No starter action, standard corporate protocol is missing

Changed the intake manifold gaskets, at first it started and ran for a minute but did not sound right so I shut it off. At restart the relay would click but starter did not turn. I replaced the starter, starter relay and ignition switch. Now relay does not click and starter will not turn. I called a locksmith because the theft light on the dash is flashing rapidly. He diagnosed the SCP (standard corporate protocol) is missing there are no blown fuses and no trouble codes what can I do next?
