Replacing The Fuel Pump In A '96 Chev Calaviler

If the fuel pump in your 1996 Chevrolet Cavalier is acting up, it may be time for a replacement. The fuel pump is responsible for delivering gas from the fuel tank to the fuel injectors, ensuring the engine runs smoothly. While it's not an easy task, with the right tools and safety precautions, you can replace the fuel pump yourself. Before you begin, make sure you run your fuel almost out, as you'll need to store the remaining gas outside the fuel tank while you work. Disconnect the battery to reduce the risk of fire, then drain the fuel tank and remove it from the vehicle. You'll need to remove the fuel pump assembly and disconnect the electrical connectors before installing the new pump. Finally, reattach the fuel tank, reconnect the battery, and verify that there are no fuel leaks.

Disconnect the battery

Disconnecting the battery is the first step in replacing the fuel pump on a 1996 Chevrolet Cavalier. This is a crucial safety measure to reduce the chance of a fire when working on the fuel pump.

Park your car on a flat, level surface before disconnecting the battery. This is important to ensure the car remains stable while you work on it. Once parked, locate the battery and identify the positive and negative battery terminals. You will need to disconnect the positive terminal. You can do this by loosening the clamp that holds the cable to the terminal with a wrench and then removing the cable. Ensure that you do not allow the cable to touch any metal parts of the car, as this could cause a short circuit.

After disconnecting the battery, you will need to siphon the gas from the tank. This is because the fuel tank needs to be removed to access the fuel pump. Place the siphoned gas into an approved container and ensure that you follow all necessary safety precautions when handling gasoline.

Once the fuel tank is empty, you can proceed with removing it from the vehicle. Place a drain pan underneath the tank to catch any remaining fuel or debris. Then, locate the bolts that secure the fuel tank to the vehicle and remove them using a socket wrench. Lower the fuel tank carefully and place it on a flat surface. You may now proceed with removing and replacing the fuel pump.

Remember to reconnect the battery terminal once you have completed the fuel pump replacement and refilled the fuel tank.

Drain the fuel tank

To drain the fuel tank of a 1996 Chevrolet Cavalier, first ensure that you run your fuel almost out before you start. You will need to store the remaining gas outside of the fuel tank while you work, so it must fit into a storage container. If you start to siphon out the gas and the container is not large enough, you will end up with gas everywhere.

Park on a flat, level surface and disconnect the positive battery terminal. Place mechanic’s ramps behind the rear tires of the car. Siphon out the gas tank and let it run into the empty gas can. If you purchased a siphon, it will have instructions on how to use it. Read these and follow them. Remove the gas from your vehicle into the gas can.

Push your car backwards up onto the mechanic’s ramp to give you access to the underside of the fuel tank. You have to do this after you have removed the fuel, or you will not be able to get all the fuel out of the tank. Use the creeper and roll under the back of the car to the fuel tank. It is a large black tub under the back seat.

Two metal straps hold the tank to the frame. Use a socket wrench to unbolt it from the car. As it is empty, it will be lightweight enough that when it starts to drop, you can leave it on your chest for a moment. You need to be able to disconnect the wiring before you can place it on the ground.

Push the white buttons on the fuel lines and the wiring harness to disconnect them. Once the tank is disconnected, you can pull it out from under the car.

Remove the fuel tank

To remove the fuel tank from a 1996 Chevy Cavalier, follow these steps:

First, ensure that you run your fuel almost out before you begin. You will need to store the remaining gas outside of the fuel tank while you work, so ensure you have a suitable storage container. Park on a flat, level surface and disconnect the positive battery terminal. Place mechanic's ramps behind the rear tires of the car.

Next, siphon out the gas tank and let the fuel run into the empty gas can. Push the car backwards up onto the mechanic's ramp to access the underside of the fuel tank. Use the creeper and roll under the back of the car to reach the fuel tank. It is a large black tub located under the back seat.

The fuel tank is held to the frame with two metal straps. Use a socket wrench to unbolt it from the car. As it is empty, it will be lightweight, so when it starts to drop, you can leave it resting on your chest momentarily. Disconnect the wiring before placing the tank on the ground.

Push the white buttons on the fuel lines and the wiring harness to disconnect them. Once the tank is disconnected, pull it out from under the car.

Disconnect the fuel lines and wiring harness

Disconnecting the fuel lines and wiring harness on a 1996 Chevrolet Cavalier is a relatively straightforward process, but it requires careful attention to safety. Here is a detailed guide:

First, ensure that you have run your fuel almost out before beginning the process. You will need to store the remaining gas outside of the fuel tank while you work, so make sure you have an empty gas can or container that is large enough to hold the fuel. Park your car on a flat, level surface and disconnect the positive battery terminal.

Next, place mechanic's ramps behind the rear tires of the car. Siphon out the gas tank, allowing the fuel to run into the empty gas can. Follow the instructions on the siphon if you are using one.

Now, push the car backward up onto the mechanic's ramp to access the underside of the fuel tank. Use a creeper to roll under the back of the car to reach the fuel tank, which is a large black tub located under the back seat.

The fuel tank is held to the frame by two metal straps. Use a socket wrench to unbolt the tank from the car. As the tank is empty, it will be lightweight, so you can let it rest on your chest momentarily.

At this point, you can disconnect the fuel lines and wiring harness. Look for white buttons on the fuel lines and wiring harness, and push them to disconnect.

Once the tank is disconnected, carefully pull it out from under the car. Clean off the top of the tank and proceed to remove the fuel pump.

This process requires careful attention to safety, especially when dealing with flammable liquids and working under a vehicle. It is always recommended to consult a certified mechanic or automotive professional if you are unsure about any steps or procedures.

Install the new fuel pump

Now that you have removed the old fuel pump, it's time to install the new one.

First, install the fuel pump outlet seal, then slide the fuel pump outlet into the slots of the reservoir cover. Next, install the fuel pump and baffle assembly onto the reservoir retainer and rotate it clockwise until it is seated.

Now, install the lower retainer assembly partially into the reservoir. Line up all three sleeve tabs. Press the retainer onto the reservoir, making sure all three tabs are firmly seated.

Gently pull on the fuel pump reservoir from the retainer to assure a secure fastening. If it is not secure, replace the entire fuel sender.

Attach the fuel pump connector and fasten the CPA connector to the fuel sender cover. Install a new external fuel strainer.

Finally, install the modular fuel sender and the fuel tank into the vehicle.
