Engine Cranks But Does Not Run

CIRCUIT DESCRIPTION
To start the engine, the correct air/fuel mixture must be compressed within the cylinder, and sparked at the proper time. This assumes that the vehicle battery condition and cranking speed is within specifications, and that an adequate amount of quality fuel is in the tank. The PCM controls fuel delivery, fuel metering, and spark timing. When the key is first turned ON, the PCM energizes the fuel pump to prime the fuel rail assembly. The PCM uses input from various information sensors to determine the correct amount of fuel to mix with the intake air, and the spark timing of the mixture over a wide range of starting conditions.

DIAGNOSTIC AIDS
To prevent mis-diagnosis, perform the Powertrain On Board Diagnostic (OBD) System Check before performing this table. Initial Inspection and Diagnostic Overview

Unless the engine enters Clear Flood at the first indication of a flooding condition, a no start may result. Be sure to check the spark plugs for signs of fouling.

Check for leaks in the air duct between the Mass Air Flow (MAF) sensor and the throttle body.

If the steps above check OK, refer to Hard Start in Symptoms. Hard Start

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table.
2. This step determines if the ignition feed circuit to the CKP and the CMP is shorted to a ground. If all three DTCs are set, this indicates the circuit is shorted to a ground or a sensor is internally shorted.
4. If the fuel pump is not audible at the fuel tank area, listen underhood at the fuel rail. Fuel flowing through the pressure regulator produces an audible hiss.
6. This step determines if the ignition control modules are powered up. If the test lamp does not illuminate. this indicates the voltage supply circuit is open before it splits to both banks of the engine or the circuit is grounded and the ignition control module fuse is open.
