There is an easy test to check the gauge.
Take the sending unit wire off and ground it against the block and the gauge should go full hot with the key on. If it doesn't move then the gauge isn't getting a ground from the wire or it isn't getting voltage from the gauge cluster.
It could also be a bad gauge.
