Have you checked the regulator? Is there any fuel getting into the vacuum hose to it? Finally, allow the fuel pressure to build, take a pair of vice grips and pinch of the rubber hose to the fuel rail and shut the key. See if the pressure drops. If it does, the problem is most likely the it's the fuel pump. If it loses fuel pressure, it's the regulator.
Let me know what you find.
