Unable to boot up iPod

It's not clear what you are asking. Have a read of this tip from fellow user John Galt: Writing an effective Apple Support Commun… - Apple Community.

As a starter, is the iPod fully charged?

Hello,

It seems like your iPod is probably either completely shutoff or is dead (battery on 0%). An easy fix for this would be to plug in your iPod and see if it wants to charge.
