Remove the Fuel Pump Main Relay from under the dash. It is to the left of the steering wheel, mounted on the back of the fuse panel.
Main Relay
Attach battery positive voltage to the No.4 terminal and battery negative voltage to the No.8 terminal of the Fuel Pump Main Relay. Then check for continuity between the No.5 terminal and the No.7 terminal of the Fuel Pump Main Relay.
If there is continuity, go on to step 3.
If there is no continuity, replace the relay and retest.
Attach battery positive voltage to the No.5 terminal and battery negative voltage to the No.2 terminal of the Fuel Pump Main Relay. Then check that there is continuity between the No.1 terminal and No.3 terminal of the Fuel Pump Main Relay.
If there is continuity, go on to step 4.
If there is no continuity, replace the relay and retest.
Attach battery positive voltage to the No.3 terminal and battery negative voltage to the No.8 terminal of the Fuel Pump Main Relay. Then check that there is continuity between the No.5 and the No.7 terminal of the Fuel Pump Main Relay.
If there is continuity, the relay is GOOD.
If there is no continuity, replace the relay and retest.
The main relay is mounted behind the fuse box under the dash. The unit houses two relays. One relay is used to supply power to the ECU, the injectors and to the second relay. The first relay is energized whenever the ignition switch is turned on. The second relay is energized for two seconds when the ignition is turned on and when the engine is running, to supply power to the fuel pump.
Resistance value continuity [2]

[2] Between No.5 terminal and No.7 terminal when,
Battery positive voltage applied to No.4 terminal
Battery negative voltage applied to No.8 terminal
