WOW this was a cool case study, Bernie! Now my question is why that car needed a fuel line repair to begin with? And that is the biggest glass beaker I have seen in my entire life haha! You're a mad scientist, Bernie!! :)
Probably because the "brakes and suspension" mechanic used his "trusty ol pry bar" to help himself when R&R one of the 2 new high pressure fuel pumps that were installed(just like he damaged the harness for rail sensor, when prying to change the alternator). Probably when was using this mighty suspension repair tool he damaged the line. I wonder when pump is working against restriction(also a clogged filter) will the amps for the pump go up ? i think yes. 🍻
@@petar443 I often wondered why they dont put a light on the dash for fuel pump amp draw to save a pump if filter is clogged or another restriction should have been done years ago
Trolls and/or haters. Try to find one youtube video with over a thousand likes that does not have at least a few dislikes. The dislikes are most often not real. Look at our world...'nuff said.
This is, by far, the most impressive diagnostic video I have ever seen. I can assure you that 99% of all mechanics don't come close to this. Most everyone is a part thrower by comparison. I wish all mechanics learned things at an engineering level.
A simple fix can be the hardest to find. Bernie’s though process is amazing, all very logical stuff but I would never think of them. Absolutely brilliant, thank you so much Bernie 🙏🙏👍
Absolutely fascinating! My eyes are widened to what all can be seen in a waveform! Where would we be without people like you sharing this? I am so thankful to be able to learn from all your time and effort and years of experience Bernie! You are helping to train the next generation of techs who want to get the job done, and get it done right!! Much appreciated.
2 HP pumps, 2 LP pumps, 1 PCM and 3 shops is astounding. Superb job Bernie, showing us how to test and not guess. Thankyou for taking the time to make it for us all so we can learn from you
Top notch diagnosis. I always think of your motto when working on a tough car. Get the data, interpret the data, data drives the next test. Listen to the data!
every time i watch you work, bernie, i re-learn information i forgot and learn something new that i didnt know. i love your passion for finding problems in cars. i can relate to finding an unexpected issue and going "thats cool"
Bernie, words fail me, but not you. The way you gathered data! The 'understanding' from the data! And the discussion of DC motors, using powers and grounds is priceless. I would say 'one of your best ever' but heck, they're all good. So, when the high pressure pump output dropped did the hp pump go into cavitation because of the low input pressure?
This poor car had parts thrown at it all because of mechanics who worked on it creating the problems. Not sure why anyone would try to repair a fuel line... I can't imagine the liability of your repair failing. Should have just replaced the line the correct way the first time. One crazy case study. Thank you ! 💪
I like this channel because Bernie consistently uses the scope and explains in great detail which really drives it home. It's the understanding of mechanical force that creates the wave that he knows so well. This is better than watching a movie.
Can you imagine having Bernie as a instructor from day one like the 1st day that you started learning anything to do with mechanics or automobiles ? Almost everything that he talks about is stated as an absolute because he knows Almost everything there is to know about cars. Anyone that has been in the field for a good amount of time knows that there is no way Humanly possible to know everything about every car, But I think that Bernie knows as much as anyone could possibly know about Automobiles. I just keep coming back to how many things I learned the hard wayAs a junior tech... How many things I learned That were wrong and I had to go back and rewrite this information in my head which is not easy to do. So I can only imagine if from day one I weren't everything the correct way and had everything explained down to the smallest detail on theory of operation, why components fail the way they do etc... It blows my mind every time I watch one of his videos the amount of information that he has Is incredible. I guess that is the product of i think about 35 years of experience put into a 30 or 45 minute video. Thank you Bernie for the time you put into these videos, and thank you for your contribution to the automotive field as a whole. I know there's thousands of techs who have benefited from your instruction and knowledge.
the little demo set you starting at <a href="#" class="seekto" data-time="2160">36:00</a> this is why i love this channel. you can feel the passion for it and it makes learning much more exciting
It seems safe to say that, since the fuel rail pressure sensor was dropping out, the ECM was making up its own value for the fuel rail pressure at times, based on other data and what it "expected" the pressure to be. Just shows that scan tools can burn you sometimes with substituted values if you don't look deeper into the problem.
Bernie , du bist ein techniker vor dem ich hohe achtung habe. Deine diagnoseansätze sind genial.dir alles gute, vor allem gute gesundheit , immer.dein kameramann muß noch viel lernen.gerade spannende parameter von dir bekommt er nicht gut abgebildet.bernie bleib gesund, das ist das wichtigste!!!
These guys make money sponsor ships and ad cents. Things are so expensive now after the pandemic no one can afford to work for free! Thanks for the awesome video for sure!!
Iam glad that 40 years ago my instructor only tought me 1 thing and that was to exhaust all the basics twice before installing parts Guess they are not teaching that anymore
What a great diagnostic lesson! Few techs have the knowledge or skills to troubleshoot electrical/electronic issues. A scan tool is not enough to always pinpoint where the problem lies. Until we know how to use a oscilloscope we are just running around in circles. You showed how the other shops simply assumed that it was a component that was at fault. Your logical approach was able to verify what was working properly & what was not. A great video that I learned a lot from!
Excelente caso de estudio , profesor usted es una ciencia en diagnóstico, profundos conocimientos, sencillos y humildad, gracias por compartir sus conocimientos con el gremio , mil gracias profe !!!!!
A really great case study Bernie and would look forward to you doing some lectures. It wouldn't matter what the topic is because you're a great teacher and would make any subject interesting. Have a great week!
this is incredible, the amount of work put in to teach and demonstrate these concepts thoroughly is beyond praise. every time a new video is made the world becomes a better place. imagine how many people will learn from this, including myself. never really looked at pump rpm difference with engine idling vs under load, only average current.
Awesome!! Great lesson at the end too. You never cease to amaze me. You definitely know your stuff. To diagnose the restriction from the driver seat is inspiring. I'm in awe!
Awesome diagnosis. Bernie it will be so helpful if the Escan graph mode had a cursor on all the pids. One that you can move back and forth to see the glitch, and if you move it on one pid it moves it in all on the same spot so we know that at that moment of the glitch what was the values on the rest of the pids.
Mind blown...also can't believe this is free to watch and try to capture an ounce of knowledge from...well, perhaps the most knowledgeable mechanic ever? Love these vids...especially the "this car has been to several shops with parts replaced, now it's time to actually fix this vehicle".
Great Case Study…If the first shop just went back to basics and checked if the high pressure pump was getting what it needed, conduct a pressure and volume test like you did, well, I don’t have to say it. I started my career in the late 80s when we did a fuel volume test at the carburetor, rule of thumb was 1/2 pint in 15 seconds. Overall, the other shops pain was our gain though.
Bernie, you will be AWESOME in my book always great tool and what a teacher u are in this profession thanks for sharing ur knowledge really appreciated as always and hopefully one day will be able to purchase the ATS ESCOPE ELITE love the tool just by watching you how to diagnose really impressive thank you from Ontario Canada.

You sir are the Sherlock Holmes of auto diagnostics. Killer diagnostic scanner tool also. Good job. I have 2012 Veloster with same engine that is running rough so I watched vid. Hope your charging a premium for your rare skills.
Very interesting diagnosis and explanation :) I have 2016 Kia Rio as well, but mine is Euro spec 1,25 litre 5-door Hatchback. So far no problems, bought it new back in 2016.
"Properly diagnostic".. mechanically I understand what you're doing, but I'm not familiar with the lingo.. fuel trim.. lamda.. etc. I really liked the test at the end of the video.. very informative.. your a great teacher Mr Thompson..
Always waiting for your videos. it knowledgeable. keep those videos coming in . Great teaching knowledge. and bless you for sharing your taught process .
I love this great technical learning vid. I am miles behind your expertise but with common sense and a Good understanding of the combustion process I always win and solve the problem. I thought looking at the data you would find blocked or damaged fuel filter or crushed fuel line.
Just an idea that came to mind just befdore <a href="#" class="seekto" data-time="648">10:48</a> , might be worth programming the button on the pen to do a "start/stop" on the scope so you could just tap that and viola! Great video as always! :)
Very good case study, you awesome MR BERNIE, thanks to teaching us, we always learn something from you, thinking to get your scope, looks very professional with a lot of things on it. once again, thanks for sharing 🙋🏻♂️👍
Oh boy, great case study. Did the shop inform you of the history behind this vehicle ? And if a car with a fuel pump control module happens to come along maybe we can take a look at that . Thanks so much for your time. I realize you are demonstrating your product , but you go above and beyond by explaining the logical diagnostic process that leads to the correct repair. Again thanks.
flow/pressure relationship showing there. anytime you have a pressure problem you NEED to test flow. same for hydraulic systems on equipment. nice to see how the scope worked to verify prior to physically checking flow.
Great video love it. What I want to know is how pressure wasn’t checked on the low side at the fitting while driving earlier in the other shops diagnostic process. You could see with a scan tool the pressure leaving. Start simple check supply. Great diagnosis and great lecture.
