Engine will not start

I have been communicating with Louie on this issue for a while and have a reply back to his last question which is in quotes. "There's your problem the dark blue wire's shouldn't have power it should be the ground control from the pcm. Here's what I would do unplug all the pcm connector's and see if you still have power to the dark blue wire's to the injector's. If you lose the power then plug the connector's back into the pcm and see if the power come's back. Let me know what you find."

Here is what we found: With key on and PCM plugged in both wires had power.
Disconnect the PCM and power is lost on the control side of the injector. Still have power on the battery side.

We are wondering if there is a ground fault issue or voltage surge causing PCM damage. Could I really have three faulty PCM's?

Thank you,
Larry
