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.
