Fuel Delivery

Power to the fuel pump relay is supplied from the ignition switch when in the "ON" or "START" position, at which time the ECU supplies a ground for the fuel pump relay. When the relay contacts are closed, power is applied to the fuel pump.

Fuel is drawn through one end of a roller-type electric fuel pump, compressed and forced out the opposite end. Pump capacity is greater than the maximum engine consumption so that the pressure in the fuel system is always maintained.
