Do you get power to the fuse box under the hood (next to the battery)? How about the relay box (on the passenger side). There are two inhibitor relays giving power to the the fuel pump and distributor. Do you have power in the car? Do you have power at the starter with the key on?
Open both doors, hood and trunk. Close hood and trunk, passenger door, and then driver door. Use the key to lock the driver door. Wait 1 minute, and use the key to open the door. That should reset the alarm (if any) - factory alarm. I have no aftermarket support.
