Check that the flywheel is not missing any teeth. Also check the geartip at the starter where it kicks into the flywheel for wear at the tip.

Its likely that you have either a bad ignition switch or a bad neutral safety switch (if stickshift, clutch switch) Try starting in neutral...if it starts, change neutral switch (jump across clutch switch, check starting in neutral with your foot on the brake) Ignition switch is on top of steering column under dash.

first remove the battery and take it to a auto parts place and have them check it. move on from there. if the battery is good the do a starter draw test. take a meter and hook it to your battery. now have someone try and start the car. if the voltage on the battery drops from 12.8 to below 9 volts then the starter is bad. if the voltage doesnt drop much at all then its prolly the solenoid both of which require starter replacement since most solenoids are on starters. if still nothing then check ignition switch. but before anything else ensure vehicle is in park. if it is in part use a meter to test neutral safety switch.

Sounds like a bad starter solenoid, usually cheapest and easiest to replace the starter and solenoid as a unit. It is always best to check for power between the solenoid and the starter with a test light, if the solenoid clicks but the test light doesn't light up you have found the problem in the solenoid.
