You may have a ground short somewhere.  The gages and the volt/fuel gage lights have separate power leads routing back to one source, the ground for the entire dash however only has one source.  It is located on the driver's side next to the courtesy light under the dash.  You also need to have the large U shaped bracket, under the steering wheel, installed because the ground runs through it as well - if you don't you will have weird things going on. 

Here is a link to very thorough write up on the dash wiring. http://www.firebirdtransamparts.com/techinfo/harness/harness.htm

I hope you get it fix. Let us know what you find out.
