i hope im posting this in the right place. well as stated in the title my spedo and tach dont work and i replaced the gauges so i know its not that but im am ordering a new vss, so you think that would fix both problems or just the spedo and if not what are my options ?

 

Did you check your VSS? I am having somewhat the same problem. My tach waorks though, that is just run off the distributor....Have you checked your wiring?

 

oh really? well doyou know what color wire or wires they are ?

 

Indicating year, make and model of your car is helpful. For example, 82-89 Camaros have cable-driven speedos, 90-92 electronic. Firebirds were cable from 82-85 or so, 86+ electric.

well i have a 91 camaro rs

 

Check the bottom of your distributor, and see if the plugs are loose, that is where you get the signal for your tach from.....

The signal for your speedo comes from your ECM...not sure yet how to check that without a handheld scanner....

 

The most common problem for the speedo seems to be the VSS. Check the tail shaft of the trans for it. A search will provide other possibilties.
