I was wondering if anyone could tell me what the syptoms are when the fuel pressure regualtor isnt workin right? also how would i check that??

 

Pull the vacuum hose off the FPR while the engine is running. If fuel comes out then it is bad

 

Go buy a fuel pressure tester kit from your local auto parts store. Put it on, tape it to the windshield and drive around a little. Pressure should be around 43 stock, but of course changes depending on load. If you see spikes and stuff it's probably bad (or fuel pump or filter). But I'm no expert, maybe someone else has some better expertise on fuel systems. My .02.
