Electric Fuel Pump

Fuel under pressure from electric fuel pump flows through a fuel damper (some models) and fuel filter to the fuel pressure regulator. Power for operation during cranking mode is provided from starter relay via the fuel pump relay and ECU.

The first movement of the air flow meter measuring flap (about 5°) closes the fuel pump contacts and provides power to fuel pump after engine has started.

With engine stopped, no air flow is present, measuring flap closes and fuel pump contacts are opened to cut power to fuel pump. This method reduces the risk of fire, in case of a collision.
