Every so often my 93 Dakota decides to "play dead". Checked the obvious: wire harness, battery voltage, sensors, relays, coil. Believe it or not, I'll swap the ECM to a spare I bought from a member here and it will fire right up. Then I'll swap back to the first ECM and it'll be fine until it happens again and the cycle repeats itself which is trending to once a year.
