Ok well all my gauges in my 1990 Camaro work except for the tach. Instead of the needle sitting to the left like when the car is turned off, it is stuck all the way to the right like a buried speedometer and it does not move whether the car is on or off. Is there anything I should look for that could maybe fix this problem? I just wanna maybe fix my factory tach before I go on down the road later and get an aftermarket one. Thanks guys.

 

You could have it rebuilt or source a wrecking yard replacement cluster if you want to keep it stock. The last time I priced a speedo / tach cluster rebuild it was about $200+-. If that's an option for you, do a web search to locate one of shops that specialize in that.
