The cost is variable, but is generally around the $300 to $500 mark.
Getting your fuel injectors replaced is part of maintaining your vehicle. The cost of a replacement includes parts and labor. The labor can cost between $200 and $300, while the cost of the parts will vary from $150 to $600.
If you have one or more faulty fuel injectors — due to wear or mechanical or electrical issues, driving for a long time can cause several problems: Stalling or failure for your car to start. Flooding of your engine. Pre-ignition of your fuel.
Yes, it's true that replacing old, worn fuel injectors is an easy way to improve an engine's efficiency. If you have an older vehicle with a set of worn fuel injectors, replacing them will help your engine run like new. You may even notice that your vehicle accelerates better.
The life expectancy of a good quality diesel fuel injector is around 150,000 kilometres. They should be checked out by a professional at around this time.
When a fuel injector is clogged, it needs a concentrated cleaning to resolve the problem. This can be done by a qualified mechanic, or if you know your way around the inside of an engine, you can do it yourself. To start, invest in a fuel injector cleaning kit.
Replacing a fuel injector seems like a daunting project, but with a little skill you can do the job yourself and save serious money. Shops charge a huge amount for fuel injection work. If you know that you have a bad injector, the job can be done at home.
If you've noticed symptoms of injector failure while driving, don't delay! While the risk of severe engine damage is relatively low, it's not impossible. More importantly, replacing a bad fuel injector will improve the fuel economy, engine power, and overall drivability of your vehicle.
Replacing them all at once prevents you from having to get into your engine each time one fails, as well as stopping the headaches caused by multiple failures. You might even have multiple injectors fail at once, making more sense to just replace them all.
Diesel engines work by squirting high-pressure diesel into the engine's cylinders, where it mixes with air and is ignited by a spark plug. These engines need to have plenty of fuel in order to keep running. Running out of diesel will ruin your injectors, so you'd better get some more before that happens!
The customer can look out for a deeper, gravely engine sound, engine chugging, the whole vehicle might have a slight shake or vibration.
Often, one little problem in your diesel engine may be indicative of other system failures. This is why it is often best to replace multiple injectors at once.
Realistically, the tipping point in diesel injectors becoming so expensive was electronic control. In the old days of diesels, fuel injectors had a direct line to a high pressure pump that was timed to the engine.
Replacing a Fuel Injector is definitely not cheap. It will differ quite a bit based on where you live, what brand you want to use and where you install it. But you can expect to pay up to $350. The parts themselves are up to $200 at most, so the rest will be installation and labor related to this process.
The Engine Misfires
Dirty fuel injectors may cause your vehicle's engine to misfire. This problem makes the motor feel as though it is sputtering — sending vibrations through the car. Such misfires can happen when a fuel injector problem mixes up the delicate balance between fuel and air entering the engine.
Although fuel injectors are individual, they are designed to work as part of a team with the other injectors. So, if you're wondering if you can replace just one injector or all, the answer is almost always to replace them all. Typically, the labor to replace one or all of them is the same.
One of the obvious symptoms of a clogged fuel injector is the lighting up of the "Check Engine" light in your dashboard. The fault codes usually associated with a clogged fuel injector can range from misfire codes to lean codes.
Removing injectors without destroying any components can be a simple and easy job with the right tools and an understanding of the system you are working with, although some presentations can be very daunting – especially if there is a build-up of material around leaking injectors or simply the structure of the engine ...
"Fuel injectors have an atomizing nozzle that distributes fuel evenly for optimal combustion and efficiency." Now, a vehicle will typically have one fuel injector per cylinder, with a lifespan of between 50,000 and 100,000 miles, or about 80,000 and 160,000 kilometers.
Even if the entire diesel fuel injection system seems to be faulty, you don't need to replace everything. Fuel injectors are conveniently independent, so you can simply replace the damaged ones.
Ideally, you should thoroughly deep-clean your car's diesel injectors at least once a year or every 30,000 miles. Keep in mind that more frequent cleaning may be necessary if you drive in harsh weather conditions. Another option is to keep the injectors clean by pouring additives in with the fuel.
The Importance of Cleaning Diesel Injectors
If the fuel injectors have deposits, it's important to clean them to restore engine performance back to the way it was. At a professional garage, they may use an ultrasonic machine to clean the injectors out.
“You can definitely delay the degradation process by buying high-quality fuel and changing your filters regularly to prevent debris from getting into the system,” Milne said. “That will prevent the injectors from corrosion or getting worn out faster in high mileage situations.”
