iPod won't sync to iTunes - Please help! Tried everything

My iPod won't sync to iTunes. I pug it into the computer, the computer recognizes the device. It automatically opens iTunes once it's plugged in. I was able to system restore via iTunes when the iPod was connected and it wiped the iPod. But when I hit sync it doesn't sync. When I hit the sync button for about 5 seconds the wheel will rotate on the iPod screen and say "syncing" but nothing happens on the iTunes side, (you know normally when your iPod is syncing at the top of the iTunes window it will say "syncing" and you can see the process happening as it quickly runs through the new music it is uploading, this doesn't happen.) I tried restarting the iPod and the computer, system reset, I checked in the control panel to make sure the apple device was started, (which it was,) and even bought a new sync cord to be sure. Nothing. Any ideas?
