I recently went on a trip back home so my car sat for a little over two weeks. I come back and hop in to drive the old girl and she does not start. All the lights, ac, radio everything turns on but she doesn't wanna turn over. I try to start it about five more times and she eventually starts. No problems once it starts, runs perfectly fine. Starts right back up if I shut it off right after driving. Once she sits for a couple of hours I have the same problem. This has been going on for four days now. And yesterday I had a CEL come on. Any ideas on what this could be? Bad battery, starter, bad connection somewhere, etc?
