The car won't TURN OVER unless you disconnect the coil wire at the cap and let the spark jump to the terminal?? Forgive me, but that makes no sense! Lol.... Ok, so you've got around 35-ish psi at the Schrader valve AFTER the priming, and about 38-40 psi DURING priming?

Now I'm not too familiar with Ford lingo..sorry....is the ECT the computer? (I'm used to hearing ECM.)

So the question is why won't the car stay running....the check engine light should have an answer if it's a sensor problem... I'll wait til you post those codes before I make any crazy guesses. But until then...maybe your EGR or IAC valves are completely frozen up. There, there's my 'shot in the dark' for ya.
