Typical example of a fuel Injector
The fuel injector will need to be removed and the
injector will need to be checked for performance.
Do not clean the fuel injectors, as cleaning with
incorrect tools can damage the nozzle. The fuel
injectors should be renewed only if a fault with the
fuel injectors occurs. Some of the problems that may
indicate that new fuel injectors are needed are listed
below:
• The engine will not start or the engine is difficult to
start.
• Not enough power
• The engine misfires or the engine runs erratically.
• High fuel consumption
• Black exhaust smoke
• The engine knocks or there is vibration in the
engine.
• Excessive engine temperature
