Question about 1993 Chevrolet K1500

1 Answer

I changed my fuel pump on my 1993 Chevrolet k1500 & now it won't work? I even changed the tank, pigtail, fuel relay... it does'nt have any power source from the fuse inside the hood 20 amp as I checked with my light tester with the key on but nothing ...poured some gas into the throttle body then it started but dies a short time later....would you have a diagram/picture of the harness from the fuel tank to the underneath the hood? or any suggestions would be well appreciated. Thank You.

Check both sides of the fuse. No power at either side? Go back to the relay as that is where the power comes from. Double check that you are looking at the correct relay.

Where is there a jumper bypass for the fuel pump relay on a 1993 chevrolet K1500 pickup 5.7

There were code keys that you could plug into the diagnostic port to bypass the relay pre 95 that you could get from the dealership for about $1 however have not seen them in years if you go to a dealer parts window and ask them they should be able to print a diagnostic port diagram and tell you which terminals to jump to test the fuel pump circuit

Stalling while under power. Won't start right

This is a fuel system related problem.

I will advice that you replace the fuel pump and see that the rating is the recommended pressure with the former.

I hope this will help you.

Good luck.

Fuel pump not staying on 1993 k1500 350

Some GM products also incorporate the oil sender switch into that circuit for fuel pump, so that in case of an accident, engine shuts off, oil pressure drops, in turn, shuts off power to fuel pump. May be worth a look at what your getting for oil pressure, as well as checking switch/sender.
