My truck did the same thing last month. It's the crankshaft position sensor. In order to fix it your going to have to remove the transmission. . . Hopefully your engine is ok....might need a new one too.
Yea good luck on getting Mopar to do anything for you. They won't do anything for me.I just had the dealership put a new engine in anyways. It's going to run like $15k.
I recently had a new engine put into my 2015 ram ecodiesel. Should I be concerned about the rest of the exhaust? Muffler and resonator? Thinking about removing it after the def system stuff...
