Fuel Pump Relay: Description and Operation
System Configuration Diagram:
FUEL PUMP RELAY CONTROL
The fuel pump relay control is basically the same as that for the 1.8L engine installed in the MIRAGE. However, fuel pump relay 1 has been added in order to supply power directly from the battery to the fuel pump motor.
- When the ignition switch is turned "ON" position, fuel pump relay 1 turns ON, allowing the positive battery voltage to be applied to fuel pump relay 2.
- No changes have been made to the control that is effected by the engine control module (ECM)
