Also check the over boost sensor switch. You'll find it on the back side of the bypass valve assembly, towards the drivers side. There is a single wire connected to this (the color of the wire is usually white). The overboost sensor wire must be grounded in order for the fuel pumps to run. When the the switch senses too much boost, it cuts the ground, and fuel pumps stop. You could rule out the switch by temporarily grounding the wire directly to the engine...take the car for a drive and see if you still have the problem.

In your car the switch works with a rectangular yellow relay in the engine compartment electrical panel that is famous for causing trouble.
