Why won't a 93 Mercury Sable with a new battery start if the lights and everything else comes on?

Answer 1

I fixed a 93 Mercury Tracer same problem. It was the Ignition switch in the steering column. A thicker black wire with a red stripe is the key this wire goes many places but most important it goes to your starter solenoid. The easiest location to pick up this black wire with the red strip is at the cooling fan relay. you can turn the key to the on position and put 12 volts to the black wire with the red stripe and the car will start or at least turn over. I drove mine starting it this way till I could pick up Iginition switch. JMCNEAL2@Yahoo.COM
