Various Issues with my New Truck
#21
If you pulled the distributor/pump drive gear it's possible you didn't put it back in correctly and this could be setting the code. In the LA motors you could run it in any position as long as the firing order was correct. In the magnums you can't do it. Get the motor to TDC #1 cylinder on the COMPRESSION STROKE. Remove the cap and see where the rotor is pointing. If you can't set it like in the pic it's probably off.

So I ended up getting a new harness from a reputable scrap yard in very nice condition. Part numbers match up. It runs much better now, but P0340 comes on still. Is there a chance it’s the distributor itself being old and eroded on the contacts? Or am I now to just the sensor and the PCM?

If you are seeing the same problem with a different harness..... yeah, the problem is likely elsewhere. If you have an aftermarket sensor in the distributor, get a genuine mopar piece, see if that changes anything. (don't forget to clear codes after you change it.) The sensor is just a hall-affect switch.... so, no contacts to corrode.

Excited Update: I went to a u-pull-it yard and grabbed 4 of the same sensor with the exact same part number. I walked away with it for under $5! Sweet! I took the nicest looking one and switched the sensor in the distributor. Now it began to throw P1391, so I put the recently purchased new one in the distributor. Still 1391, I grabbed a Crank Position sensor from dodge, and now it runs like a dream! No more codes, now to test drive it and test out the transmission!
