2003 Ford Explorer 4.0l clicking and won't start
My son drives my old 2003 Ford Explorer 4.0l. He couldn't get it started. I tried it and it would click when you turned the key once. Now it isn't clicking at all (bad battery?) I'm wondering what could be causing this problem. We tried jumping it and nothing worked. Starter, fuse, battery, something else? I don't want to replace something and have it not be the problem. Any ideas?
