Tapsa-
Thanks for the response but perhaps my description was not clear or I didn't understand your response. I have measured the fuel pressure at the Schrader valve and it was fine. I also checked the flow rate which was excellent. These tests should rule out the pump and filters as possible problems.

When I hot wired the fuel pump, it was running any time the ignition was on whether the engine was cranking, the engine was running, or the engine was not running. The fuel pump relay was totally removed from the car and replaced by a jumper wire. It still had the occasional hard starting. This doesn't mean that the relay doesn't possibly have its own problems, but there definitely is a problem elsewhere that is giving the same problem symptoms.

I'd be interesed in any other suggestions?
Thanks again.
Dave
