Fuel Injector Check

Ensure engine mechanical condition is okay. Ensure no vacuum leaks exist and ignition system is operating properly. Start engine and allow to idle. If engine will not start, crank engine for 10 seconds. Using a stethoscope, listen for clicking sound at each injector. If clicking sound is heard, fuel injector is operating. If clicking sound is not heard, go to CIRCUIT TEST HD in appropriate article:

For OHV gasoline vehicles, see TESTS W/CODES - OHV GASOLINE.
For OHV Flex-Fuel vehicles, see TESTS W/CODES - OHV FLEX-FUEL.
For DOHC vehicles, see TESTS W/CODES - DOHC.
