We have traced the problem to the crank angle sensor not getting power. It will crank but not turn over. What could be the possible problem? We have tested the fuses, the coils and many other things they all seem to be getting power but the crank sensor.

We need to make sure the way you are checking for power is by disconnecting the connector and check each terminal for power.

If none of the terminals have power, then the ECM is faulty and not sending power to the sensor to power it.

Please see the info below on the wiring diagram and the connector view that will help with this testing.

Please run through this and let us know what you find. Thanks
