Fuel Control Operation

Fuel control system consists of an electric fuel pump, control relay, fuel filter, fuel injectors, fuel pressure regulator, fuel lines and airflow sensor. Fuel is supplied to engine through 2 electronically pulsed (timed) injector valves located in fuel injection mixer above intake manifold (Galant has only 1 injector). The ECU controls amount of fuel metered through injectors based upon engine demand information, through data sensor signals.
