my car wouldnt start a few months ago. it would start every now and then, but i had to try a few times, and sometimes it wouldnt start at all. I had the positive battery terminal and all the connections, replaced, and re-done. This fixed the problem. I dont think you are having the same problem, but you could check your connections to the positive terminal.
