So I have a 2002 1500 with the 4.7, 4x4, around 240K miles on it. It belonged to my younger brother before I got it, he wasn't the best to it, I got it mostly to stop my dad from junking it. It's been a good truck up until around three weeks ago.
Three weeks ago it cut off driving down the road like it ran out of gas. Got it towed home, only code has been a P0340.
Replaced cam sensor twice, no dice. Replaced crank sensor, no dice. Tried another PCM, no dice. Wiring harness has been repaired so double checked the repairs, all were good except the harness being made of aluminum was different to me.
Then came the fun, I've swapped the relays around and fuses, still nothing, just cranks and cranks. Cleaned every connection I could find, cleaned the battery cable ends, tried a different battery, felt most of the harness down for bare spots, most of what any normal diagnostic should be.
Only things I've noticed is the OBD reader shows ZERO engine RPMS cranking it over, and it cranks normally, not too fast or anything. I'm about to try an engine harness in it. I've also heard about the ASD in the fusebox? I'm not a big Dodge guy but I really like this truck, it'll go anywhere and pull anything short of a house around.
