I have 2002 s2000 with about 65k on the swapped engine. Its happened twice during this month where the car wont start and I needed a push start for it to turn over. When I turn the key and push the start button, the car just clicks. The lights on the dash are fine, radio works, and top goes up and down still. Also when I start it when its cold, after it starts a grinding sound comes on like when you start the car and accidentily start it again. Im assuming its the starter? Any help would be appreciated.

 

could just be a bad battery...did you try that first?

 

sounds like a starter. check rockauto.com i get parts for my jeep on that site sometimes.

or if you know of a local parts house go get a rebuilt unit.

 

From the description, I'd vote starter. To save a few $$$, I'd check the battery first just in case.
