I have a 1993 lincoln mark viii. It won't start. It was working fine and driving very well, then all of a sudden I come out of the store and get into my car and it won't say a word. The lights and radio comes on and the windows work, but it will not turn over at all. Later that night I went out to see if it will start and it started right up...NO PROBLEM. The very next morning the same problem all over again....won't start. I bought a new battery thinking that was the problem and still the same thing. I was told by the Tow guy that it was my starter. I tried jiggling the battery cables around and that didn't seem to help either. What in the world could this problem be....I'm a single parent and really can't afford a new car.
