If it is loud (louder than other GM cars of the same era with fuel injection) I'd suggest you get it replace BEFORE you are stranded. Running out of fuel damages the fuel pump. They all do make some noise, but the noise is not "loud" Sometimes the baffels in the tank break and pieces of the baffels lodge in the fuel pump.
All fuel pumps make some noise. If the noise is much louder than other fuel injected cars your fuel pump is defective. Fuel pumps that make noise normally fail before long.
Fuel pump in a Fiero is electric. It's in the gas tank. Gas tank's in the middle of the car. Drop the tank. Pull the pump.
the fuel pump is in the fuel tank. you can access to it by the top of the fuel tank once it's removed.
The Fiero Fuel Pump Pulsator is located in the fuel tank connecting the fuel pump to the tube leading out to the engine. It has a rubber insert that connects both tubes (the pump being one of them) It is supposed to smooth the fuel flow but many have yet to determine a difference if it is removed.
the fuel tank has to be dropped from the car to access it.
AC and fuel pump are the same relay
all fieros have it in the gas tank
Most likely
inside the gas tank
All Fieros have the fuel pump inside the fuel tank By the way you may be having trouble because there was no fiero in 1977, production was from 1984 to 1988 so your car is probably a 1987
If the fuel pump is bad it will just quit pumping gas, the electric fuel pump always makes a little noise when running.
is the noise coming from the new fuel pump (in the tank)? if so the new fuel pump is bad
