Possibly the harness or connector got messed when the pump was changed. The same harness feeds the pump and gauge. Or, you are the latest victim of 'corrosive fuel' according to TSB GM. http://www.grandamgt.com/forum/showthread.php?t=22264 Changing out the sending unit is easy, but check the harness first.
