11998 Ford Contour fuel problem

We may have to do this one in a few steps.
1. Does the car stall when it is not in gear or no load on it?
2. Have you had anyone check the fuel pressure?
3. What was reason for changing fuel pump?
4is there a check engine light on? If so you need to have it scaned to find out what the codes are and thayt may give you an idea what is wrong. Start whit these questions first and reply I will get message and answer back. I really need this info to give you the best answer possible.(NOS) 8)
