My first thought would be to check the wiring connection. The sending unit in the tank provides the ground for the gauge. More gas equals more ground potential and a full indication. No ground equals a gauge sitting on empty.

I agree with tenspeed here, the connector is a known failed part on most GM vehicles that is why most pumps come with a replacement connector. If that is not your problem then you will need to remove the sending unit and find out if you damaged the sender while replacing the fuel pump, it is easy to damage one unless you are very careful.
