Where is the fuel relay switch (cut off)located on a 1994 Oldsmobile Achieva?

there is an inertia switch but thats only on fords I would check your fuel pressure and scan test for codes

If the car won't start , how are you getting it to autozone to read codes? Did it run before fuel pump replacement and if so , what were the symptoms/reason for replacing the pump? If it didn't run before , was the circuit tested for power and ground while things were apart? That info will help narrow down the poss. causes a little.
