Check the relay, then check the wire harness. and last check the fuel pump it self and that's in the fuel tank. but first check the fuse before you really get you haveds durty.
Good Luck

Where is the fuel pump relay on a 1991 gmc jimmy


Thye fuelpump relay is located to the right of the brake booster. this is for a 1991 gmc jimmy (s-15)

I have enclosed a diagram to help locate the relay.

The most common reason for no fuel pressure on these trucks is not the relay but rather the fuelpump itself. the pump is located inside the fuel tank.

There is also a problem with the wiring to the fuel pump, you will need to locate the top of the tank and then off to side of tank is wiring .
This wiring comes off the top of the tank, you will need to check and there is connector problems..
there is one or two ground wires that come off wiring to top of tank which run to frame, check to make sure the grounds are good. if you end up with a bad pump you will see a notice to rewire a new fuelpump connector. hope this is helpful. good day.3_4_2012_1_29_16_am.gif

1991 gmc jimmy over fueling at start up, it wont start unless you push the gas pedal then it runs rough if you let off it stalls. It is getting way to much fuel...


Sounds like the relay is not shutting off fuel pump. Turn the key to on position ( not start ), pump should only run for a few secounds and you will hear a click and pump should shut off, if it keeps running relay is bad. If it works like it should than fuel regulator (if there is one) would be the next posability.

Fuel pump not pumping


You can Hear fuel running? Where in the tank? If so then it sounds like the fuel pump dettached from the supply line inside the tank.

FUEL PUMP DRAINING FUEL BACK INTO TANK WHEN ENGINE IS SHUT OFF


The fuel is in a continous loop being available at  all times to the TBFI. It has the return path so it can always return to the tank via the return line. Np check valve as the pump runs all the time.

1994 jimmy fuel shutown @spider?


Hi

A very common failure on these is the CPFI unit , or SPIDER as people like to call it.

There is one single injector which feeds each cylinder via a pipe and poppet. The injector becomes blocked and the engine won't start or run.

Before you go condemning this though, just make sure you have good fuel pressure because the fuel pressure regulator or fuel pump could also have a hand in the problem. Make sure the pump is running, and if not then check the fuse, the relay, and the pump itself.

Very best regards
