SYSTEM 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.
2. If no sound was heard, check the fuel pump relay and fuel pump resistor and relay (speed).
3. If the fuel pump relay and fuel pump resistor and relay (speed) are normal, check voltage at following terminals.
- ECM terminal 1H (Ignition switch START signal)
- ECM terminal 1AF (Fuel pump relay)
- ECM terminal 1AJ (Fuel pump resistor and relay (speed))
