Fuel pump

Your vehicle's fuel system consists of many different parts, from injectors to fuel pumps, fuel tank sending units and plenty of other parts which all need to be kept in good working order. A fuel tank sender unit consists of a float and sensors to work out how much fuel you have left in your tank and then sends this info to the fuel gauge on your dashboard. A fuel pump is present in most modern engines and feeds fuel through to your engine. Depending on your engine type, you'll need a fuel pump that delivers fuel at either low or high pressure. Fuel pump replacement is very important. If the engine does not have a functioning fuel pump, it will immediately “starve” and stop functioning. Electric fuel pump emits high fuel pressure to supply electronic fuel injection to the system. The fuel is extremely pressurized to produce power.

A malfunctioning fuel pump tends to deliver too much or too little fuel from the petrol or diesel tank, which can cause your vehicle to breakdown. To ensure your vehicle always drives as it should. Mechanical fuel pumps resemble diaphragms and sit on a mount outside of the fuel tanks of older vehicles. Most modern vehicles use an electronic fuel pump, which you will find in the fuel tank itself. Whereas electronic variants deliver greater performance, they are prone to more issues. This is because both the pump and the computer that your car uses to control it can malfunction. There are a few symptoms of a faulty fuel pump to look out for. If your vehicle sputters at high speed or loses power while under stress or even just when you accelerate, these are key signs that you need to replace the pump in your car. If your car suffers from any of these symptoms, get it checked and change your fuel pump as soon as possible to avoid costly repairs. As a vital part of the fuel delivery system, buying a good quality fuel pump will help ensure that your car continues to run smoothly.

The fuel pump is part of the engine's fuel system and serves to supply fuel to the engine for combustion at the level required by the engine. In most cars, the pump is usually located near or in the fuel tank.

Over time, due to continuous use, the fuel pump can wear and eventually fail leading to an unstable flow of fuel being directed towards the engine. Depending on whether the car has a mechanical or an electronic fuel pump several issues can arise. Sometimes it can be that the fuel pump does not pump an adequate amount of fuel to the engine, causing the engine to sputter, with the car slowing down and speeding up constantly. Similarly, it can be that the car suddenly surges forward when driving at a constant speed. It usually means that parts of the pump have worn or that its electrical and elements connections let through an irregular current. In other cases, a fuel pump can malfunction completely, which means that no fuel is pushed to the engine, as a result the engine will not start or cut out.

A faulty pump with low pressure will disturb the engine's air-fuel ratio, which can cause all sorts of performance problems. Aside from hard starting, the vehicle may experience misfires, a loss in power and acceleration, a decrease in fuel efficiency, and even engine stalling.

  • How do you know there is something wrong with a Fuel Pump?
  • When the engine runs rough.
  • When the 'Check Engine' light on the car's dashboard is on.
  • When the car has performed unreliably under acceleration.
  • When there is a whizzing noise coming from near the fuel tank.
  • When starting the car is troublesome.
  • When the car leaks fuel.

There is really no reason to pre-emptively replace the fuel pump before 100,000 miles. Fuel pumps have been known to last for over 200,000 miles in some cases.

Insufficient flow limits cooling and lubrication of the pump. A leading cause of fuel pump failure is running the fuel tank low. This is particularly critical on late model vehicles without a fuel pressure return system. Running such a vehicle out of fuel once can permanently damage the fuel pump.

A faulty pump with low pressure will disturb the engine's air-fuel ratio, which can cause all sorts of performance problems. Aside from hard starting, the vehicle may experience misfires, a loss in power and acceleration, a decrease in fuel efficiency, and even engine stalling.

Usually a bad or failing fuel pump relay will produce a few symptoms that can alert the driver of the issues. One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls. Engine does not start. No noise from the fuel pump. Can a bad battery cause fuel pump to not work? Many driveability and starting problems that are charging, starting or ignition related may be due to low battery voltage. Low battery voltage can also affect fuel delivery by causing the fuel pump to run slower than normal. This, in turn, causes, low fuel pressure and a lean fuel condition. Can running out of fuel damage fuel pump? Running a fuel engine out of fuel doesn't hurt the engine, but it can have negative effects on the fuel pump. If you run out of fuel, the fuel pump isn't being cooled anymore and you can damage the pump. Fuel pumps are in the fuel tank in most cars these days.

Maintaining the heat in your car's engine can also possibly be the solution for the need of starting your car with bad fuel pump. The main reason why your car starts, even with a bad fuel pump is that once the car gets cool, the fuel pump resets itself without the required pressure and heat. What are the symptoms of having air in the fuel line? Symptoms of a Bad or Failing Fuel Return Hose Strong fuel smell, engine misfires, and decreasing power. One of the first symptoms of an issue with the fuel return hose is an excessive fuel smell. Carburettor flooding, engine stalling, and hard starting. Another symptom of a potential problem with the fuel return hose is carburettor flooding. Can a fuel pump be weak? A weak fuel pump may still pump fuel however, the vehicle may have trouble starting because of the lack in pressure. Can a clogged fuel filter cause fuel pump failure? If the fuel filter is clogged, the flow of fuel will be reduced or even stopped. The filter should be cleaned or replaced, if needed. A clogged fuel filter will cause your vehicle to struggle while starting. Other engine problems due to a faulty fuel filter include backfiring, stalling and hesitation. Will fuel pump stop car from starting? It is a simple fact of life that if the fuel pump stops working the car will stop moving. It is the fuel pump that sees to it that fuel gets from the tank to the engine. While it is possible to run on a failing fuel pump for a certain distance it will sooner or later no longer operate.

Sometimes, the worst part of getting your car fixed is having to bring it to the garage. We are therefore happy to offer our customers a free collection and delivery service If you prearrange a collection, we will pick your car up from your home or place of work and drive it to our premises, carry out all the necessary work (having consulted you) and deliver it back to you at the end of the day.
