Well today, I went out and tested a bunch of things on the car.

First, I tested the fuel pressure a few times at prime. On the first initial prime I had 39 PSI, then I started it and the pressure dropped to 38.

I tried it again, on prime I had 34 and running I had 32.

Then again, the prime was at 36, and running was 34.

I removed the vacuum line from the fuel pressure regulator and I wasn't leaking any fuel.

I also checked other vacuum lines and check my wires and plugs. Everything looked good.

Traced the entire fuel system and that looked good. The only thing I'm worried about is that perhaps the fuel filter is clogged, but that wasn't changed all that long ago.

So I'm left to believe that it's a fuel pump. Going to travel to the GM dealer today and get a genuine one.
