Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
