I have a 2005 Z71 Tahoe the oil pressure guage is not working could this be the guage or the sending unit?

More than likely the sending unit. Get it replaced.

Yep, Agree with Snake.... the sending unit as gone bad. Hard to get to, but easy to replace. It is behind the motor right by the firewall on the left side/drivers side of center
