I have a 2000 ford taurus ses. I started my car this morning and it started right up and then when I got to the store and do what I had to do. I went to come back and it wouldn't start. When I turn the key to start it. I'm only hearing one click and that's it. Can somebody help me and tell me what you all think it is. Some people said it might be my starter but I am not sure. I would really appreciate it.
