You should here the pump run for a few seconds if you just turn on the key then iT will stop. Then the pump will fire up again when you start it. ON A 1992 THE RELAY WILL ACTIVATE THE PUMP FOR 1.5 TO 2 SECOND IN THE RUN POSITION WITH THE CAR NOT RUNNING.
fuel filter stopped up or fuel pump loosing fire.
Fuel tank. IN THE TOP OF THE TANK UNDER THE BACK SEAT FOR A 2 DOOR AT LEAST.
Look where the fuel line goes into the carb, take the fuel line out of the carb and then the big nut where the fuel line came out of you want to take loose and the filter is behind that nut, watch carefully how it comes out as there is a spring in there.
The fuel filter is located under the car on the passenger side in front of the fuel tank. It is an inline fuel filter that looks like a small can. To replace it, remover the two fuel line connectors from each end and unbolt the bracket. Reverse the proceedures to install. Be sure you have the fuel flow direction going the right way. I have a 1990 Lemans, I assume the 1991 is the same.
It is most likely located on the top of the fuel tank (it's an electric pump). There should be an access plate inside the vehicle located on the floor board under the back seat, otherwise you will need to drop the fuel tank to get at it.
i have a 1990 lemans and it is located under my back seat you flip up the seat bottom and there is a flap of carpet there it may be the same on yours
The fuel pump on a 1991 Pontiac Grand AM is located within the engine bay. Fuel pumps can come in both mechanical and electrical formats and is connected to the fuel lines on the vehicle.
check for broken or slipped timing belt...also fuel filter and fuel pump Also check the orange wire connected to the positive battery terminal. If it doesn't have a good connection the engine will turn over but will not start. Had the same problem with my '90 lemans.
The relay is located on the back side of the fuse box. You have to crawl under the driver's side steering wheel in order to see the relays. The relay in the BLUE socket is it.
Not that I know of. The tank has to come down to gain access to the pump.
Presuming you have the Pontiac V8 engine, it's on the front driver's side of engine, mounted low on side of timing cover, below water pump. Power steering pump is above it, so may be hard to see. Look for fuel lines from tank exiting frame at engine crossmember on driver's side, or follow fuel line from carburetor back to the pump. Best removed from under car.
The gas tank has to come down as the pump is in the tank.
