Purney,
Crawl away! Again, I'm not sure on this, but I think the ignition wire AND power wire for the fuel gauge are connected to the same terminal on the key switch. Your test with the wiggling fuel gauge shows you that the key switch IS working. That leaves the wire from key switch to coil as the suspect #1. Before I ripped out wires, I would test it again at the coil, making sure I had the key in the position that made the fuel gauge work!
In regards to the key switch position, I thought ON was a position most folks would automatically assume was OFF...maybe in the vertical plane! I don't remember.
