Are you sure it was no power and not no ground pulse?

Does the check engine light come on for bulb check when the key is turned on?

This probably isn't going to be easy to find. It could be a failure of the computer itself but all other external possibilities have to be eliminated first, including these alarm systems. Is this an aftermarket alarm system or factory?
