2002 Dodge 1500 Van, :"NoBus" Message and doesnt start

This question is answered

The owner had the Computer and an ignition swtch replaced, Both times the same problem returned in a few days. I now have the vehicle and yesterday it wouldnt start, yet this morning it started up no problem, then quit after 30 minutes. I also noticed when the problem is occurring the guages do not power up, yet all lights in instrument cluster do work. Any suggestions would be appreciated.

  • Sounds like you need a wiring diagram, to check your power and the ground connections to your PCM.

    Have you checked the auto shutdown relay? I have experienced similar problems with a faulty relay.
