Most often someone rigs these when the ecu no longer supplies the open-collector ground needed to energize one of these two (main and fuel pump) relays. Usually it is the fuel relay that doesn't get the ground that is supposed to be there when the ecu sees ignition pulses at the coil's low side (ECU pin 1). You may have to replace the ecu (-503 or -510) to make this work properly again.
