I think i am having the same problem that is why i am bringing up this old thread, did you ever solve this problem? and can i have a dyno shop turn it off?

 

If you can get a voltmeter into the passlock wiring and get it to fire properly one last time, you can measure the resistance and splice in the proper resistor, bypassing the passlock. That garbage is known for wearing out prematurely and then you need a whole new ignition cylinder assembly which is over $100. I went through this a few years ago. Sometimes banging on top of the column will help you get it to start.

 

Bringing this thread back.. My truck is doing the exact same thing.. btw the vats its turned off in my tune
