Question
Hi, i own a 1990 Mitsubishi mighty max with automatic transmission it has the 2.4 liter engine and its driving me crazy i personally overhaul the entire engine but now, it starts easily when its cold but after 15 or 20 minutes if i kill the engine, there are no power in earth that could start the engine again,i changed the temperature sensor, changed the valve taps, triple checked the timing, i think  everything. even changed the air temperature sensor located in the map sensor and its very uncomfortable to leave the engine running when im not going to be in a place for a little time, please help. and thank you

Answer
Manuel,
If the temp sensors are not the problem, it may be the car's computer itself. You can read this article for further infomation:

If the ECU has been damaged, your engine can act erratic when the ECU takes over the air/fuel management, which is normally when the engine is at operating temperature.
Good luck!
