try splicing in a new ground and see if that get the fuel pump running. also you can test it by applying 12 volts to the fuel pump wires themselves. if the pump is ok it should spin right up. if the connections are good and the fuel pump still doesn't run, it may be the pump itself that is bad. verify that its a always grounded switched 12 v style pump before attempting to test. if the ground wire just bolts to the frame or the cab then its a normal grounded system. some of the pump are always live and switched by applying a ground.

SOURCE: 1996 olds 88 won't start
Found this at:
"Stalls, no power window, seats, locks, fuel pump. I had same problemwith my 94 88. Pull back the carpet on the driver side just under thedoor trim. You will find a large wiring harness. Taped to the outsideof the harness will be a ground splice block. If it is corroded,resplice the wires and your car should start and run, and the windows,locks and seats will be back to life as well. There is another groundblock on the passenger side just under the door sill. You might want tocheck that one too, as there may be corrosion there as well. I had toresplice both on my car and everything is back to normal."
Will try it and let you know. This has been a real difficulty.

Testimonial: "emission wiz info helpful, i am trying to locate a wiring diagram at this time any suggestions also air motor works fine with jumper wire from positiv"
I doubt you have a fuel issue if you replaced the pump. Try this to bypass the fuel pump. Spray some quick start or brakle cleaner into the throttle body. If the car still does not start then the problem is ignition related, NOT fuel related. If it does start then go to mitcell1diy online , search. You can get all the diagnoses info there.
