Hello and welcome! My name is ***** ***** I can assist you with your question.
One minute while I pull up your vehicle
Is the computer grounding the starter relay with the key in the CRANK position?
There are 4 female pins that the starter relay plugs into. Two of them should be power and the third one should be grounded with the key in the CRANK position. The starter relay may be missing a power or the ground preventing it from activating
You will need to test this right at the starter relay
While an assistant turns the key to the CRANK position
Here is a wiring diagram of this circuit
So if you insert that relay and turn the key to the CRANK position, does the relay click?
It should or 1) it does not have the correct inputs to it or 2) the relay is bad.
Ok, that is the problem.
Was the passlock or ignition lock cylinder replaced?
I am.. It just takes time to type.
Did you check the BCM for codes?
Or do you only have access to the PCM?
Have you tried to do a relearn procedure?
Here is a youtube video. It is rather long but it does show you everything. This is the same setup you have on your vehicle. You can fast forward through the middle of the video if you would like.
It is possible that the ignition switch itself is bad. Or the pass lock sensor inside the ignition switch. However if this was the case it will usually set a security code in the computer
You would have to check and verify the inputs to the BCM and then replace it if needed.
Maybe we should do this over the phone.
Its a lot of extra work on my part. That is what the extra fee is for.
Lets do this so it is fair for both of us. Can you provide me with an excellent rating now and I will go the extra mile for you (without the extra fee) and will do some digging for you.
