The computer probably needs to be matched with the anti-theft for it to start. This will require a trip to the dealership.


I will load it on a trailer and take it in. I was,afraid of that.

Yes, anti-theft has it's good points, but it can be a big pain in the butt also.


The new PCM (Computer) must be programmed (flashed) to the car using your vehicle identification number or it won't work. HTH. -Jim
