Fuel Injector: Testing and Inspection
Fuel Injector on-Vehicle Inspection
1. Warm up the engine and run at idle.
2. Listen for the operational sound of each fuel injector with a screwdriver or a soundscope.
If no sound is heard, carry out the fuel leakage test.
NOTE: The best way to judge the performance of a fuel injector is to compare its sound with the sound of other fuel injectors.
