FD3 - Check Fuel Injector Resistance

WARNING: Fuel in the fuel system remains under high pressure even when the engine is not running. To avoid injury or fire, release the fuel pressure from the fuel system before disconnecting any fuel line.

To release fuel pressure, refer to the Fuel Pressure Release procedure. Service and Repair

^ 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 injector(s) and rerun Fuel Pressure Test.
