Fuel Injector: Testing and Inspection
FD2 - Fuel Injector Electrical Signal
CAUTION: Do not connect a test lamp to the injector harness. Damage may result to the Powertrain Control Module (PCM).
^ 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 113-0001A or equivalent, into
the injector lead plug.
-
Start or crank engine.
-
Observe whether the continuity checker blinks, which indicates a completed circuit for the injector being tested.
^ Repeat the check for each injector.
^ Do all injector circuit leads show continuity?
YES -- Go to FD3. See: FD3 - Fuel Injector Resistance
NO -- Check for 12 volts at each injector wire with key "ON". Service wire as required.
