I figured it out last night. I had the battery sitting outside the vehicle connected via jumper cables to the terminals in the car.
Additionally, I had not bolted back on the battery housing (metal). This was mainly done as the starter is very difficult to access on the mdx. So didn't want to put everything back together until I could verify it worked. I did of course ensure I had all the cables connected. Anyway, so I put everything back together and the engine started without a problem. Maybe it was missing a ground due to all the metal housing not connected back - I am not really sure. Maybe just chalk it up to being a newbie :-)
