When to Replace the Fuel Pump – Common Signs & Symptoms

About the fuel pump:fuel-pump

The fuel pump is responsible for delivering fuel from the petrol tank, through the fuel injectors and into your engine. This allows your engine to burn the fuel. For optimum engine performance, the fuel pump must deliver fuel at the appropriate pressure. Too much or too little pressure will affect the air/fuel ratio of your engine and affect running conditions.

Learn more about how the fuel pump works

The fuel pump is usually an electrical component located inside the fuel tank. However, some fuel pumps are inline or mechanically operated. If the fuel pump fails, it can prevent fuel from reaching your engine. If this happens, it will need to be replaced for your cars engine to run properly again.

 

How long does a fuel pump last?

The fuel pump is built to last a long time. In fact, it can last for well over 200,000 km of driving. For this reason, mechanics will recommend that the fuel pump should only be replaced if it breaks.

After 150,000 km, the chance of failure becomes likely enough that mechanics will often recommend replacing the fuel pump if you are replacing a major part of your fuel system nearby. This cuts the costs of labour in the event that the old fuel pump fails shortly after.

 

Symptoms of a failing fuel pump:

Before the fuel pump fails, it will often show a few symptoms:

  • Whining noises – You may notice a loud whining noise from the fuel tank. This is a common sign of a failing fuel pump and can be caused by a damaged fuel pump or contaminated fuel.
  • Sudden losses of engine power – One of the most common signs of a faulty fuel pump is the engine stuttering, particularly at high speeds. This happens because the fuel pump cannot provide a consistent flow of fuel to your engine.
  • Sudden surges in engine power – Surging is a random increase in engine power. It can occur due to a faulty fuel pump starving the engine for fuel and then delivering the correct fuel to the engine.
  • Check engine light on – A faulty fuel pump may deliver too much / too little fuel to the engine. This can affect its air/fuel ratio, causing the check engine light to illuminate.
  • Car not starting – When the fuel pump has failed, it will no longer be able to deliver fuel to your engine. This will result in the car’s engine not starting when the keys are turned. Or the engine may start then stop shortly afterwards.
