Help! No power!

I have a 67 Valiant with a newer steering column (has the key in it) and it also has an amp meter and a volt meter. I have owned the car for nearly two years but I rarely drive it.
I went to drive it the other day, after installing a small Holley Fuel Pump on it. After I wired it up (I wired the hot to the fuel sender and grounded it on the frame) and primed the fuel pump, I triend starting it and it wouldnt fire. I checked and discovered that it wasnt getting fuel in the carb. An easy fix I thought. So after taking care of that, I tried starting it again. It turned over for about 5 seconds and then stopped. Nothing, no power at all. No lights, no gauges were moving, not turning over, nothing. Its like there wasnt a battery in it. (battery had a fresh charge).

I was never an electrical guy, even back when I raced at Gainesville in the late 70's-early 80's and I have no idea where to start looking. Any help would be greatly appreciated!
