Will not turn over! Starter won't engage!!
When you turn the key to on, do the dash and warning lights come on? This would verify power to the ignition switch.
It's like this: you have a positive battery cable with a lot of juice connected to the starter, but not to the starter motor. It is only connected to the starter motor when the start wire out of the ignition switch energizes the starter solenoid, mounted on top of the starter.
So you check the small wire to the starter for power with the key held in start. If it has power then, the starter or the solenoid is probably bad- as long as the battery is charged and the battery connections and starter connection is good.
If you have no power on the small wire in start, trace the start wire back to the ignition switch. You may need a wiring diagram- there is often a start relay, a park/neutral safety switch with automatics or a clutch safety switch with a manual transm., and sometimes a "crank" fuse. All or some may be in the path of the start wire from ignition switch to the starter solenoid. You would need a voltmeter or test light to check this circuit. If you want more help, post back with make, model, year, and engine, and I could look at a wiring diagram for your start circuit, or I could post a link for you to see the diagram.
