I am trying to solve my no fuel pressure at the rail. From reading your post I would ask this question. If the dealer said the PCM was not providing power to the ASD relay to turn on the fuel pump, then how would you expect fuel pressure? If the fuel pump will not turn on then it can not create fuel pressure. I would say the dealer is just throwing parts at the problem and the tech does not really know how to diagnose the problem. It is possible that the PCM going bad is coincidental since she ran for a few weeks. I would get a second opinion from a shop that works on Jeeps.
