It sounds like the fuel pump is defective did you use an AC delco? If not that is your problem.

Here is a guide to help you change the pump out and diagrams below to show you how it will be on your car:

I had this problem as well it turned out to be a cheap pump. Once I replaced it with an OEM unit ($210.00 on amazon) the car has never run better.
