    Nice job and well explained step by step. I actually have my 2016 GMC at the dealership getting done now. My truck shutdown on me and I changed the fuel filter but couldn't get it to start back up, so the dealership said the injector pump had gone out. Wish you was in my town! Thanks

    I know very little I did my thermostat on my 2011 lml and that was a sort of scary project for me. From what I hear the cp4s are doomed to fail, not if but when. The best route is to do a cp3 conversation. That's number one on my list (when I can afford it) wish I had the stones to do it myself. Awesome video man , although it may give me a false sense of my abilities watching how easy you make it look 👍👍

    Does it matter what injector goes to what cylinder as long as you keep track of the numbers

    What about contamination in the gas tank, supply lines, return lines, and filter housing? Were they flushed?

    Hey man. Great video. Just what I’ve been looking for! I’ve got a 15 LML. I’m about to try this install with a CP3. What do I need to be able to program the injectors to the computer?

    I have a 2015 Chevy Silverado Duramax LML my CP4 went out Being your visual you stated you were going to replace rails and lines I was wondering aren’t you able to just flush out the lines and the rails what’s the reason we need to replace those parts

  • @rcjunkies816
    @rcjunkies816 2 роки тому

    Was the reason to replace the rails and lines Couldn’t they just be flushed out

    also i did the same job with new 3" down pipe and up pipe upgrade and a cp3 conversion and added a lift pump. the cp4 will fail and there is no fix for its failure. you can add a lift pump and extend its life span but tha'ts about it.

    How did you get the fuel rail crossover line out from under the turbo?

    How many total hours labor did you have in it including programing and oil change? Minus video time.
