I recently had the same problem w/no start & theft lite on a 97 cav found bad chassis ground.Negative is bolted to battery tray for ground,battery tray rusted out.rb

 

Might be your ignition switch or key lock cylinder. I would start with the ignition switch as it is fairly cheap +/- $45 and not to hard to change. The ignition switch is located on the left side of the steering wheel. There was a recall on the switch for Cavaliers 1995-97.

The following spells out what's involved:

For what its worth.

 

I wouldn't go replacing parts until you know whats wrong. See if you can get a mechanic it to come with a scan tool andcheck if there are any fault codes.

 

I just had the same problem, ran fine last night, went out this morning, turned over great but would not start, no spark from the plugs. I had only a small amount of rust on my neg. bat terminal and some corrosion on the pos. on. I cleaned them and thought just for the hell of it I'll try starting it. Really didn't think it would make a difference since it was turning over very strong. Sure thing, turned over and started, much to my suprise. Went a few places this morning and it keeps starting.
