Fuel Injector: Testing and Inspection
Fuel Injector Test
1.
Disconnect the injector wire connector from the fuel injector.
2.
Place an ohmmeter on the fuel injector terminals. The resistance reading should be 16 ohms plus or minus 12 ohms at 20°C (68°F).
3.
If there is infinite resistance, or the resistance reading is outside the listed specification, the injector is defective, and must be replaced.
