Hello All! I have found good advice before on this forum, and I return with a real stumper. I have a 94 Ram 5.9 that simply will not stay running. Over a month ago, I put a fuel pump in it. It ran fine after I found it had a bad fuel pump ground wire and that was replaced. Now the truck starts and idles fine, reaches operating temp, will run for about 10 mins then idles really rough, backfires alot, misses/lopes and eventually dies. Truck has a new dist cap/rotor, wires/plugs (less than 600 miles), new coil, new crank sensor (long story), O2 sensor. Had a Mopar friend come with a scanner to help...all the sensors seem fine, timing is good, no codes, dist doesnt have excessive play, etc etc. Still having the same prob. Unplugged the PCM to check for corrosion (& potentially faulty pcm), plugged back it and symptoms continued immediately. He is baffled, but says the only things possible could be a PCM or a wiring issue. Any advice or suggestions would be super helpful and greatly appreciated. I do apologize for the long post (just wanted to cover all the bases).
