8 With the engine OFF and the fuel injector electrical connectors disconnected, measure the resistance of each injector (see illustration). Each injector should measure about 13.4 to 14.2 ohms. If not, the injector is probably faulty.

9 The remainder of the system checks should be left to a dealer service department or other suitably-equipped repairer, as there is a chance that the control unit may be damaged if not performed properly.

10 All models are equipped with a sophisticated self-diagnosis system, whereby any faults are stored as codes within the engine management ECM. By connecting suitable hand-held diagnostic equipment to the relevant connector (see illustrations), the stored code can be retrieved, and the fault identified. See your dealer or repair specialist.
