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?

Ok

I am waiting for your reply sir.

Customer: replied 25 days ago.
Don't know if it's security issue or not getting codes now

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.

Customer: replied 25 days ago.
Here are the codes p0030. P0036. P0050. P0053 p0054. P0059. P0622

Excellent!

So no security codes?

Light is on solid but it was on the last time I drove it and it started easy

Customer: replied 25 days ago.

What is the fuel pressure readings at?

Excellent!

Are you able to check the BCM for codes?

Customer: replied 25 days ago.
b1420. B2948. B2961

Thank you for that information.

Based on what you're telling me, this issue is most likely caused by a faulty passlock sensor inside the ignition lock cylinder housing.

Customer: replied 25 days ago.
what's the fix?

Replace the ignition lock cylinder housing and perform the relearn

Customer: replied 25 days ago.
What's the relearn procedure

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?

Customer: replied 25 days ago.
Tried to start it started then quit ,left key on for 20 minutes security wouldn't go out so I abandoned the reset

YES. So to answer your question, thats the relearn procedure.
