Yeah thats the feeling I was getting also you can try to clean the contacts and see what happens. It would be nice if you could read the pass lock enable code.

The trouble tree I gave you has the checking of the ignition switch its one of the first steps after checking the pass lock enable status.

What I was wondering was if the switch was relaying the signal to the bcm for the pass lock feature I only see to use the scan tool for it im trying to chase wires fun fun to check continuity but I would like to remove the key switch to check the pins on it but not sure on what and how to remove it

On that car the security system will disable the fuel injector pluse not the starter. To check the ignition switch put the key in the start position if you have power out of the big yellow wire out of the ignition switch the switch is working. The problem I saw was the pcm was giving a power signal to the crank relay instead of a ground so power goes to the starter.
