Are you saying that the engine will not start due to a security system issue?
The security light is on solid with the key on?
Have you checked for codes in the computer?
I am waiting for your reply sir.
Ok, sounds good.
If the security light is on solid or if the security light blinks with the key on, it can certainly be the security issue preventing the engine from starting.
Thank you for that information.
So no security codes?
What about the security light?
Ok, does the engine remain running on starting fluid?
What is the fuel pressure readings at?
And your sure all fuses are good?
Are you able to check the BCM for codes?
Based on what you're telling me, this issue is most likely caused by a faulty passlock sensor inside the ignition lock cylinder housing.
Replace the ignition lock cylinder housing and perform the relearn
You posted in your first reply that you have done the reset procedure.
I assume thats the relearn procedure.
What exactly did you do in the relearn?
YES. So to answer your question, thats the relearn procedure.
I am glad I can help!
