Thread: Car not starting.

I turn the key and nothing, the little cabin temp sensor fan stops. Dash lights are on. Cranking battery is at 12.36V. The 12.56V was between an earth terminal near the battery and the positive terminal. When I turn the key, I can hear a relay click.
The starter motor was rebuilt about 3 years ago, The contacts replaced. The car was running fine, we went up the HC over the long weekend.
Any Ideas?

Tap the starter with a metal hammer.
Good luck
