Both the PCM and the BCM circuits are fused to hopefully keep anything bad from happening to those computers. unplugging those fuses will only amplify your problem and could put the vehicle in full lock down, if that happens then the dealer is the only place that can redo what been done. However if you haven't already gone too far then try this: From inside the vehicle manually lock all the doors except the drivers door, next exit the vehicle with keys in hand, close and using the key lock the drivers door and watch the dome lights, when they go out wait at least 2 minutes, then using the key unlock the drivers door and see if the vehicle will start and run, if it doesn't then your headed to the dealer to have the system reset and checked for any underlying problems.
