Electric Fuel Pump

Fuel under pressure from electric fuel pump flows through a fuel damper, fuel filter, fuel injectors and fuel pressure regulator. Electrical power to fuel pump is controlled by ECU through fuel pump relay.

When starting, the fuel pump relay becomes activated for 5 seconds by ignition switch being turned to "ON" position. Fuel pump remains on when signal from crank angle sensor indicates that engine is running. If engine should stall, fuel pump relay becomes deactivated after one second.
