first, did you clear the codes after replacing the module??? if the codes return immediately, you still have an electrical issue. if not then you may have an internal issue in the injector pump.

I purchased a code reader and another PMD, cleared the service engine light, and started the truck. It ran just fine for 10 minutes, the check engine light returned and the engine died. I then cleaned every electrical connection involved with the PMD, restarted the truck which died after running for about two minutes. Any suggestions?
