We have a 1992 Plymouth Acclaim. The car just will not start or turn over. I checked all the fuses, the battery is still good, and when you turn the key to the on position it does nothing. Everything else works. Radio, wipers, turn signals, stop lights, flashers, and all. Do you think it is the starter? My son just put in a amp for his stereo. Will that have to do anything with the car not starting? The car is a 1992 Plymouth Acclaim with a 3.0L engine, 70,000 miles.
