My tach quit working

[socmninja]

So I'm driving to work and shifting kind of hard and I look down at my gauges and my tack needle is sitting on zero. I know it was working when I started the car and was driving earlier but I didn't notice it go dead. When I get to work I turned the car off, removed the key, then restarted and still, needle sitting on zero. I decide to mess with it later and go to work. At the end of the day, I start the car up and it works. Has anyone ever had this happen to them?

get aftermarket tach like auto meter cause the stock one is to slow to keep up the ls1 with mods from what i can tell!!

It could be the wires, did you inspect the electricals at all?? I am not familiar with these cars but with my chevy truck, it was a wire that was the culprit.

yep, found it. the #10 wire coming out of my pcm where I tapped in to my shift light was loose
