If I depress the pin on the schrader valve on the fuel rail while someone trys to start the car, I get no fuel comeing out, so I'm assuming its a no fuel issue

That's what my GT did when the fuel pump relay acted up. It would click to prime the pump, but had no fuel when cranking over. I swapped the old relay I kept as a spare, and the car fired right up. So I always keep extra fuel pump relays in the glove box. smile

Here's a '98 GTP wiring diagram, hope it helps:

Thanks. I have to go work on my in-laws roof, so I'll get back to the car tonight

I finally got a minute to do some work, and it looks like I will be purchasing a new fuel pump. This is the first time I've seen one that didn't just die outright, the intermittent nature of this really threw me off.

Got the pump in last night and the car ran great. I ran a few errands, and had no problems at all. This morning I got in the car and it wont start. This is really starting to drive me nuts
