No Start W/ Spout Connector Disconnected (Remote Mounted ICM)

  1. Ensure SPARK OUTPUT CHECK has been performed. See NO-START DIAGNOSIS in BASIC TESTING article in the ENGINE PERFORMANCE section. Turn ignition on. Ensure battery has 12 volts.
    WARNING: DO NOT connect EEC-IV diagnostic cable and PCM to EEC-IV breakout box simultaneously.
  2. Turn ignition off. Connect DI Diagnostic Cable (007-00097) to EEC-IV Breakout Box (T83L-50-EECIV), negative battery terminal and ICM. See Figure . Leave B+ lead disconnected. Ensure PIP OPEN/NORMAL/SPOUT OPEN switch is in NORMAL position. Apply DI overlay on breakout box.
  3. Disconnect SPOUT connector. Set DVOM on A/C scale. Crank engine while measuring voltage between J7 (B -) and J15 (PIP). If voltage is 3.0-8.5 volts AC, replace ICM. If voltage is not 3.0-8.5 volts AC, connect diagnostic cable to CMP sensor and sensor connector.
  4. Turn switch to PIP OPEN position. Crank engine while measuring voltage between J7 (B -) and J34 (PIP). If voltage is 3.0-8.5 volts AC, repair open in PIP circuit between ICM and CMP sensor. If voltage is not 3.0-8.5 volts AC, check CMP wiring harness connector. If connector is okay, replace CMP sensor.
