Fuel pumps very rarely just die - they usually make an agonising noise, which gets progressively louder over several thousand miles. I doubt it's the pump. The fuel pump relay, OTOH, is a very common failure ;-) Your starting point should be to figure out whether it's fuel or ignition. You should be able to hear the pump start for a short period when you first turn on the ignition. Do you? If you can't figure it out that way, remove the pipe feed to the fuel rail (careful - high pressure fuel) and put it in a jar. Turn the car over, and see if you get fuel in the jar. If you're getting fuel OK, test for spark. > Additional maybe related information: Over the past months, > occasionally the engine would cut out on deceleration kind of acting > like the hooter valve was going.

Even if the dump valve failed catastrophically, the car would still start. It would run badly, but it would start. Let us know what you find. -- Grunff
