Fuel Injectors



Fuel Injectors





The engine has 8 fuel injectors (one per cylinder), each injector is directly driven by the ECM (engine control module). The injectors are fed by a common fuel rail as part of a returnless fuel system. The fuel rail pressure is regulated to 4.5 bar by a fuel pressure regulator which is integral to the fuel pump module, within the fuel tank. The injectors can be checked by resistance checks. There is a fuel pressure test Schrader valve attached to the fuel rail on the front LH side for fuel pressure testing purposes. The ECM (engine control module) monitors the output power stages of the injector drivers for electrical faults.

The injectors have a resistance of 13.8 Ohms ± 0.7 Ohms @ 20 Degrees Celsius.
