My '89 Supra Turbo won't run, any troubleshooters?

i've never had this problem on a toyota but a honda. the 2 main culprits were the map sensor and the idle air control valve. the map was bad due to the car not meant for boost, therefore popping the sensor. the idle air just went bad. if your running a non-turbo i'd check for vaccum leaks between the afm and the throttle body as well.
