5.0 DOA (ford techs) ENTER

It sounds like a computer grounding issue to me. I once wired my ignition box incorrectly and it did the same thing. I also have left the ground wiring near the starter solenoid ungrounded and it did this also. Please check all the grounds for the FI system cause it sounds exactly like a ground problem. Just like when corrosion builds up between the battery terminals, the grounds will do the same if the humidity is high enough. Happened to me a few times for my Nitrous System when living on the gulf coast.

computer pin 60 im guessing out of the original computer was stuck in the ecm connector pushing pin 60 out of the harness. Pin 60 is the ground

I believe pin 40 is also ground, but they possibly connect to different points on the PCB...
