CIRCUIT DESCRIPTION
This engine is equipped with a ignition system called the Electronic Ignition (EI) system. The primary circuit of the El system consists of the following components:
^ Two separate ignition coils
^ The electronic Ignition Control Module (ICM)
^ The Crankshaft Position (CKP) sensor
^ The related connecting wires and the ignition control portion of the PCM

Each secondary circuit consists of the following components:
^ The secondary winding of the coil
^ The 2 connecting metal strips molded into the coil housing
^ The spark plug boot/connector assemblies
^ The spark plugs

DIAGNOSTIC AIDS
^ A small amount of resistance in the battery positive voltage circuit to the PCM may cause a no-start. Test the B+ circuit for excessive resistance or corrosion. Refer to Wiring Repairs in Diagrams.
^ The PCM grounds will cause a no-start only if all of the grounds are not making a good connection. Refer to Testing for Intermittent and Poor Connections in Diagrams.
^ Inspect the Throttle Position (TP) sensor for the following conditions:
- Any binding or sticking
- An intermittent short
- An intermittent open
- Refer to DTC P0105 Manifold Absolute Pressure (MAP) Sensor Performance/Range. P0105
^ The Engine Coolant Temperature (ECT) sensor may be skewed within specifications and not set a code. On a cold vehicle the ECT and Intake Air Temperature (IAT) should be within 3°C (5°F) of each other. For a hot vehicle, let the engine cool to the ambient temperature before performing the test.
^ The manifold absolute pressure (MAP) sensor may be skewed within specifications and not set a code. Refer to DTC P0105 Manifold Absolute Pressure (MAP) Sensor Performance/Range. P0105
^ A loose crankshaft position (CKP) sensor may cause an intermittent no-start condition by moving away from the reluctor wheel. Verify that the sensor and the mating surface are clean and tight.

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table.
4. Verify that the fuel pump runs by removing the fuel cap and listening, or by feeling the fuel rail or fuel lines on key up.
7. Repair the cause of the malfunctioning Spark plugs before replacing.
8. Inspect for basic engine malfunction like low compression, burnt valves, worn timing chain and gears, etc.
22. A short to voltage in this step will read as a negative resistance.
28. Any time the CKP sensor is removed the Crankshaft Position Variation learn procedure must be performed.
31. The replacement PCM must be reprogrammed and the Crankshaft Position Variation learn procedure must be performed.
