If it has the 4.3L or the 2.5L engines it would be located under the hood, on the firewall, drivers side, close to the master cylinder. If it has the 2.8L engine it is located under the hood, on the drivers side inner fender.

Where is the fuel pump relay on 1991 gmc g2500?

If you have a fuel pump relay in the 91 GMC, it will be in the large black fuse box under the hood, on the driver's side, next to, or close by the battery. But I don't think you have one. If I recall, the 2500 has the pump in the tank, and its control (pressure) is on the injector rail. (more like a regulator and it's non electrical) If your pump quit, it's most likely the pump, not a relay.
