Fuel Injector: Testing and Inspection
Injector Locations
To test the Injectors, located between the fuel rail and the head, proceed as follows.
Injector Audio Operational Test
Using a stethoscope, check the operational sound (tick) made by the injectors (one at a time) during idle or cranking. Check that the sound is produced at
shorter intervals as the engine speed increases.
CAUTION: Other injectors may produce sound as they operate even if the injector under checking does not operate. Ensure that the sound from an
adjacent injector is not being transmitted along the delivery pipe to an inoperative injector.
