It's an autometer EGT guage.
The needle is not moving at all.
I didn't install the guage so I'm not sure where to look.
The back light still comes on when I turn the key. I'm not sure if that means the power is still going through.

Where should I look?

 

check the signal wires, if they are fine then the probe is prolly fucked, they are really sensitive.

I tapped my probe with a soft mallet 2x to get it out of the bung and now it doesnt read :-/

 

Where is the probe usually located?
And can i also just get the probe? or I have to buy pretty much whole unit?

 

I am taking it that you bought the car already built? or you dont know that much about yours?

The probe for a EGT is normally on the Number 3 runner on the exhaust manifold near the head

 

You are correct. I bought the car alreayd built.
But how do i even know that my probe is screwed?
Is there a way to check it?
Sorry for too many q's
