      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.

    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.

    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

  • @ebutuoyssa
    @ebutuoyssa 3 роки тому +1

    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.

    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

      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!
