If you are hearing just one click and the starter does not turn, then it sounds like the common starter solenoid contacts problem. Do a search for "starter contacts". The starter's solenoid has worn contacts. This has been covered many times on this site. The fix is to remove the starter and replace solenoid contacts, or replace the whole starter with a rebuilt one, or have your original starter rebuilt by an auto electrical rebuild shop in your area.
Here's a link on replacing the contacts yourself, once the starter has been removed from the car:
