I have a 1990 Jeep wrangler. I just replaced the starter because it would crank several times but wouldn't start. It seems that it would crank so many times that it would drain the battery. At first I thought it was the starter (original) so I replaced it. But it still won't turn over. The battery was replaced about 6 months ago. I have had to jump it or push start it every time now. Is it the battery? Is it possible that the battery could have been defective? The ignition sensor was just replaced 2 months ago. I hit a tree about a month ago and every since then it's been doing this. Please let me know.
