I've got a 2003 2500, 5.9L cummins, late 2003 model year. I had the truck stored for the winter. I jump started it and it ran fine until I disconnected the jumper cables. The engine died. It would turn over, but it seemed like the PCM had failed. I had it towed to a dealer, they've had it for weeks. They couldn't get a pcm from dodge, so I ordered one for them (aftermarket). When it arrived, they installed it and it died after a minute of running. PCM has lost communication. Any ideas on the cause or solution. The dealer seems stymied. I'm not giving up on this truck. I'm assuming at this point, that I fried something besides the PCM. Aside from a voltage or grounding problem, I can't imagine what would be wrong.
