Digital Dash TACH not working

I just got a GTA today and the rpm gauge is not working. When I turn the key from off to on, but not running, I see all the little rpm lines light up all the way to redline. When I start the car I get no reading at all though. What could be wrong?

I would see if the tach wire coming off the distributor is cut.

Re: Digital Dash TACH not working

None of the wires coming out of the distributor are damaged at all. Is there a tach sensor?

There's no sensor for the tach. It's wired directly to the coil.

I'm assuming the tach should be working if it lights up when you turn the key.
