The reason it wont start when the lights don't come on is because at that point your eec a.k.a. ecu,pcm or computer isn't coming on. the causes could be ignition switch or eec relay if you can locate the relay that is the most likely cause.
Are the lights in the dash coming on, and it just won't crank or are there no lights at all? If the lights are coming on you need an ignition switch.
If the 2000 Cavalier has no lights an will not start, there is an electrical issue. Check the battery, alternator, and the wiring from the battery all the way to the starter to find the problem.

I always start with the basics.......fuses. Then go to bulbs...... Look in your fuse panel and see if you have one marked tail lights......and check it. the brake, headlights and signals work off another circuit.
Check bulbs & fuses first. If still a problem you will need to start looking at possible wiring issues
The battery is dieing down and you should go and get a new battery or get your battery charged
