1996 cadilac deville...removed anti thief device and now can"t start car......Northstar v-8 front wheel drive
 
When you disabled the anti theft controls, the car thought you stole it, so it won't start, at least now you know it works, the computer can't detect the control, reconnect it and see if it will start.
 
Can't be done. It's programmed into the PCM. Repair it to proper factory specs, then go to the dealer to have the PCM and the BCM reflashed.
