It has a brand new fuel pump and filter. It has oil pressure but it wont fire up on its own. If you spray started right in the carb it will fire but only for a couple seconds.
ANY IDEAS???

    Time to let a mechanic take a look with a 'quality' scanner! Several possibilities, too many for guessing.

    Tps stuck high and triggering clear flood, fuel spider,, dist signal,, ecm,, wiring problem are just a few. That is IF the pump is working now!!

    If it quit running and you changed the fuel pump hoping that was the problem. Doesn't sound as if the fuel pump was the problem.

    Have you herd the news about Romo's back injury? Shame, was looking foward to the game sunday night. Maybe Orton can take over and win it but i doubt it. Eagles pretty tough now.
