What You'll Learn
The 2005 Infiniti G35 has two fuel pumps
The fuel pump is a critical component of the 2005 Infiniti G35's fuel delivery system. It is an electric pump that creates the necessary pressure within the fuel lines to deliver fuel to the engine consistently and with enough force to meet the engine's demands under all operating conditions, from idle to high-speed driving. The fuel pump assembly is located inside the fuel tank, which helps to keep the pump motor cool and ensures that the pump can always draw fuel, even when fuel levels are low.
If the fuel pump in your 2005 Infiniti G35 starts to fail, you may experience a sputtering engine, issues with the car stalling, or a loud whining noise coming from the area of the fuel pump access under the rear seat on the passenger side. Replacing the fuel pump typically costs between $90 and $305 for the part, and between $400 and $900 for parts and labor, depending on whether you replace the pump module or the entire assembly, and whether you install it yourself or have it professionally installed.
It is important to note that not every fuel pump will wear out during the service life of a car. However, it is a wear item, and it is important to pay attention to symptoms that can indicate possible fuel pump issues. Preventative maintenance includes keeping your fuel tank at least a quarter full and replacing the fuel filter according to the recommended intervals, which are typically between 30,000 and 60,000 miles.

Symptoms of a failing fuel pump
The fuel pump is an essential component of your car's fuel system, delivering fuel from the tank to the engine. If the fuel pump fails, the car will not run.
- Trouble starting the car: This is a common issue with a failing fuel pump. The car may not start, or it may take a long time to crank before starting. It may also cut out when running.
- Lack of power: A failing fuel pump may cause a loss of engine power, resulting in poor performance. This can manifest as an extreme lack of power under full throttle or intermittent power loss while driving.
- Engine misfires: Engine misfires can be a symptom of a failing fuel pump, especially when the fuel level is low.
- Noise: A whining noise coming from the fuel tank area when the engine is running can indicate a failing fuel pump. This noise is often a precursor to a loss of pressure or total failure.
- Stalling: A car with a failing fuel pump may stall, but it will usually restart after several minutes.
- Long cranking time: If the fuel pump is failing, it may take longer for the engine to crank and start.
- Check Engine light: A failing fuel pump can cause the "Check Engine" light to come on in the car's dashboard.
If you suspect your 2005 Infiniti G35's fuel pump is failing, it is important to get it looked at by a professional.
