Sorry, the truck is a '96, Vortec 350.

I am really thinking it has to be the fuel pump. I pinched off the return line going back into the tank to rule out the pressure regulator. I wanted to see if my pressure jumped with ignition on. No change, still only 15 PSI. This should have ruled out a stuck open regulator. I also pulled the pressure gauge off and put it back on my car just to make sure it is working properly and it was.

Think I might go buy a Delco pump. Just hate grasping at straws with this situation and spending unnecessary money. Damn fuel pumps!
