Fuel Pump Control Inspection

1. Turn the ignition switch to START and check operation of fuel pump relay and fuel pump resistor and relay by listening their operating sound.
- If no sound is heard, inspect the fuel pump relay and fuel pump resistor and relay (speed).
- If the fuel pump relay and fuel pump resistor and relay (speed) are normal, inspect voltage at following terminals.
- PCM terminal 1H (Ignition switch START signal)
- PCM terminal 1AF (Fuel pump relay)
- PCM terminal 1AJ (Fuel pump resistor and relay (speed))
