Trouble Starting my car

I have a 97 Jeep Wrangler and i tried to start it today and all it did was make a rapid clicking noise. All the gagues and the radio turned on fine though. Anyone know what the problem could be? Any help/idea/suggestion would be greatly appreciated!

it may be the starter. im not sure how to check to see if thats it. good luck

Agreed, could be the starter. Also check for corrosion and tightness at the battery/starter terminals. They might be letting enough juice through to operate low-draw items like the radio, but not enough for the starter.

hit the starter with a hammer while someone is turning the key
