Frequently asked questions about fuel injector repair & services

Read our answers to questions about fuel injector repair costs, symptoms and more.

What does a Fuel Injector do?

The fuel injectors are part of the fuel supply system of the engine (provided it is a petrol engine), they usually inject the fuel directly into the cylinders, but in some cars the injectors are situated in the inlet manifold. The injectors diffuse the fuel, which then mixes with the air being let into the engine by the inlet valves and, in turn, the spark plugs will ignite the mixture to combust.

What does a fuel injector replacement involve?

  • Mechanic will read the ECU for possible fault codes related to the fuel system.
  • Mechanic will inspect the fuel supply system and the fuel injectors.
  • If necessary, the mechanic will replace the faulty fuel injector.
  • Mechanic will advise if any other parts need to be replaced.
  • Mechanic will inspect the fuel supply system again for any leaks and test drive the car.
  • Mechanic will make adjustments if necessary.

Can I do a fuel injector replacement myself?

Unless you are a qualified mechanic with the required skills, training and equipment to do the job, we strongly recommend a fuel injector replacement is only carried out by a professional mechanic.

What are the symptoms of a faulty fuel injector?

  • When the engine runs rough, with abrupt power peaks.
  • When there are wet patches around the injectors on the outside of the engine.
  • When the 'Check Engine' light on the car's dashboard is on.
  • When the car doesn't perform as well as usual under acceleration.
  • When there is a strong smell of fuel in the engine bay.
  • When the car's fuel consumption is higher than usual.

How long does it take to replace fuel injectors?

The time it takes to replace a fuel injector or fuel injectors can range from under 1 hour to 4 hours, this will depend on a number of factors like your vehicle's make and model, year, and how many injectors need replacing. Select your car at the top of this page for information on job time and cost for your vehicle through ClickMechanic.

How often should I replace a fuel injector?

Over time, the fuel injectors can be affected by dirty fuel which will mean that the injectors can clog up. In turn the injectors will not be able to diffuse the fuel optimally. In most cases it means that the fuel lines or fuel tank have started to corrode. Alternatively, it can be that the fuel filter has become ineffective, not filtering out debris as it should. All of this leads to engine misfires and therefore an engine that does not run smoothly.

Should you experience problems with the fuel supply, then it is advisable to have the fuel supply system and the fuel injectors inspected and, if necessary, have the fuel injectors replaced. Seeing that the fuel injectors are especially prone to deterioration over time they should always be replaced as and when stipulated in the guidelines set out by your car's manufacturer.

Can you drive with a bad fuel injector?

If you suspect there is any issue with a fuel injector or there are concerns about its age or condition, book an inspection with a professional mechanic as soon as possible, driving the vehicle may lead to further complications or damage.

Is a faulty fuel injector an MOT failure?

Yes, if there's visible leak on a fuel injector can lead to an MOT failure. Any leaks in the fuel system will normally lead to an MOT failure, and hence it is possible the same can happen for an injector. However, injectors are usually hidden beneath engine covers which are not removed during an MOT so the chances of an MOT tester being able establish a visible leak with the injectors is small. That said, an issue with an injector will have an impact on engine performance and will likely result in excess emissions, which can also lead to an MOT failure. If you have a faulty injector it is imperative to get it checked and fixed as soon as possible by a professional mechanic. A fuel leak is a fire hazard and can be dangerous.

Is it worth replacing fuel injectors?

Yes, it can be worth replacing fuel injectors if you want to ensure optimal performance of the engine. Fuel injector play a vital role in the engine's combustion cycle and it's important they are in a good condition. Sometimes fuel injectors can be refurbished, which can help reduce the cost in getting any injector issues fixed.

Should you replace all fuel injectors at once?

Yes, in certain cases it can be worth replacing all the fuel injectors at once. Many times an issue with one injector will likely mean that the others will be on their way out too, provided they were all instaleld at the same time. Replacing them all at once therefore can save hassle and money, as if the others go as well in future you'll have to pay for the labour again. That said, many fuel injectors can be very expensive so it's worth weighing up whether the potential money saved in labour outweighs the cost of a whole set of new or refurbished injectors.

How much does it cost to fix a fuel injector?

Fixing a fuel injector by reconditioning or cleaning it can be a lot cheaper than buying a new one, prices for that can range from £50 to over £150 (excluding removal and refitting labour fees). It is worth noting that after testing the injector it may be deemed as too far damaged to be fixed at which point a replacement injector will need to be sourced.

Can leaky injectors be fixed?

Yes, leaky injectors can be fixed. Many times leaks are caused by broken or worn o-rings or injector seals, replacing these can be a first step towards fixing a leaky injectors. Sometimes, however, the injector unit itself may have become leaky at which point the injector will need replacing.

Can you replace just 1 fuel injector?

Yes, you can replace just 1 fuel injector but whether that's advisable will depend on the issue on your vehicle and cost considerations. Often replacing 1 injector may turn out more expensive in the long run. It's likely other injectors will have deteriorated at the same rate as well requiring further replacements in due course as well, meaning that you'll have to pay for the same labour again. However, this will depend also on the cost of the injectors which can be very expensive, you will need to weigh up whether replacing just 1 injector is worth the risk in the long run.

How much does it cost to clean fuel injectors?
