bro,
check the ingnition wire harness... where you jump out the turbo timer.. if you checked all of the fuses and the termanal connection. Meger the CPU power wire for conductivity, and the ignition switch.. really it sounds like the computer is gone but not too sure.. you got to check the system.. from the battery in.. if you just put on a alarm then it seems likey to star there.. but i think maybe this is related but in a different area.. where did the installer draw the power from, what kind of security systems is it? remote starter? built in turbo timer? these are serious questions.. if they tapped in at the harness that comes down the steering collum from the key switch then that can be the answere.. i have seen that before.. you said that you smelled burning then i would look there first.. batttery, switch, ECU, if they meger out and you got power.. then i would be looking for the relay.. this is not likely..
