The cost of replacing the fuel pump on a 2007 Nissan Maxima varies depending on location and the type of service centre. The average cost for a Nissan Maxima Fuel Pump Replacement is $472, with prices ranging from $234 to $1,189. This includes parts and labour.

Average cost to replace the fuel pump of a 2007 Nissan Maxima

The average cost to replace the fuel pump of a 2007 Nissan Maxima is between $200 and $1,189, including parts and labor. The cost can vary depending on location and the specific model of your Nissan Maxima.

The fuel pump is a critical part of your engine's fuel line system, moving fuel from the fuel tank to the carburetor or fuel injectors in the engine. A failing fuel pump will not create enough pressure in the fuel system, possibly causing a loss of engine power or preventing the car from starting.

• Whining or humming noise coming from the fuel tank area
• Loss of engine power
• Check engine light is on
• Car won't start or unexpectedly stalls and won't restart

If you notice any of these symptoms, it is important to have your fuel pump checked by a qualified mechanic.

When replacing the fuel pump, it is recommended to also replace the fuel filter and, in some cases, the fuel pump relay. This will help ensure that the fuel system is functioning optimally and prevent future issues.

It is important to note that dealing with the fuel system can be dangerous due to the risk of fire. Therefore, it is generally recommended to hire a professional mechanic to replace your fuel pump.

Parts and labour costs

The cost of replacing a fuel pump on a 2007 Nissan Maxima depends on a number of factors, including location and the type of service centre.

The average national cost for a fuel pump replacement across all vehicles is between $611 and $894, including parts and labour. However, the cost for a Nissan Maxima fuel pump replacement is estimated to be between $234 and $1,189. The parts alone for a Nissan Maxima fuel pump replacement are estimated to cost between $94 and $1,089, while labour costs are estimated to be between $80 and $140 but can go as high as $1,018.

The cost of a fuel pump replacement can vary depending on the additional parts that need to be replaced. For example, a fuel tank hose can cost between $20 and $40, while a fuel filter can cost between $85 and $100. A fuel pressure regulator can cost between $160 and $195, and a fuel injector can cost between $600 and $1,200.

It is important to note that the cost of a fuel pump replacement can also depend on the age and model of the vehicle.

Symptoms of a bad fuel pump

The fuel pump is responsible for delivering fuel from the tank to the engine, so a bad fuel pump will affect this process. Here are some symptoms of a failing fuel pump:

• Whining or whirring noise: A damaged fuel pump may emit a loud, whining noise from the gas tank. Normally, the pump should make a low hum. However, if you hear a louder, more noticeable whining or whirring sound, it could indicate a problem with the fuel pump.
• Trouble starting the car: If the fuel pump cannot deliver enough fuel to the engine, you may experience difficulty starting your car. The car may struggle to start or run due to insufficient fuel being pumped.
• Engine sputtering and stalling: If the fuel pump cannot maintain a constant stream of fuel at higher speeds, the engine may sputter and threaten to stall. This is because the engine requires more fuel to operate under stress, such as when accelerating or driving uphill.
• Engine surging: A bad fuel pump may send too much fuel to the engine, causing it to surge. This results in the vehicle repeatedly picking up and dropping speed without any input from the driver.
• Lower fuel efficiency: If the fuel pump is pushing too much fuel into the engine, you will burn through gasoline faster and need to refuel more frequently.
• Engine overheating: An old or worn fuel pump can cause the engine to overheat due to reduced fuel pressure and insufficient fuel delivery.
• Loss of power: When driving up steep inclines or carrying heavy cargo, you may notice a loss of power if the fuel pump is not supplying enough fuel to meet the engine's demands.
• Check Engine Light: A failing fuel pump may cause the "Check Engine" light to illuminate. This could be due to a slow degradation in fuel pressure and volume, leading to a lean fuel-air mixture and triggering the warning light.

How to replace the fuel pump

Step 1: Disconnect the Battery

The first step is to disconnect the battery to reduce the chance of a fire. Turn off the engine and locate the fuel pump fuse. Pull the fuse out and restart the engine to relieve the engine's pressure. Once the engine dies, disconnect the negative battery terminal.

Step 2: Locate the Fuel Pump

There are two types of electric fuel pumps. The first type is placed inside the gas tank, and the second type is placed beneath the car.

• 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.
• If your pump is inside the fuel tank, it is usually under the carpet or back seat. Pop it open to access the pump.

Step 3: Disconnect the Fuel Lines

Make sure you have someone ready to block the fuel lines, so gasoline does not leak out. Then, disconnect the fuel lines, EVAP system hoses, and electrical connections from the pump.

Step 4: Remove the Old Fuel Pump

If there is an access panel above the tank in the passenger compartment, remove it to take out the fuel pump. If there is no access panel, drain the fuel from the tank and lower the fuel tank from the vehicle to access the pump.

Step 5: Install the New Fuel Pump

Attach any reusable brackets and pick-up screens to the new pump, then install it in the same way that you removed the old one. Reconnect all the fuel lines, hoses, and electrical connections. Refill the fuel tank.

Step 6: Test the New Fuel Pump

Start the engine and check for any fuel leaks. Ensure that the problem is solved and that the engine runs smoothly.

Additional Notes:

• It is recommended to replace the fuel filter at the same time as the fuel pump.
• Unless the fuel filter was recently replaced, a new fuel filter should be installed when replacing the fuel pump.
• It is important to keep the gas tank at least a quarter full after installing a new fuel pump to maximize its lifespan.
• Working with the fuel system is dangerous, so take all necessary precautions to prevent fires.

Average Cost of Fuel Pump Replacement:

The average cost for a Nissan Maxima fuel pump replacement ranges from $234 to $1,189, with parts costing between $94 and $1,089, and labor costing between $80 and $140. Prices may vary depending on location and specific vehicle needs.

How to make the fuel pump last longer

The fuel pump is a crucial component of a vehicle, delivering fuel from the fuel tank to the engine's fuel injection system. While fuel pumps are generally robust, they can fail prematurely due to years of driving and neglect. Here are some tips to help extend the life of your fuel pump:

• Maintain fuel levels: Always keep your fuel pump immersed in at least a quarter tank of fuel. The pump is an electrical device that generates heat, and being submerged in fuel helps keep it cool. Running the tank below this level can cause the pump to overheat and fail.
• Avoid dirty fuel: While rare, gasoline mixed with debris can still be an issue. Try to avoid filling up at a gas station that is simultaneously receiving a fuel delivery, as this can stir up debris and deposits in the stored gasoline.
• Replace fuel filters regularly: Change your fuel filters annually, regardless of mileage or manufacturer recommendations. This will help prevent debris from entering and damaging the pump.
• Use an anti-ethanol agent: Modern fuels are often blended with ethanol, which can cause issues if fuel is left in the tank for extended periods. If you don't use your vehicle frequently, add an anti-ethanol agent to the fuel to prevent fuel system problems.
• Choose high-quality fuel: Opt for high-quality gasoline from reputable stations. This can help reduce the chance of pump failure due to contaminated fuel.
• Avoid running the tank low: Repeatedly running your vehicle with a low fuel level can put additional strain on the fuel pump and shorten its lifespan.
• Regular maintenance: Proper maintenance and care are key to extending the life of your fuel pump. Consult your mechanic or the vehicle's maintenance schedule for guidance on fuel pump care.

By following these guidelines, you can help ensure that your fuel pump lasts longer and reduce the likelihood of unexpected failures.
