Question 1994 s10 blazer fuel pump replacement

Help. She won't start. Trying to restore a 1994 s10 Blazer, almost complete. Was running, had holes in the gas tank, replaced: tank, sending unit, fuel pump, fuel filter and lines. Runs great on starting fluid, won't even pop on it's own. I can hear the fuel pump run and I bled the air out of the system before the manifold. IDEAS??????

Well, I'd suggest a fuel pressure test, and check to see if your getting fuel to the injectors.

Thanks for the reply. I think your right, when I bled off the air the pressure seemed a bit low. JCW probably shipped me the wrong pump, probably why it came free with the sending unit. Before I drop the tank and put the old one back in, is there an easy way to see if I'm getting fuel to the fuel injectors?
