My 98 Mustang GT won't Start!!

Dead battery. Various possible causes:

1) something left on. 2) alternator not functioning correctly. 3) battery defective. 4) something staying on that shouldn't. 5) high resistance in battery cables.

Other than that, a bad starter that just doesn't turn.

6) Did you check to be sure that the cables are properly cleaned and tightened and that the posts on the battery were cleaned before it was installed.

Also make sure the battery's Positive cable is clean at the starter end. Corrosion can build up there and cause nothing but a "click" when you turn the key. I always put silicone gel or vasoline on all of the battery cable connections after cleaning them bright and shiney, it keeps 'em that way.

Thanks everyone for all your suggestions. It was the cables on the battery......... It was loose..... I'm just glad it was nothing major because right now would of not been a good time for that! Thanks for all your help.
