A bad/leaking FPR would cause a lack of fuel I would imagine.

what about the possibility of it just not opening quite enough and causing a blockage?

The chances of that seem pretty slim, but if you can get a spare there is no harm in trying it.

I pulled the vacuum line off of my fuel pressure regulator and tiny spits of fuel came out and a co-worker of mine said that's a sure indication that it is junk.

Fuel coming out of the vaccuum port on the FPR indicates a torn diaphram which means the fuel coming out of the vaccuum port is going into your intake manifold. Hence; running too rich.

Problem solved :)

and to probably answer my question in a dumb way.. The torn diaphragm is from drying out for the almost 2 years it sat with no start and no lubrication?

Very possible.

One final thing before I say enough with this thread... I must have a vacuum leak somewhere that is causing my idle to be around 1200-1300rpm. and my question is that, does it matter which vacuum line I have that could be causing this or is it a specific hose?
