Thank you for this information..

thanks tony.

great presentation tony thank you.!

Up north we do it because it’s not uncommon to have -40*f to -60*f days in the winter. (Just becomes a habit) 😅 also was taught it saves wear on starting components/glow plugs etc…

Hey! Aldo Abastta here, I’m Rafael Abasttas nephew from Laredo. I’ve went to some of your classes too when you were teaching up here at Central Motive Power back in the day in Denver. Funny to find you on UA-cam I was doing some diagnostic research. Rafael passed away in 2020 due to COVID, I don’t know if you heard, I’m sure you have. God rest his soul. But we’ll have to catch up next time your in Denver teaching or something. Still wrenching and working on diesels with my dad Marco. We do a lot of programming and diagnostic repairs.

Ty😊

My mileage was at 143,000. Other people with the same problem usually goes wrong at about 150,000.

This happened to me yesterday in the middle of nowhere Wyoming, on my way to Utah. It told me to service def system. Then about 5 min later came on and said I had 150 Mi to go. Then I pulled into a Loves started making phone calls looking on UA-cam and found out the (Diesel Exhaust Fluid injection pump) was the culprit. It was a pretty easy fix but you have to climb under the truck and it's connected to your exhaust. I had to order it to O'Reilly's and pick it up the next morning. Fixed it in the O'Reilly's parking lot and continued on my way, the code cleared all by itself about 50 miles down the road. My advice, once you see this pull over start youtubing the problem and then make your plan. Do not keep driving thinking it's going to go away cuz it won't. I tried to unplug my battery terminals that problem was still there no matter how long I unplugged them. In my eyes it was a blessing that I had 150 mile warning to figure out what I needed to get done, because I was pulling a 40-foot trailer and that would equal to a huge tow bill.

Why no class action law suit? Stupid dangerous to force a 5 mph limp mode, maybe 50 mph. Imagine beeling stuck traveling in desert or snow country, 5 mph limp mode could be lethal.

Hello Tony, thanks so much for the great presentation! Nice diagrams and clear delivery! I am in the midst of replacing injectors on a 2004 LB7 with only 94k miles and there are two things I would really appreciate expert advice on: 1) On each side, the rear injectors had a load of gritty crud at the inlets, and corrosion outside the metal/metal sealing interface. Fairly clean at the front injectors and no corrosion, but both symptoms progressively worse towards the rear. Do you know what this would be from and how to protect against it? 2) I would like to leak test the installed return lines. I have seen a nice video of replacing the block banjo with a special one that allows the line and 4 injector return connections to be tested, and this does test all the line welds, but I don't have one and I would like to test the block connection too. The return line from the engine has the CP3 and the regulator on it ..... Would a vacuum or a pressure test be feasible on the line without leaking through or damaging those? Thanks so much for your consideration of these things.

Thank you Dude!!! I can always find what I'm looking for on the internet. Finally found your video. I already know it's a shorted out led light that I installed but I couldn't find the fuse. I wish they would name shit easier to figure out. As soon as I seen the fancy blue dash lights on and the then the fuse blew... now I can finally go to bed 🙂

Thanks for you patience and knowledge of repair vehicles you are a truly professional master ❤I would love to work with someone like you in a shop

No amount of maintenance is going to prevent. 1. Turbo Coolant line in the valley. 2. EGR cooler from cracking

Simply a poor designed engine So many issues... Coolant Leaks in $$$$ places Over Soot Crank Flex 250,000 made, 50,000 failed. Shame as when they run, they are great

Im working on a 2006 ram 3500 that will start and run but I cannot get a scanner to connect to the ecm. Tried multiple different scanners. Nothing. This also is effecting the instrument cluster.

Spent days researching why fuel is being pumped back to tank and never creating pressure! Finally the best breakdown of a system without u tube nonsense Thankyou for making this video I'm finally clear where my problems may be.

So you can get foam in your rail

Hi,please show us how much exhaust leakage (not oil) is normal through the oil dip stick hole or engine oil cap

Let's talk mechanics. I don't need to know about your air conditioner.

P207F , still pops up for me and I have replaced the def injector with a napa part, had a complete regen that took an hour to do. Tested the def also and it was good. Had everything tested with the fancy tech scanners and all was good. Why do I keep getting this code?

Hey buddy , I need help how to change my oil pump on my 2014 jeep grand Cherokee , what do I have to do I’m doing it myself , thank you

Hello, I am having an issue finding an accurate diagram showing a location for all LML engine sensors. Specifically, I need the EGR temp sensor #1 for a 2014 but would like a complete sensor location list if it's available. Thank you.

I have been a Heavy Equipment Mechanic for thirty years and you have been the only person to be very detail and professional about the explanation between the ECU ,TIPIM AND OBD 2 Connector. Thank you very much.

Tony I just want you to know that the fuel system you're talking about here does not suck the fuel from the tank. What is happening is the pressure in the supply line is being reduced allowing atmospheric pressure to push fuel through the system.

well your dealing with junk

Hey Tony congratulations I have an issue wondering if you can help I’ll break it down as best as I can. I have a 2003 Duramax initially the customer had problems accelerating under load eventually the truck wouldn’t start so when I picked up the truck I was getting zero vacuum from the high pressure pump at the test port. Initially I replace the fuel filter with a ac delco but no luck so I cleared the fuel lines and remove the fuel pump to clear any debris. I didn’t find any debris but I did get it running eventually. Now it runs 4-6 vacuum, stays on and runs as long as I don’t do a sudden acceleration. Seems to bog down. My fuel pressure output is good till about 6-7k psi and then can’t keep up to the desired amount. After further testing I’m able to match the desired psi to over 15k with scanner at idle but not under load it dumps the actual psi under load. I removed the banjo at the junction block and only seen the high pressure pump bleeding out fuel not the fprv not sure what to do to finalize my diagnoses thanks in advance

We have a suspected air in fuel problem. The fllter head has been replaced with new OEM and still will kill once in a while then run smooth again. I recommended to my son to put a clear hose on the fuel return hopefully under the hood and run the clear line up under his windshield wiper to monitor while driving. Is this the easiest way to diagnose air in fuel? I'm thinking it HAS to be the issue but nothing is for sure so it'd be nice to confirm.

Congratulations! I appreciate you sharing your knowledge.

Thank you for suffering the heat to share this info!

I'm battling an issue with my 08 6.7L Cummins right now, of fuel de-rating under load, yet I get no codes. So in the worst method possible (throwing parts at it) I've made no headway. Under 60-70% throttle, 5th or 6th gear, say, climbing a mountain pass, commanded is at 22-23K. Rail Pressure (RP) is at same as commanded, then starts to drop as a little more throttle is input. RP drops to around 9-11k, and after 5-10 secs, derate counter increases by one, and the power is drastically reduced.. After about 30-40 secs, after backing out of the throttle, it will re-gain it's power and business as usual (until the next time). I've replace filters, fuel rail, RP pressure sensor, relief valve, checked crossover tube torque/re-torqued tubes, replaced in-tank lift pump, etc., but problem still remains. New Bosch injectors about 3-4 yrs ago, but only about 8-10000mi on them (replaced set because I had a failed injector). Any way, I get no codes, but cannot seem to find this fuel de-rate problem.. Thoughts? Thank you very much. Truck is tuned and has had same tune on it for 10 yrs.

With regards to the fuel cooler.... hot diesel is of course "bigger" in volume. This reduces power! We were testing the output power of an 850KW generator, but couldn't get full power from it. I leaned on the fuel tank and noticed it was screaming hot. Seems the guys had just dumped a couple of jerry cans in there since it was just a quick test. As the return fuel dumped in, it just kept getting the fuel hotter and hotter! Output was down about 15% at the end. Not a small amount at that level.

Hi I have a 2017 l5p have code p0191 they replace the connectors in the in injector passenger side also high pressure sensor but still has the code and low power you think I have to replace the lift pump truck has 169000 miles

Was the code p01c5 by chance i can't find any info on p01c5

Cant i just use a carter lift pump from a 6.5 and stand alone filter heads to keep costs way down?

Hello Tony, this is very informative, thank-you. I want to get a new fuel cap which has the pressure relief features built into the cap that you described to be so important. Would you please recommend a source for me to purchase that cap for my 2004.5 Chevrolet K2500HD Duramax 6.6L (LLY) truck? I have check the GM replacement parts, and don't see any that include the specs for the cap describing the pressure relief that you referred to.. Thank-you in advance, Bryan

I change the filter just have one but don’t start the only part I don’t change is the injectors that’s my next step the scanner says low pressure in common rail I don’t understand what happened have 2 months in the back of my yard need help

Hi I have 2007 dodge ram 6.7 cuminns I stop the truck for repair the head gasket and repair the cylinder head everything was fine and when I tried to start the truck don’t work I buy a cp3 fuel pump the pump of the tank cam sensor the 2 sensors of the common rail but no start said to low fuel pressure in common rail can you help

Can I swap a 2016 Ram 1500 ecodiesel engine with a 2014-2018 Jeep Grand Cherokee diesel 3.0l? Is it the same motor short or some attachments I could swap back from the old motor? Or is there components that may be compromised on the old motor that can't be easily swapped to a jeep 3.0 ecodiesel

Hola que tal tengo una pregunta tengo una vam con motor lgh duramax le puedo poner intectores lml ?

You rock - very balanced and good troubleshooting lesson. Thank you.

Useless. Just useless

Call Tony the actress pretty pretty sample, it's because the mother fucker chose to leave it running that's his deal and ask for waist and feel you're talking about a couple of pennies I wouldn't sweat it go enjoy your day top off your truck and take it for a drive, Jesus smh

I have a 2014 ram with the 6.7, it died on me going down the highway and now have a crank no start issue. I replaced the filters and confirmed my lift pump was getting pressure. My monitor says commanded pressure with the key in on position is 4641 psi and the actual is only 107 psi. Is it safe to assume the cp3 is bad or should i be looking at fca or rail pressure sensor?

Hi Tony, this coming from a previous ADS employer in Canada. Myself and my boss at the time were at your lly Duramax course (2004) in Indiana. Must have been terre haute as we went to scheid diesel extranganza afterwards. Glad to see you here on UA-cam! I now work for a municipal employer and have received basic EV training. I still treasure my days working with the early days of common rail. Ghalee eh...I remember it being big news hearing that each glow plug would have a trouble code,lol. Good times, thanks from Canada!

Low pressure in fuel rail after changing filters

I got the low fuel pressure code after changing both filters i think the truck got some air because it wouldn't turn on after i let some air out it cranked right up but started with the check engine light now once it gets to normal temp will loose power and wont go over 10 mph whay could be the cause for rthat

So we are still sending CCVgas or engine sewage into the filtered cold air intake to the combustion chamber to mix with the finely metered air-fuel ratio lowering HP and MPG

You talk too much. Get to the point.

Hey Tony how can I join in your next round table and how do I get hooked with your classes?

In the middle of nowhere in Urah, my truck says service def. A few minutes later it went to count down. Later, I had 20 miles till it went into limp mode. Stopped and pulled batterie cables. Made it to a Dodge dealership. They came back an hour later and they could not find anything wrong. Drove home 500 miles away. No problem. Twice this has happened to me. Ruined my vacation. Any lawsuits happening with this bullshit. No problems till I paid my truck off.
