5.0 DOA (ford techs) ENTER Reply #30 – May 25, 2009, 12:58:41 AM 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. Quote Selected
