A friend of mine is having trouble with his Jeep. It won't start, and I tried to take a look at it to determine the problem, but was not too much help to him. We tried jumping the car to see if it was the battery, but that didn't work, so i'm not sure what the problem is. It doesn't try to turn over at all. If someone could come out and look at his Jeep and maybe determine the problem he would greatly apreciate it.
