They are not getting the proper signal from the ECM, and that could be for many different reasons. Try jumpering a gound to the relays to activate them and see if it starts. It might straighten itself out once its running.

ASD relay

thanks for the reply. The relay for the ASD and Fuel pump can be pulled in if you jumper them to be pulled in. Then fuel pressure is good. The fuel pump relay does not pull in for 5 sec after the key is turn to on, the ASD never pulls in. No spark either. Cannot communicate with PCM using a Autoxray7000. Suspect PCM is bad. Your thoughts.
