I noticed you are a ford certified mechanic. I'm by far, no mechanic but i know my way around a vehicle and have, for the most part always been a ford driver, particularly their trucks. I've done everything i can think of, and can not figure this out. In my mind i keep coming back to the ecm. Is there anything else i am missing? I've put un new coul, new distributor, new ignition switch, new ignition module, new ignition tumbler. I have excellent fuel pressure. When testing i get spark when i first turn the key on then nothing. Any other ideas you may have, I'm eager to listen. My ecm, although i see no bad solder, there is evidence of water leaking into it and in the circuit board itself, there is a significant size yellow/brown spot.
I appreciate anyother input you may have,
Thanks, John
