    Resurrecting this thread. Mine is doing the same thing. Cranks for along time, starts slow and rough, lots of codes, smell of gas, throttle pedal dead, any help would be much appreciated. Truck is a 2018 Ram 2500 6.4, replacement PCM I think came out of a 2016. HP tuners unlocked the PCM using the stock file I sent them out of my 2018. Almost seems like the MDS cylinders are not firing as well (MDS is deleted, still does this even if I disable MDS in the tune)
