Did you check your starter?
Try changing the starter.
Multiple "clicks" check for a weak battery Check fr loose or corroded battery cables Single "click" Maybe a bad starter solenoid
Possibly the battery has run down. Process of elimination, check to make certain battery cables make good contact with the battery, charge the battery, have it tested, or receive a boost. Next if unsuccessful check the starter, and alternator.
(1)The battery may need charging, or (2) the battery cable(s) may be loose or need cleaning, or (3) the starter relay may need to be replaced.
Bad battery, starting motor or both.
Dead battery or a bad connection to the battery.
two very good possibilities are the battery, and the starter. its easy to test, just try to jump start it. if it still just clicks it needs a starter. if it starts its probably the battery.
Low battery voltage will cause clicks, and it is also possible that the starter solenoid is too worn in which case replacing the whole starter is best.
Clicking can mean a loose connection between battery and starter. Follow wire to starter and clean/tighten connector at starter.
If the battery is bad, you may only hear clicks. It could be the starter, but I would check the charge on the battery first.
AnswerDim lights and lots of clicks is an indication of too low a charge on the battery. When jump-starting, allow the battery to be attached to the jumper cables for about 5 minutes before trying to crank the engine. If that fails, check for loose battery cables at the battery, ground, or starter. If all connections are good, then the battery is too far gone and must be replaced. Note: You need to find out why the battery discharged - did you leave the lights on? is the alternator bad?.
Battery dead
