I took my car out for the first time this year and my tach is not working. Over the winter I had my computer retuned for more boost and cleaned up a coupled things under the hood. The car runs good other then the tach not working. Can anyone point me in the right direction.

 

Does it twitch when you turn the Key on?

 

I did not notice it twitch. I'll check again but I think it does not move at all.
