Theft light flashing, car shutting off?
Everytime I try to crank my car, the theft light starts flashing frantically and the car shuts off. Not the battery and we've tried unhooking the battery. Anyone know what the problem is?
i'm stuck at my exboyfriends house so quick responces are really appreciated!

Call a tow truck, yes I am serious. That is a dealer only deal. sorry I can't be of more help.
Powertrain Control Module (PCM)
* The passive anti-theft system utilizes the engine management capabilities of the PCM to enable or disable the engine.
* The J1850 communications network is used to send and receive messages to and from the PCM.
* At each engine start sequence, the PCM allows fuel and spark until the engine is running.
* Within one second after engine start, the PCM must receive an enable signal from the anti-theft system control module or the engine is dis abled.
* If the passive anti-theft system control module recognizes a stored ignition key code and there is no J1850 communications network concern preventing the PCM recognizing the start enable signal from the passive anti-theft system module, the engine will start and run.
Vehicle Disabling
The passive anti-theft system will be activated and will disable the vehicle from starting if any of the following conditions exist:
* damaged encoded key
* unprogrammed key
* non-encoded key (key has no electronics)
* wiring concern
* transceiver concern
* passive anti-theft control module concern
* J 1850 Communications-Network concern
* PCM concern

i was supposed to be there, i just really didn't want to be. it was understandably awkward.
it had to be towed to a local shop. ended up costing $200. they scanned it and something wasn't firing, and it wasn't picking up the signal from the key or something. i still don't understand what exactly they did, but he said it may not even be fixed forever.
its cranking fine now and i haven't had any problems with it since.

yep, $200 is about right for that. In the biz, that is called CYA for Cover Yo' ***. He is saying that so if it does it again in a week, you can't come back and say "You didn't fix it right!" He did, but it could be a part of the system going bad, either the PCM, or transceiver, and he is just letting you know, that may not be the last of it. Glad everything worked out for ya.
