I would start by checking the connections at the battery and the starter. If the connections are ok then try tapping on the starter with a hammer while someone turns the kay to the start position. If the car starts replace the starter. If the car does not start you will need to check the voltage at the starter wires to make sure you have the correct amount there. First check the big wire it should have battery voltage. If it does check the little one with the key in the start position. If you have battery voltage replace the starter. If you don't have battery voltage at the big wire check for corrosion in the wire and connections all the way to the battery. If the small one does not have battery voltage try starting it in neutral you may have a transmission range sensor going bad, or possibly an ignition switch.
