Fuel Injector Resistance

Disconnect fuel injector connectors. Using ohmmeter, measure resistance between injector terminals. See Fig 1 . Refer to the CHECKING FUEL INJECTOR RESISTANCE  table. With sensor temperature at 68°F (20°C), resistance should be about 13.8 ohms. Replace injectors as necessary.
