FD3 - Check Fuel Injector Resistance



WARNING: Before starting these tests, release the fuel pressure from the fuel system to reduce the risk of injury or fire, as outlined in Service Precautions.

^ Remove the electrical connectors from the injectors. If necessary, remove the fuel injectors to gain access to the injector terminals.

^ Measure the electrical resistance of each injector.

^ Is the resistance of all injectors approximately 12-16 ohms (20°C [68°F])?

YES -- Go to FD4. FD4 - Fuel Injector Cleaning and Leakage Check

NO -- Replace the faulty injectors. Repeat Test Step FD1 and if OK, Go to Test Step FD4. FD4 - Fuel Injector Cleaning and Leakage Check
