This is the kind of information people will pay big money for, gotta love someone doing it on KZbin to help everyone.

[@robertmorgan8536]

Amazing! You've raised the bar on KZbin instructional videos. Thank you.

[@joetappe6116]

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.

[@bengrillet]

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.

[@mathiasdamsgaard4913]

I Dont really comment often, but just know you helped a Scania apprentice a lot. Thank You from Denmark !!

[@myndcrym1]

What a great presentation. Clear and concise. You sir are a great teacher!

[@hunterjackson2651]

Great Video! I am inexperienced with Diesels, this video is actually organized and informative while not oversimplifying stuff. Keep up the great work man!

[@m998hmmwv7]

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.

[@RockinBarBRanch]

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!

[@garyjones783]

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!!!

[@silas8573]

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

[@lachiecollins7914]

Awesome easy to follow lesson, I understand fuel delivery of a common rail in 53 min amazing dude!!!

[@garymorrison4675]

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

[@codysautodiagnosticsprogra8706]

Excellent work Chris!! Absolutely love your knowledge and presentation. Keep up the great work.

[@ScienceOfDiagnostics]

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.

[@brunobarrie6089]

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

[@kevinmartin9432]

That's a better explanation of the system than any of the courses I have ever been on 😎

[@winstonhall557]

You’re Absolutely articulate . Would make a great teacher. System well explained.

[@jundelacruz7641]

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!

[@Ed-ip2sg]

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.

[@ryanblankespoor7428]

Thanks for making this, relatively new to diesel and working as a tech in the field this was very informative for me.

[@rayocaballo6122]

What a great video passing on knowledge is the greatest gift you can give

[@agde0968]

Thanks clear concise and also gives a clear understanding of what you maybe undertaking!

[@anywaysamhutsa]

the simplicity makes it easier for one to want to be a diesel mechanic.

[@jamesminnock7780]

Very informative, thank you for simplifying it .so much information out there .

[@johnshere4922]

Watched the video in full very good explanation of the total system. I can tell you are not reading from a book and got experience. Thanks, J S.

[@NewLevelAuto]

I know you'll wonder how I finished the whole video in 42 minutes ... and the answer is 1.5x speed 😁. Great video man. I even learned a few things

[@dreece2000]

Needed this simple comment.

[@glenquagmire4232]

Played it on 2x speed

[@bonjourmobilecardiagnostic7043]

That was a rough draft ???? Wow! Excellent video, thank you!

[@georgevesely1314]

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.

[@stuungar3390]

Yep, very thorough

[@mamadikmbajobajo7903]

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.

[@padraiggalvin2807]

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

[@richlee5578]

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

[@gregford5991]

Excellent video, well done

[@ebutuoyssa]

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.

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..

[@heatmizer9172]

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?

[@anthonylangit82]

Awesome video! I'm working on a JD350G and I'm experiencing issues with the fuel system. The engine sound like its running off 5 cylinders. I checked the fuel supply at #1 port at the rail and no fuel was coming out. I pulled the fitting with the spool and spring and cleaned it/checked the movement. The spool and spring seemed to be fine. At this point, I'm thinking the rail or the injection pump pressure regulator might be causing the issue. Have you experienced anything similar to this problem?

[@rednutflyfishing8795]

A Very nice video Christ .Which system has range rover vogue 2002 3 liter diesel ?

[@londzale3163]

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

[@johnrafferty3682]

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.

Thank you for the education.Please I have an issue with my 2013 Jeep Grand Cherokee CRD.I need your help

[@intofire112]

Thanks very good info.

[@0000stuart]

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 ?

[@keshwannaidu3943]

Very well done 👍👍👍

[@radnasirhill]

really good. Thanks

[@nadiasyedxx]

Awesome Video and illustrates very well how important the fuel pressure is. Hence I want to monitor the fuel pressure of my CRD. Where would I hook the Fuel pressure gauge (e.g. from Defi, AEM aso)? Furthermore which bar range should the gauge support? Which gauge do you recommend?

[@madinahboy]

I have a Hyundai Santa Fe 2.0 CRDI, I got codes p0087, p1186, p0192, car stalls on higher speeds usually over 60mph, or when you floor it, I changed filter, fuel rail sensor, how would you diagnose this if its a weak pump or has fuel line leaks ? Its weird I swapped my rail sensor with my brother's car then put mine back in and it worked fine for a week then started stalling again when trying to go over 60mph, or on sudden acceleration

[@PaulCTownsend]

Well done thank you.

[@user-wq3nl8ql7m]

Hi. I have hyundai trajet 2005 diesel with common rail System It's hard to start except if I disconnect ect sensor or if I turn on condititioner or If It was so cold which as I notice ecu give order to pump to much diesel in these three cases I want to ask you about the next situation: When I turn switch key to ON position without cranking the lift pump work afew seconds and stops and during these seconds diesl pass the high pressure pump into rail and then to the tank through pressure regulator valve. Also diesel come out high pressure fuel pump relief valve to the tank Is that OK or tere's some thing wrong Note: after the engine start working then every thing is OK

[@trevormathews3873]
