1999 Buick Regal 3.8 (K) No start condition?

Question

Ok here's the deal.  I have a 1999 buick regal with a 3.8 liter non supercharged engine. Here are my symptoms and what I've done so far:

-Engine turns and intermittently wants to fire but doesnt.  But mostly just turns over
-I have good spark on all 6
-I have good injector pulse
-I show a fuel pressure of about 50 psi
I have replaced coil packs and module, crankshaft position sensor, wires.  I also replaced the fuel filter which was plugged almost solid.

In the beginning it died while driving.  It started misfiring badly and wouldnt restart.  Now I'm here trying to figure out my problem.  I'm almost thinking fuel pump, but I cant seem to find the proper psi online.  And I dont want to make a 300 dollar guess.  

Also, the only codes I was showing was po300, multiple cylinder misfires....as if I needed a computer to tell me that.  LOL  

Thanks for the help.

try pouring gas right into the carburetor if it runs then I'll Guess the fuel line is also clogged  pull your fuel pump and clean it see if you get gas from tank via the fuel line.then the rest of the way to the carburetor.hook everything back up and drive it.Good luck
