Fuel Injector Resistor: Testing

1. Disconnect the fuel injector resistor connector. See Fig 1 .
2. Check for resistance between each of the fuel injector resistor terminal Nos. 2, 3, 4, 6, 7, 8 and the power terminal, No. 5.
3. Resistance should be 5-7 ohms.
4. Replace the fuel injector resistor with a new one if any of the resistances are outside of the specification.
