I have a 1990 Ford Tempo 2.3L 4 Cyl. w/ automatic. I just had trouble today with it for the first time. Went out to the car and it started, turned over and everything, but as soon as letting go of the key, it would die. Had a friend look at it and help me get it home. looking around with the coil and distributor, found a plug going into the coil was cracked a little bit, and we guessed a voltage wire wasn't getting a good connection into the coil. So we got it started a few times, but like 2 minutes after getting it going and driving, it would die again. Finally, it wouldn't start again, so we unplugged the throttle sensor. Also, there's a little disc like part a little bit away from the battery that has wires going to it that connect the positive battery terminal and wires from the ignition. As soon as we turned the key now, we had to take a wire off that disengages the starter, and it would idle fine. Now this part baffles me. It would idle just fine, but as soon as we would put it into gear, Drive, Reverse, Anything except for neutral and park, it would die again. Got it goin a couple times with the throttle sensor unplugged and the starter disengaged, but still dies after a minute. Anybody have any idea or any suggestion that i could try and test out?.... the putting it in gear and it dieing just baffles me. Any help would be appreciated. So far had suggestions about maybe the coil or the plugs, of course already going to replace those, but also possibly an ignition switch, any help is very much appreciated.
