional when I see one and your very intelligent. Outstanding job on this video explaining procedures to follow in diagnostics troubleshooting techniques. Thank you for contributing this video.
first time i do comments on video , this guy is a master , i hope will be able tomorrow to fix my skid steer that is cranking with no start , great video .
Absolutely superb guide to the system. So clearly and patiently explained that, even as an amateur DIY mechanic, I was able to get to grips with the information and get my head around how to approach a diagnosis of my crank-no-start problem. Useful even just to help me discuss a diagnosis with my mechanic. Real impressive. You are a natural teacher, respect.
Good video of explanation. You gave me a flashback on those ford 6.0’s (sick O’s ) with those high pressure oil pumps. .. 1988-2015 on those diesels … got out of that and glad I did.
Great Video! I am inexperienced with Diesels, this video is actually organized and informative while not oversimplifying stuff. Keep up the great work man!
you are the professor bro. thank you so much for making this video. i'm a non-mechanic trying to resurrect a cummins/onan generator and this video gave me the jump start i needed
Loved your discussion of the overall workings of the system. I have a common rail 5.9 Cummins and it is now 20 plus years old; therefore, diagnostics will being be more and more important. Thank you!
Excellent way to present the number of possibilities involved with the diesel fuel system. Enjoyed your sensibility and respect towards the art of the engine vs the vulgarian F bomb bad boy way. Classic!!!
Wow! I feel a little less stupid knowing about diesel systems. I've watched this video twice and made plenty of notes. I reckon by the time I watch this video for the fifth time I should know something. I'm looking forward to another basic diesel education. Keep them coming. Great work Chris.
Thank you so much for posting this video in such a way that I could understand and use the information. The time it took to make and the completeness in pictures and explanation is priceless. Again thank you very much for your time and help.
Thank you for your very clear explanation about fuel system. Really enjoyed & appreciate it! Very professional just like you're a professor in a classroom. I am from the Philippines. Mabuhay ka!
Some people act like they know what they're talking about there is no doubt that you do and that you are the man I'm so glad I found you saving me from a nightmare of bad Direction I will be subscribing
Wow just got to say really great video. you covered so much here and in such a good systematic way and easy to under stand. Only two things i could add here, for a non starting diesel engine are 1 cranking speed which you covered by saying battery but also starter motors can be the problem. but some diesel engines need a minimum crank speed to start. and 2 is EGR valves, if these are stuck in open position they can stop engine starting as the air/fuel mixture is compromised/disrupted. Thanks again for the great video
i've been looking for my perfect learning skills through any way to go but this guy's page gab my full attention (sience diagnotic is my best and easy point to learn fast as well too) thank you
I appreciate it Cody. You've been working hard to keep me motivated and putting out at least some content and I appreciate it on behalf of the viewers. I definitely need to focus more on getting good content out to the people. I'm not good at many things but I do enjoy passing on the tiny bit I know if it helps people.
@@ScienceOfDiagnostics hi im in ireland i have fiat ducato 2.8 jtd year 2002,new pump in tank new fuel lines new batteries and starter,i cant get fuel at the rail but she fires right off with easy start have you any ideas
I am very mechanically inclined. Never owned a diesel till i got my 04 gmc sierra 2500hd duramax lb7 4x4. After having the truck for around 5 years now. You are correct on how they are not all that difficult to work on. Its in my opinion easier than a gas vehicle.
Great info. I have the t1n 2005 sprinter with low rail pressure . Thanks to your video i have a better understanding of the fuel rail system and have made a list to narrow down the problem
It is indeed a fantastic lectures. My coming across your lecture coinsided with having fault of starting failure with my 2010 hyumdai tucson diesel. Your lecture enable me to successfully did a lot of test. Where I am now to know whether or not my rail pressure sensor/pressure regulator are good.
Science of Diagnostic KNOWLEDGEABLE Great tutorial brilliant video thank you very much helpful video Science of Diagnostic. Pauly 's Auto was right about this channel thank you Pauly 's Auto From Nick Ayivor from London England UK 🇬🇧
Excellent presentation. Out of all the wealth of information you just shared -for me- the key to the diagnostic kingdom you mentioned is- "If your low pressure side isn't delivering sufficient pressure, the high pressure side can not make it's required pressure" (paraphrased). Jumping right into injector failure mode rather than considering first that the issue may be something as simple as an undetectable air leak, will destroy your credibility and break your business/wallet.. I replaced my OEM (piss poor and leak prone system) with a positive pressure (lift) in tank component and a primer blank out unit after 3 weeks of spanking around with every connection and potential air leak -with only 1 one possible leak point found. When you do the math-it's much cheaper to just junk the stock fuel delivery system, and upgrade to a quality USA made lift system. Final diagnostic note... This vehicle was found to have lost the CP3 lift pump capability putting it in a "no start condition". Problem was overridden via the lift pump installation. Thank you Sir.
Best explanation ever wis I’d seen this video before I had trouble with a diesel ford mondeo UK crank but no start I ended up putting it into a garage who systematically ripped me off never got it running and I’ve been working on cars for years 😂but mention diesel’s over here and you can see £ signs in their eyes but really when you look at a diesel if it’s not running 9 out of 10 it’s the fuel thanks for the info
Great vid. Thanks a heap. My diesel 4x4 is Crank no start, now I have methodology for figuring out what’s up. I suspected fuel but nice to know how and where to look / trace the flows.
Great video. Lots of really good and useful information. Well explained. I haven’t bought my truck for towing an RV yet. Would like the diesel in the mountains. Not as as scared as I was. Thank you.
Dammm!~ some people are a pleasure to learn from... somewhat rare! You are one rare gem! I have a 2010 Chevrolet 4500 mini bus/shuttle with a 2011 running train factory installed (the LGH) and it says on the sticker it is a DI(Direct Injection)... I may not have a rail type... I have no idea! I have to snoop and get more info, clues! I am but a noob! UPDATE: after snooping I now know that common rail is direct injection since quite a while back..
Sincerely, Impressive presentation sir.1979 John Deere 2840 -the Gifted-WorkHorse I am now (only now, after 20+ years of use/abuse) am forced to look directly in the mouth. Suffice to say, you saved my ass - it's cold in Michigan February. It's colder without my tractor. Thanks man. Sincerely.
From my experience, trucks that have primary fuel filter and a secondary fuel filter or fuel water separator never seem to have fuel related issues. As long as you change them after every pm service you’re good. It’s the trucks that only have one filter or separator that have a lot fuel system problems
Great presentation. There are after-market tool companies that sell a mechanical common rail pressure gauge with fitting, hoses and plugs. Are there any reputable tool companies like Snap-On or Mac that sell a similar test kit. Something about a Chinese $300 test kit and over 20,000psi plus doesn't add up.
This is the most informative in-depth video on diesel diag I have ever seen think you so much please keep doing what your doing. Do you have any in depth DEF, DPF, SCR diag videos?
What an incredible video mate, not used to diesel engines but this has taught me LOADS! I'm having a Crank - No Start Issue with my Iveco Daily 2.8, watching this video makes me wanna go further back down the fuel system and re-check Low Pressure...which I assumed was fine, as I'm getting fuel upto the Common Rail...but maybe still not enough pressure!? Thanks man.
Just thought I'd update: Finally managed to get my van started!! This video was a huge help - turns out I just needed to bleed the air out from ALL of the injector inlet pipes - (I'd only checked fuel was "reaching" 1-2 of them). Pipe No.3 had a lot of air, finally pushed diesel through and it started! (Note: I think I'd drained the fuel lines via the return pipe, by running my diesel heater without the engine running)
@@Automotiverecoveryuk Depends on the vehicle mate, I think some Pipes are not meant to be loosened more than once, so check and be careful...but, I just loosened the pipe nut on each injector (not the one on the common rail, as air rises in the pipe, so best do the highest one), 1,2,3, then 4 etc. Loosen them, then crank/try to start the engine for a few seconds - air should come out, followed by a squirt of diesel, then quickly re-tighten the nut. Repeat for each injector pipe until all the air is released. Good luck!
I'm a new Diesel truck owner, thank you very much for simplifying how the system works. I'm having issues with my truck only starting after being plugged in, if I don't plug it up over night, it will not start !!! By chance can you tell me what may be the problem ?
Sir you’re a great teacher ! How about teaching us onhows the flow of diesel fuel in isuzu trooper w / 4jx1 engine works . So many trooper owner may get happy if you can do that , because we’re getting too much hard in trouble shooting w/ this engine every we opem up the diesel line . Like replacing fuel filter after that we’re getting to re - start it up , so please help us ! I’m from the Philippines thanks a lot & God Bless You !
Hi. I have a CP1 high pressure pump on 2.8 hdi jtd pickup. To get it started I have to loosen the top head which carries the fuel cut off sensor then tighten it up after turning on ignition.
Thanks for the video . I've got a 2013 fuso canter 3c13 with low fuel pressure . It's now in a garage & there struggling to fix it . The truck will only start - run when the fuel pump pressure regulator is disconnected . At all rpm's above 1000 the fuel pressure is ok . It's got a new fuel filter . At the moment I think maybe the low fuel pressure sensor on the common rail may be faulty . Any ideas please ?
I grew up in a Garage father ,uncle granddad all Mechanics. Sorry now were called Tech's . I remember my Dad teaching me and he always said books are good, But if you can't visualized what going on and have a good mental image of how its working . you will never understand it ! Great video !!
Great video Chris. As always I appreciate your thorough attention to detail. I didn't know you were CAT certified. Were you more on the truck side of things or did you do off-highway? Looking forward to the next part! -Z-
