My car died on me after it sit for like a day without being driven. I thought it was the alternator but it wasn't, then I went to buy a new battery but then it still didn't work after another day of sitting. I took a blown bulb in the tank and hoof of the car. But it still did not start. I got an circuit tester and took the every fuse I possible can find in and out the car and nothing. What else can be the problem?

That should have worked.
