I installed audio security for too long is why I ask. Did you remove all the wiring that was under the dash associated with the alarm or just disconnect the alarm module? Was there a relay up in the ignition harness? I am asking all this because depending on what alarm was in there and what you did to remove/bypass/disconnect it may or may not be why the starter is still seeing no power. Most alarms use a negative triggered relay that normally is mounted around the ignition harness to turn off the starter wire when the alarm is active. There are other brands like code alarm that uses a normally open starter kill meaning the starter wire/circuit is open/dead until the alarm connects it when you start the car. So in an alarm like this if you just disconnected the module, you have left the starter circuit open until you find the wires they cut, and reconnect them.
