Engine Cranks But Does Not Run

Schematic:

CIRCUIT DESCRIPTION
This engine is equipped with a distributorless ignition system called the Electronic Ignition (EI) system. The primary circuit of the EI system consists of 2 separate ignition coils, an electronic Ignition Control Module (ICM) and a Crankshaft Position (CKP) sensor as well as the related connecting wires and the Ignition Control (IC) portion of the PCM. Each secondary circuit consists of the secondary winding of the coil, spark plug wires, and the spark plugs.

IMPORTANT: The Camshaft Position (CMP) sensor is only used for a misfire detection and is not part of the ignition system.

DIAGNOSTIC AIDS
Test/Inspect for the following conditions:
^ A TP sensor that reads too high or skewed may cause an incorrect fueling condition.
^ A TP sensor binding or sticking in wide open position.
^ A TP sensor shorted or open.
^ Fuel contamination
^ Out of fuel
^ Low compression. Refer to Engine Compression Test in Engine. Engine
^ PCM grounds. The PCM grounds will only cause a problem if all the grounds are not making a good connection. If a PCM ground problem is suspected, the most probable place to inspect is where the grounds meet at the engine block.
^ A cold engine that has not been started should display ECT and IAT temperatures that are relatively close to each other.
^ A skewed MAP sensor. The MAP sensor value should change when cranking the engine. Compare any questionable barometer readings with that of a known good vehicle.

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table:
3. While cranking the engine, the CKP activity (CKP reference signal) should increment to 255, then rollover to 0.
10. The CKP sensor should output a voltage near 1100-1300 mV as the crankshaft turns. It is possible to trigger the ICM with a voltage as low as 200 mV. If no voltage is produced, a poor CKP sensor connection or malfunctioning CKP sensor is indicated.
11. A test lamp connected to B+ simulates a reference signal to the PCM.
23. The replacement PCM must be programmed and the Crankshaft Position System Variation Learn procedure must be performed.
