The shop is ripping you off. Your truck has one PCM. (powertrain control module.) Some folks may call it ECM, but, it is one and the same thing.

no pcm is on the fire wall I changed that, ecm is in the block wich I changed too

So it does. That's news......

What brand crank sensor did you get? If it wasn't genuine mopar, may want to get one from the dealership, and see if that doesn't improve its attitude.

The new trucks do have one PCM on the block that controls both engine and transmission functions. The second gens, however, had a PCM on the fire wall and a Cummins ECM on the block. The ECM almost never goes bad. I do agree with you, however, that the shop is ripping him off as they charged him good money and did not fix the primary complaint.

well I went there today and they said it’s a ground wiring issue, however I did chek all wires and checked the amps, there all good, I have no clue what is going on

Find a new shop!!! Where in WA are you?

Spokane wa, and I bet they will charge me up the ass too

Oh, there should be tons of diesel only shops up there. And they may charge you up the ass, but what has the current shop been doing? At least they'll fix it once and not screw you around. Or just take it Cummins by the airport!
