check for proper ground and feed voltage at pump with pump on ..
you also stated spraying carb cleaner to check for vacuum leaks..this is good for cleaning metal only..this product over time destroys gaskets and rubber compounds..

Haha yeah. I am not too used to working on vortec 350's. The older TBI 350's and I am all over it. I guess I should have tested the fuel pressure with the truck running. I didn't even think of that.
Sucks that things always go out when it is cold out and you freeze your fingers off. I just hope it isn't my new fuel pressure regulator again. It would suck to have to rip into there again. Not to mention that little thing was 60 bucks.
