If there's no power going to the sending unit, that has nothing to do with the dash guage, the guage reads what the sending unit tells it. If it doesn't tell it anything, the guage will stay blank. You seem to have a seperate issue. You can start by checking fuses, which you probably should have done first, and then by checking relays and then wiring.
