how does concrete kill the charge in the battery? I personally think that it doesnt matter if you sit the thing on the ground/concrete/block of wood...whatever. If your battery goes dead from the point of taking it out, to the point of contact with the ground and only being there for a little while, you obviously would have needed a new battery anyway. Either that, or you need a new alternator.

The obvious thing is, is that it wont start with the starter. Get out a deadblow hammer, and hit the starter a couple times, if it starts because of that, then you need a new starter. if not, check the wiring.
