The fuel pump relay and fuses are in the fuse box on the driver side inner fender... if the cover for the box is still there, you should be able to tell which is which.

Pull the fuel pump relay and see if the pump still runs in ACC position. That might tell you that at least everything is "normal" from the relay on back to the tank.

The way the pump is spoza work is pretty screwy louie... when you hit the starter, the pump runs, when the engine starts, the main relay pulls in which in turn pulls in the fuel pump relay, and it stays on until the engine stops.
