Are you getting at least 12 volts to the harness on the pump and also is it grounded good? Have you checked the fuse for the fuel pump and the fuel pump relay? Is the ASD relay coming on when you turn the switch to run position? Several more things to check to solve your no start condition.
The fuel pump is located in the fuel tank. On these GM cars, the fuel tank must be dropped in order to change the pump. It is alos recomended that the fuel filter be changed at the same time which is on the frame of the vehicle, left side. the pump at autozone runs about $75 and don't forget the strainer for about $10. The filter runs about$10 also.

Quite a few things can cause a car to die after idling for awhile, but if you have verified that the fuel pressure is actually dropping when the motor dies, the likely culprits are: 1) Electric fuel pump in the gas tank is bad 2) The fuel pressure regulator (on the throttle body) is bad 3) An electrical problem in the power to the fuel pump (like a bad fuel pump relay or lose ground wire to the relay's circuit)
