Well, I don't have a UCE bike, but my brother does. The very first thing that happens when you turn the key is you hear the fuel pump. It seems to me if you're not hearing that, then you have a likely suspect. It can crank all day long but never fire if it isn't getting fuel. I'd start by making sure that the your pump is getting power. Check the wiring to the pump with a volt meter. It doesn't sound like the plug is the issue, but I'd try popping in a new plug just to be sure. It's a quick thing to check.
If you can't find the solution easily, just take it to the dealer. It may be 100 miles, but it's under warranty and could save you time in the long run.
