Haha, thanks for havin my back on the battery cables panzer, thats usually the first thing I suggest, but I completely forgot this time!

But yes, check the battery cables for corrosion, remove the boots as well and clean it all, not just what you can see. The boots remove by pushing the screw portion out, and then they slide right off.

The most pain free way I have found to clean corrosion off cables is to find a small container of some sort (I used a topless soda can) and fill it up with a mix of water and baking soda(check your fridge). Then soak the ends of the cables in that solution and watch as the corrosion melts right off. Scrape or wire brush what little will be left.

Still really sounds like it could be an ignition switch issue to me, if you want a write up on how to remove the switch, search for a thread titled "Ignition Switch Removal?" by me. Its kinda of a pain, but if it solves your problems its worth it.
