Replacing Fuel Pump In 2010 Camaro: Step-By-Step Guide

Replacing the fuel pump on a 2010 Chevrolet Camaro is a moderately complicated job that is best performed by a professional mechanic. The fuel pump is located inside the fuel tank, and to access it, a mechanic will need to either remove an access panel above the tank in the passenger compartment or lower the fuel tank from the vehicle. The process involves disconnecting the battery, removing the fuel pump supply and return hoses, EVAP system hoses, and electrical connections, and then installing a new fuel pump. The average cost for this replacement is between $611 and $1,244, with parts priced between $34 and $755, and labor costs between $140 and $490.

Removing the fuel tank

To remove the fuel tank from a 2010 Camaro, you will first need to disconnect the battery to reduce the chance of a fire.

There are two options for accessing the fuel pump: either through an access panel or by removing the fuel tank. If your Camaro has an access panel, this will be located in the top of the fuel tank, in the passenger compartment. If there is no access panel, you will need to drain the fuel tank and then lower the tank from the vehicle.

To drain the fuel tank, you will need to remove the fuel pump supply and return hoses, as well as the EVAP system hoses, and electrical connections to the pump. Once the fuel has been drained, you can then lower the tank from the vehicle.

Once you have accessed the fuel pump, you will need to remove it from the tank. This involves detaching any reusable brackets and pick-up screens, and then installing them on the new pump. If your fuel system uses an in-line external filter, this should also be replaced.

Finally, before refitting the fuel tank, check the fuel tank straps and fasteners for excessive corrosion and replace as needed.

Accessing the fuel pump

To access the fuel pump of a 2010 Camaro, you will need to remove it from the tank through an access panel above the tank in the passenger compartment. If there is no access panel, you will first need to drain the fuel from the tank and then lower the fuel tank from the vehicle to gain access to the pump.

One way to avoid this laborious process is to cut an access hole under the rear seat on the passenger side. This will save you a lot of time and effort. You can then simply plug the hole with a simple steel square and some silicone, or make a small door to retain access to the fuel pump for future repairs.

If you do need to lower the fuel tank, you will also need to drop the exhaust, driveshaft, and then the gas tank. You will also need to lower the rear cradle, which can be scary—the front bolts come all the way out, and the rear bolts are barely hanging on so you can slide the tank out the front. It is recommended to do this on a lift rather than on the ground.

Disconnecting the fuel pump

Firstly, it is crucial to disconnect the battery to reduce the risk of fire. This is an essential safety precaution when working with the fuel system. Once the battery is disconnected, the next step is to gain access to the fuel pump. On some vehicles, there is an access panel above the fuel tank in the passenger compartment. If such an access panel exists, it needs to be removed to reach the fuel pump. If there is no access panel, the process becomes more involved.

In the absence of an access panel, the fuel tank must be lowered from the vehicle to access the pump. Before doing so, it is necessary to drain the fuel from the tank. Once the tank is drained, the fuel tank can be carefully lowered and set aside, providing access to the fuel pump. At this point, you are ready to begin disconnecting the fuel pump itself.

The fuel pump is connected to various components, including fuel pump supply and return hoses, EVAP system hoses, and electrical connections. These connections must be carefully detached. It is important to note that fuel may still be present in the lines, so have a suitable container ready to catch any spillage. Ensure you are wearing appropriate safety gear, including gloves and eye protection, when handling fuel and disconnecting the lines.

Once all the hoses and electrical connections have been detached, the fuel pump can be carefully removed from its mounting. If there are any reusable brackets or pick-up screens attached to the fuel pump, they should be carefully removed and set aside for reuse with the new fuel pump. After the fuel pump is removed, inspect the mounting area for any debris or damage. Ensure that the gasket or seal between the fuel pump and the fuel tank is in good condition.

At this stage, the fuel pump has been successfully disconnected and removed, and you can proceed to install the new fuel pump by following the manufacturer's instructions or seeking guidance from a professional mechanic. Remember to dispose of the old fuel pump and any fuel residue properly, following local regulations and guidelines.

Installing the new fuel pump

First, gain access to the fuel pump by removing the access panel above the tank in the passenger compartment. If there is no access panel, you will need to drain the fuel from the tank and then lower the fuel tank from the vehicle. Once you have access to the pump, remove the fuel pump supply and return hoses, EVAP system hoses, and electrical connections.

Next, take the new fuel pump and attach any reusable brackets and pick-up screens from the old pump. If the fuel system uses an in-line external filter, it is recommended to replace it at this stage. Now, install the new fuel pump, ensuring all hoses and electrical connections are secure.

Finally, add fuel to the tank and run the engine to test for leaks. Check for fuel leaks or odours before starting or driving the car. If you notice any issues, do not start the car and have it towed to a qualified mechanic for inspection and repair.

Testing the new fuel pump

Electrical Test:

• Check the fuel pump fuse: Refer to your Camaro's owner's manual to locate the fuse box. Find the fuse linked to the fuel pump and inspect it for signs of damage. If the fuse is blown, replace it with one with the correct amp rating.
• Check voltage at the pump: Consult your vehicle's service manual to determine the correct procedure and location for checking voltage. Ensure that the charge leaving the fuse is reaching the pump.
• Perform a voltage drop test: Use a voltmeter to check the power wire for full voltage and verify that the grounding wire is properly grounded.

Fuel Pressure Test:

• Eliminate the filter as a potential issue: Remove the filter and drain excess fuel. Use a rubber hose on the filter inlet and blow through it, checking for minimal resistance. Inspect for debris and replace the filter if necessary.
• Obtain a fuel pressure gauge: These are commonly available at auto parts stores and can be borrowed from some machine or auto shops.
• Attach the pressure gauge: Locate the fuel pump test point near the fuel injectors and the connection point between the pump and the filter injector rail. Attach the gauge, following the instructions in your owner's manual for the specific location and gauge type.
• Rev the engine: With the engine slightly warmed up, check the pressure at idle speed and the rated speed in your pump specifications. If the pressure is below specifications or doesn't increase when you rev the engine, it indicates a problem with the fuel pump.

Additional Notes:

• Keep a fire extinguisher nearby when working on or testing the fuel system.
• If you're uncomfortable with any of these steps, consult a professional mechanic.
• Ensure you have the correct repair information for your specific vehicle make and model.

These tests will help ensure that your new fuel pump is functioning correctly and that there are no leaks or other issues.
