ECM failure
The early nineties Mitsubishi made ECMs and TCMs are quality computers with the exception of the failing Rubicon electrolytic capacitors that were used to equip these electronic control units.
Engine computer or transmission computer, these will break down after five years or so, some last a few years longer but they are basicaly on bowored time. With the ECU sometimes the failure is gradual, the vehicle may be running poorly, difficult to start, the check engine light stays on, etc... then progressing to the point of not running at all. Sometimes it is sudden death, no start for no apparent reason, when everything seemed fine.

Ocasionally the ISC motor, Idle Speed Control Motor or Idle Air Servo will fail and then short the ECU and burn it, so severely sometimes that the ECU is ruined and can not be rebuilt. If this happens to you, you'll likely know it from the smoke thats comming from your ECU.
