sounds like a bad battery to me. although you charged it how do you know it is really good? did you check the specific gravity - only real way - also check amps from battery to the starter.

the 1GM10 is difficult to start in best of circumstances. also - try two batteries and see if she'll turn over.

visit for more info - good site. also google "1GM10 hard start" at least a billion web pages on the topic..>
