When you turn the key on, does the "Full Engine Power" light come on? On the 1990's, the light is set by the ECM, so if it is not on (and the bulb is good), it usually means the switch is not sending the ECM the go-ahead.

I had to have mine changed out a while back ago (while under warranty). The light would go on briefly, then while driving, would go out. If it goes on sometimes and not others, it's the switch.
