If you're looking to replace the fuel pump on your 2007 Chevy HHR, there are a few things you should know. Firstly, the fuel pump is located inside your fuel tank and is powered by a compact electric motor. Its job is to ensure that pressurized gasoline flows to the engine to power the vehicle. While fuel pumps can last for the life of the vehicle, they occasionally fail, and you may need to replace them. Signs of failure include a car that won't start or stalls after starting, a check engine light coming on, or a whirring sound coming from the fuel tank.
Now, onto the replacement process. It's important to disconnect the battery to reduce the chance of a fire. If your pump is inside the fuel tank, there will usually be an access cover that needs to be removed. If your pump is located under the car, you'll need to jack up the car and support it with jack stands before locating and unbolting the pump. Either way, you'll need to disconnect the fuel lines from the pump and be ready to block them to prevent fuel leakage. Once the new pump is installed, reconnect the fuel lines and refuel the tank. Finally, start the engine to test for leaks and ensure everything is functioning properly.

What You'll Learn
Disconnect the battery and secure the vehicle
Disconnecting the battery and securing the vehicle is the first step in replacing the fuel pump in a 2007 Chevy HHR. This is a critical safety precaution to reduce the chance of a fire. Before beginning any work on the fuel pump, it is important to ensure the vehicle is secure and cannot be accidentally moved or started.
Park the vehicle on a level surface and apply the parking brake. If you are working on a slope or uneven ground, chock the wheels to prevent the vehicle from rolling. Place wheel chocks or blocks in front of and behind the driving wheels (the front wheels for an automatic transmission and the rear wheels for a manual transmission).
Locate the negative battery terminal, typically marked with a "-" symbol or a black cover. The battery may be located in the engine bay or in the trunk, depending on the vehicle model. Once located, use a suitable size wrench or socket to loosen the nut on the negative battery terminal. Do not allow the wrench or socket to contact any metal parts of the vehicle to avoid creating a short circuit. After the nut is loosened, carefully disconnect the negative battery cable from the terminal. Ensure that the cable does not touch any metal parts of the vehicle.
If your vehicle has a remote positive terminal in the engine bay, it should also be disconnected for added safety. Locate the remote positive terminal, typically a large red cable connected to the starter or a fuse box. Use a wrench or socket to loosen the nut and carefully disconnect the cable. Again, ensure that the cable does not touch any metal parts of the vehicle.
With the battery disconnected, secure the vehicle to prevent any accidental movement. Place the transmission in park (for an automatic transmission) or in gear (for a manual transmission). Additionally, place blocks or wedges behind the wheels to provide added security against movement.

Remove electrical wires, connectors and fuel lines
To remove the electrical wires, connectors, and fuel lines of a 2007 Chevy HHR's fuel pump, follow these steps:
First, locate the fuel pump. It is usually inside the fuel tank, either placed inside the gas tank or beneath the back seat or carpet. Disconnect the negative battery terminal.
If your pump is inside the fuel tank, you will need to remove the access cover. In some cases, you will need to drain the fuel before removing the access panel. Once the cover is off, you can access the pump and begin disconnecting the wires and connectors.
If your pump is under the car, jack up the car and support it with jack stands. Slide under the car and follow the fuel lines toward the fuel tank. Once you locate the pump, unbolt it and let it drop slowly.
For both types of pumps, you will need to disconnect the fuel lines from the fuel pump. Have some rags handy, as fuel will leak from the connectors. You should also keep a fire extinguisher nearby as a safety precaution.
Once all the electrical wires, connectors, and fuel lines are disconnected, you can install the new pump. Reconnect the fuel lines and put everything back in place. Refill the tank and start the engine to test.
Remember to take appropriate safety precautions when working with the fuel system, as there is a risk of fire.
