Cranks no start issue

Good morning,

When you crank the engine, does the tachometer move up a little showing engine RPM?

That will tell me if the crank sensor is sending a signal to the ECM to turn on the spark.

If you replace the crank sensor and it starts, the check engine light will be on. There is a relearn procedure that must be done with a scan tool for the light to go out and clear.

IMPORTANT: The CKP System System Variation Learning Procedure will need to be performed whenever the Crankshaft Position (CKP) sensor is removed or replaced. Refer to CKP System Variation Learn Procedure.

REMOVAL PROCEDURE
1. Remove the electrical connector.
2. Remove the sensor hold down bolt.
3. Remove the sensor from the timing cover.

NOTE: When installing or removing a crankshaft position (CKP) sensor make sure the sensor is fully seated and held stationary in the front cover before torquing the hold down bolt into the front cover. A sensor which is not seated may result in erratic operation and lead to the setting of false codes.

4. Inspect the sensor O-ring for wear, cracks or leakage. Replace if necessary. Lube the new O-ring with clean engine oil before installing.

INSTALLATION PROCEDURE

NOTE: Make certain that the Crankshaft Position (CKP) sensor mounting surfaces are clean and free of burrs before installing the CKP sensor.

1. Install the sensor into the timing cover.
2. Install the sensor hold down bolt.

Tighten
Tighten the hold down bolt to 8 Nm (71 lb in).

3. Install the electrical connector.
4. Perform the CKP System Variation Learn Procedure. Refer to CKP System Variation Learn Procedure.

Crankshaft Position System Variation Learn

1. Install the scan tool.
2. Apply the vehicle's parking brake.
3. Block the drive wheels.
4. Close the hood.
5. Place the vehicle's transmission in Park (AT) or Neutral (MT).
6. Idle the engine until the coolant temperature reaches 65 C (150 F).
7. Turn OFF all the accessories.

Important:If the CKP System Variation Learn Procedure cannot be completed successfully, refer to DTC P1336 Crankshaft Position (CKP) System Variation Not Learned for additional diagnostic information. See: A L L Diagnostic Trouble Codes ( DTC ) > P Code Charts

8. Enable the Crankshaft Position System Variation Learn Procedure with the scan tool.

Important:After the ignition switch is turned to the CRANK position, the VCM must see a change in the state of brake switch (Released to Applied) to run the learn procedure. Also, the service brakes and the parking brake must be held throughout the duration of the learn procedure.

9. Apply and hold the service brakes.

Important:While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine will respond to throttle position after the learn procedure is complete.

10. Slowly raise the engine speed to 4,000 RPM.
11. Immediately release the throttle when the engine speed decreases.
12. Turn OFF the ignition for 15 seconds after the learn procedure is completed successfully.
