Car not starting up
I have a 2008 Jeep Grand Cherokee Laredo. I was driving around just fine then one day I went to start it and the starter would not crank at all, so I immediately thought it was I bad battery. So I got it jumped and it started up just fine. Later that day I went to get a new battery, I made sure it was hooked up properly and it kept doing the same thing whenever I turn the key all the lights come one but the starter doesn't crank. Is it my alternator? What is going on?
