So I let my car sit for a week, then it started right up this morning. I drove it for about 30 min then let it sit for 3 hrs. Came back to my car it almost didn't want to start but it did. I let it sit and idle for about 10 min then the car turned off. I tried to turn it back on after that but it just kept cranking again and would not start as usual. Does this help to narrow down the problem??
