Celebrity Fuel Problem 2.8l

ok, i have an 1989 chevrolet celebrity with the 2.8l sedan. And i think i have a fuel problem. The car ran fine for a while but it would surge at a light and stall. It would start right back up with no problems. Then eventually i would hear a hummmmm noise coming from the rear of the car. And i would sometimes smell gas. Well then it wouldent run period. So i changed the fuel filter no change. sometimes it will run idleing, no more than that if you hit the accelerator it dies. And when i turn the key i hear the fuel pump go eerrrrrrrrr then it dies very slowly, so my guess is the fuel pump. what do you think.

change the pump and check the gas line from the rear to the front for any wetness
