1991 Chevy c1500 short bed 7.4 with a 25 gallon tank.
Suddenly Stopped idling properly, acting like starved for fuel, wanted to die. fuel pump fuse is good.
Swapped the entire fuel pump assembly for a new delphi/ac delco.
Pump does not prime, no start. There is no pump priming process for these, correct?
Anything I might have missed?
If accidentally I swapped the fuel delivery and return lines, how do I distinguish one from the other? any fuel pump damage if I did?
Another possibility is I installed the wiring plug in reverse, but I'm not sure it would go in that way. (I did reinstall the ground.)
Last option will be to swap the fuel pump relay.
Any ideas are appreciated.
