Pinpoint Test B: No Start With Spout Connector Disconnected

1. Check For Codes  Perform QUICK TEST. See TESTS W/CODES - 5.8L EEC-IV article. If diagnostic trouble codes are present, service codes as required. If codes are not present, go to next step.
2. Check Battery  Turn ignition on. Check battery voltage. If battery voltage is less than 12 volts, service battery/charging system as necessary. If battery voltage is more than 12 volts, go to next step.
3. Check For PIP Signal  Turn ignition off. Connect EEC-IV Diagnostic Cable (007-00097) to EEC-IV Breakout Box (T83L-50-EEC-IV), negative battery terminal and ICM. Leave B+ lead of diagnostic cable disconnected. See Figure . Ensure PIP OPEN/NORMAL/SPOUT OPEN switch is in NORMAL position. Apply DI overlay on breakout box. Ensure SPOUT in-line connector is disconnected.

Turn ignition on. Set DVOM to AC voltage scale. Crank engine while measuring voltage between J15 (PIP) and J7 (B-). If AC voltage is 3.0-8.5 volts, replace ICM. If AC voltage is not 3.0-8.5 volts, go to next step.

1. Check PIP Signal From PIP Sensor  Connect diagnostic cable to CMP sensor and sensor connector. Turn switch to PIP OPEN position. Crank engine and measure voltage between J7 (B-) and J34 (PIP). If AC voltage is 3.0-8.5 volts, repair open PIP circuit between ICM and CMP sensor. If AC voltage is not 3.0-8.5 volts, check CMP wiring harness connector. Repair as necessary. If connector is okay, replace CMP sensor.
