Fuel Injector: Testing and Inspection
Component Inspection
Check Operation
1. Warm up the engine and let it idle.
2. Listen for the sound of each injector running by using a sound scope or a screwdriver.
WARNING: FUEL IS EXPLOSIVE. WHEN WORKING ON FUEL SYSTEM PARTS, MAKE SURE TO SUPPLY ADEQUATE
VENTILATION TO THE WORK AREA. DO NOT SMOKE, AND KEEP SPARKS AND OPEN FLAMES AWAY.
CAUTION: Make sure the fuel injectors are firmly seated on the fuel rail to prevent movement and possible damage.
3. If no sound is heard, measure injector resistance.
4. If the injector is OK, check wiring to the injector and the voltages of the ECM terminals 16, 17, 34 and 35.
5. If removal of the injector system is needed, refer to "On-Vehicle Service" for the steps.
Fuel Leakage Test
1. Take out the injectors together with the fuel rail.
2. Secure the injectors to the fuel rail with wire.
3. Connect the data link connector terminals FUEL PUMP and B+ with a jumper wire.
4. Turn the ignition switch on.
5. Till the injectors about 60 degrees and verify that no fuel leaks from the injector nozzles.
6. If fuel leaks, replace the leaking injector. Refer to "On-Vehicle Service".
