That sounds like the stepper motor that moves the needle in the cluster has failed. There are places that will rebuild the cluster but it can cost as much or more than a used cluster in an older vehicle. Being a 1993 it will not interface with the cheaper scan tools that work on 1996 and up cars. You need the older system that Toyota used to be able to verify that the tachometer is getting the correct signal prior to removing it for repair.
