The numbers below refer to the step numbers in the diagnostic procedures.

  1. 4

    This step tests for voltage at the fuel injector harness connector. The F/P-INJR fuse supplies power to the coil side of the fuel injector harness connector. If the fuse is open, a short to ground on the ignition 1 voltage supply circuit of the fuel injector is indicated.

  2. 5

    This step verifies that the PCM is able to control the fuel injector. If the test light flashes, the PCM and wiring are okay.

  3. 6

    This step tests if a ground is constantly being applied to the fuel injector.
