My 4Runner does not start. Battery is fine. I hear a click, but it doesn't turn over at all. Is that the starter? Or maybe the alternator? Any tricks to get it started before I pay for a tow?

Check the connections on the battery terminals. Sometimes they can be loose. If you just hear a click click sound when you turn the key the battery isn't putting out all the way. I hope this helps you.

Hopefully, reading this will help:

It was the battery... so that was a nice easy fix.
