DABLACK,
I don't know where you're located, but if you have something similar to Advance Autoparts in your area, you can pick up one of these babies:

I got mine when I was having fuel issues and then picked up a t-connector at home depot. Its an easy to use setup because all you need to do is take off the feed line, attach the one end of the T to the feed hose, another to the gauge, and the third to a short piece of fuel tubing leading to the injector rail. After that you can monitor fuel pressure at any time.
Could you describe the issue in a little more detail please? Does this occur after the car sits for a certain amount of time? Does the behavior change with engine temperature? Ambient temperature? I experienced hard starts in my car for a while and eventually replaced the fuel pump, installed a check valve, replaced all injectors and also the FPR. Now the issue is nonexistent. My car would be hard to start after it sat for a long time or was parked facing up an incline. The condition was independent of engine or ambient temperatures.
