FD3 Check Fuel Injector Electrical Signal

^ Check the electrical continuity of the injector between each injector and the PCM as follows:

- Disconnect the fuel injector lead and insert the continuity checker from Rotunda Fuel Injector Tester/Cleaner Kit, 113-00015 or equivalent into the injector lead plug.

- Start or crank the engine.

- Observe whether the continuity checker blinks (showing a completed circuit for the injector being tested).

^ Repeat the check for each injector.

^ Do all injector circuit leads show continuity?

YES -- GO to FD4. FD4 Check Fuel Injectors (Cleaning and Leakage)

NO -- CHECK for 12 volts at each injector wire.

SERVICE wire as required.
