When this problem happens (------), this usually indicates a bad instrument cluster. The theft system needs to communicate with the instrument cluster for the vehicle to start and if the instrument cluster is bad, the vehicle will not start.
If the instrument cluster is shorting out, it can pull all of the other modules down with it. When this happens, you most likely will not be able to communicate with them.
You could try to disconnect the instrument cluster and see if you can communicate with the other modules.
