    Here is a similar case and the diagnostic >>


    No start. Has no spark or injector pulse. No Malfunction Indicator Lamp (MIL) light Key On Engine Off (KOEO) or cranking. Tech removed the Powertrain Control Module (PCM) behind the glove box and the light came on when disturbed and the engine started.
    Tests/Procedures: 1. Check B+ and B- at the PCM. See diagram, when no start happens again.

    2. Wiggle tug test wire harness by the PCM.

    3. Hold the PCM and tap test the case and see if the engine stalls if running or KOEO see if the MIL goes on/off.
