1999 Saturn SL1 Electrical fuel pump.

Last week, my car did not work. It can start, engine had no problem. But then it can not move even you step on the gas. The I found a guy fix the car. He checked it and said it was the fuel pump's problem. So I order a new fuel pump and fuel filter in autozone. The guy fixed it and the car could move again. But just one week. The same problem happed again. The situation is similar with the last time. Engine can start, but no fuel in the tank. The guy who fixed it checked it again and said the fuel pump broke again. He said the fuel pump from autozone is in low quality. I do not know what happened?
