Welcome to the Forum!

1. Did you do a Crankshaft Sensor Relearn procedure since you replaced the crankshaft sensor?

2. What year, make, model and engine is your vehicle?

2. What was the initial problem you were trying to fix? Were there any OBDII codes?

Well, anytime the crankshaft sensor is disturbed or replaced, what is called a CASE relearn procedure must be followed or the engine will not run right. It requires the use of a professional level bidirectional code reader/live data scanner like a dealership's Tech2.

Now

Do you mean the starter solenoid mounted on top of the starter clicks, or the starter relay in the underhood electrical center clicks?

Does the Security Light come on and stay on when you attempt to start the engine?

Thank you. It's beginning to sound like you need to do a Security Relearn Procedure to get the BCM and the PCM on the "same page". Here is a link to the procedure.


Not having performed the CASE relearn will not keep the engine from starting.

Sounds more like the anti-theft feature has kicked in. Need to first run the Security relearn procedure I cited.
