Your Saturn car’s fuel pump is what pressurizes the gasoline in the fuel tank and sends it to the fuel injectors and then the engine to burn. If you are having problems while driving your Saturn car, such as sudden bursts of acceleration when steadily pressing the accelerator pedal or if the fuel pump is rattling and / or leaking, then the pump may be faulty and should be replaced. This is a task that requires additional and more advanced knowledge of automotive repair, specifically fuel and exhaust systems.
How to change a fuel pump in a 1997 Saturn
Drive your Saturn to the car ramps and park the vehicle. Remember to set the parking brake to avoid possible slipping or sliding.
Climb under the vehicle and locate the fuel pump. Follow the fuel line from the tank as the line bends at a 90 degree angle and approaches the motor car. Look for a small cylindrical part sticking out of the fuel line, accompanied by brackets on both sides and a valve on the side of the tank.
Turn the fuel line valve near the fuel pump clockwise with a wrench until it is tight. This will close the fuel line to the gas tank.
Use a 12mm socket wrench to remove the electrical connection from the pump. This is secured with a simple bolt.
Place a bucket under the fuel pump to catch any excess gasoline that drips. Use the wrench to loosen the sides of the bolt at both ends of the pump. Finish loosening the sides of the bolts while holding the pump. Gently place it in the bucket as excess fuel drains into the line.
Slide a new replacement pump into place and re-secure the bolt sides. Hold them firmly with the wrench.
Replace the electrical connection, once again using a 12mm socket. Open the gas valve behind the pump with the wrench.
Get out from under the vehicle and off the ramps. Remember to first remove the parking brake.

Jack up the Saturn 2000. Lower the vehicle onto jack stands.
Remove the rubber washer around the top of the fill tube. Use a socket wrench to remove the screw under the washer.
Disconnect the fuel tank sensor and the fuel pump unit. These two cables are located under the car, just above the fuel tank.
Disconnect the fill tube with a socket wrench. Use a ratchet to release the clamps.
Remove the fill tube. It should slide off once the clamps are removed.
Disconnect the filter / pressure regulator, located near the fuel tank, and slide it out of the way.
Support the fuel tank on a block of wood using the floor jack to hold it in position directly under the tank. This will prevent the tank from falling over and cracking.
Remove the retention straps holding the tank in position with a socket wrench. Lower the tank carefully.
Loosen the lock ring on the top of the fuel tank with a brass punch. Do this carefully to avoid damaging the part, hitting the ring counterclockwise.
Take the old assembly out of the tank and place the new one inside.
Reassemble the fuel tank and secure it back on the 2000 Saturn.
