What seams to be the problem Jessica ? No fuel ? This vehicle has no inertia fuel cut off switch ! I 'm looking at a wiring diagram for this vehicle, there is a fuel pump relay in the under hood fuse / relay box . In the instrument fuse box is a fuse marked F/P-INJ. fuse 15amp.this supply's power to the fuel pump through the fuel pump relay. If you knew how to do it you check for power at the fuel pump relay ! GM Fuel Pump Relay Testing
Sounds like a short between the fuse panel and the fuel pump relay. This can be from the fuel pump relay itself through an exposed bit of wire, or even a defective relay which seems to happen more than most times. Check the wiring to the relay and wrap or tape anything where bare wire may be exposed. Disconnect relay and try a new fuse. IF the fuse doesn't blow, then the problem source is the relay itself that is defective.
The fuel pump relay is located in the fuse junction block,under the hood
on the left fender. There is also a fuel pump+injectors fuse, in the fuse
block behind the left side of the dash. It should be marked f/p-inj.
Hope this helps.
