50Chevyguy,
I apologize for misleading you. My recommendation to check the ground wire was in response to the original post. A "pegged to Full" gauge is often a bad ground at the sender.
I read your post too quickly and assumed it was the same symptom as the original post.
Did you ground the gauge-housing to see if the instrument lights work?
As far as you getting no reading: it could be a bad gauge, a bad sender, or a break in the lead from the gauge to the sender.
Do you have the power lead going into the correct side of the gauge (the "E" empty side of the gauge, I think?
