I just went through this...I hav a theft chip as well that probably works similar to yours.... Does you car start up, run for 2 seconds, ae then die? If it does, the problem is likely you are not disarming the chip.

If you key isn't turning in the ignition, then your steering column linkage might be out of adjustment. You may be physically be in park, but you linkage may not be lined up correctly and the ECM thinks it is in Reverse or something... Try to grab ahold of the steering column, and turn it with you hand to see if that is the problem.

So without telling everyone about how the anti-theft works on the chip, i think you can see where you problem might be, and why trying to disarm the chip doesn't work...YOU think you are in PARK, but the ECM thinks you are in REVERSE for instance..

Hope that helps,
