Test Description

WARNING: This page is about a different car, the 2002 Pontiac Firebird and 2002 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

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 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 fuel injector ignition voltage circuit is indicated.

  2. 5

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

  3. 6

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