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

On the vortec engines they require 56 pounds of fuel pressure to start a few pounds shy of that you have a dead vortec you will need a fuel pressure guage to verify

1995 gmc jimmy 4wd 4.3 vortec when hot dies and won"t start, replaced plugs wires cap rotor, oil pressure switch, camshaft and crankshaft sensors, ignition control module. still getting spark and over...


The problem is either your fuel pump relay is overheating our your fuel pump is over heating. They also have the problem with the wire connector on top of the fuel pump melts. This is a known problem with them, when you but a new fuel pump they give you a new connector and a service bullentin regarding this problem.

93 Jimmy with 4.3 vortec, Won't start, no spark. Changed cap, rotor, coil and ignition module. What would be the problem.


Have you checked your fuel pressure? Can you hear your fuel pump buzzing. Remove your gas cap and have a helper turn the key to the run position while you have your ear close to the open tank. If you don't hear anything you have a fuel related issue. Even if you hear the pump buzzing you need to check the fuel pressure as it may not be making enough pressure. If no buzz you may have a bad fuel pump, pump relay, or wiring problem to the pump. That is where I would start.

In a 92 GMC Jimmy, Where is the Fuel Pressure regulator?


If this is the 4.3 liter the fuel pressure regulator is located in the intake valley. You will need to remove the upper half of the intake manifold, once removed you will see a small round regulator located at on end of the injector line.
