Here is a good video for helping you test the FPR, sometimes if the diaphragm is ruptured it will take a minute or two to leak, but you should still smell fuel right away if it is going bad.
The part you want to see starts at the 1:50 mark

Shawn did you try cracking the throttle yet while trying to start it?

Well, if you aren't sure if it'* fuel or ignition, the next time it won't start I would run a simple test for spark with a spare spark plug hooked to a wire. If the first wire doesn't spark, confirm with another wire just to be sure, and if no still no spark, then I'd use the following:

Part 1 -GM 3.8L Ignition Module Test and Crank Sensor Test (3X, 18X)

I used it on my non-running '95 Bonnie project and solved it,

No not yet haven't drove it any today. But as soon as I do I will let ya know.

Guys I'm still working on this I had an oil leak that I've been ignoring for to long. Oil pan gasket I replaced it today it was leaking a lot of oil right on that crank sensor I'm gonna clean everything up really good now and see what happens. I did crack the throttle on it this morning when it was not wanting to start and it made no difference. But like you said I'm pretty sure it either crank sensor or icm just got to figure out which one.

Oil could have fouled the sensor readings of the crank sensor, clean it off with some electrical contact cleaner, and let us know if there are any changes.

Hope you RTV'd that gasket due to the ripple in the sealing surface of the pan.....

ok guys I know it'* been a while but I'm back lol. changed out ICM and crank sensor and no change. also tested the fuel pump regulator for about 5 mins and it never leaked any gas out. still does the same thing cranks rite up when it'* cold but after it runs a while and is hot if you turn off to go in a store or whatever it will turn and turn before it wants to crank back up. I have cracked the gas a little pumped it turn on for a min and turn off the. back on before trying to crank and still does the same thing. But once it does crank it runs like a champ. Any one have any suggestions ??

I think you may have misread what I posted about cracking the throttle.

Gently open the throttle a little, then attempt to start. If it fires right up and runs and if you let go of the throttle and it stalls, its IAC related.

Also, do you know what the fuel pressure is KOEO(Key On Engine OFF)?
