The fuel injector in a 2010 Honda Accord is a vital part of the car's engine, delivering fuel directly into the cylinders to suit the current load demand for the right mixture of air and fuel. Fuel injectors are usually connected to a fuel rail located on top of the engine, which is supplied with fuel under pressure from the fuel pump in the fuel tank. This process is controlled by the powertrain control module (PCM), which controls the solenoid's on time to keep the air-fuel ratio optimized. When a fuel injector fails or clogs, engine power is reduced, and the car may stall or accelerate unpredictably.

What You'll Learn
Fuel injector replacement cost
The fuel injectors in a car regulate the amount of pressurised fuel used for each engine cycle. There is one injector per cylinder in an engine. Each time an intake stroke occurs in the engine, the vehicle's computer sends a signal to the fuel injectors, requesting that they spray fuel. Fuel injectors tend to fail after 80,000 miles and require little maintenance.
If you notice any fuel odour around your car, a leaking fuel injector could be the cause. There should be no external leak from a fuel injector. If an externally leaking injector is suspected, do not start your car due to the fire hazard.
The average cost for a Honda Accord Fuel Injector Replacement is between $679 and $819 but can vary from car to car. This job may involve draining the coolant and oil, removing many engine components, and replacing the intake manifold gasket. Some cars are designed with plastic intake manifolds that do not have oil or coolant passages, making this process easier. Once access is available, the fuel injector is disconnected from the fuel rail and electrical connector and removed. The new one is then installed in its place.
To prolong the life of the fuel injectors, follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors. Using a fuel injector cleaner regularly is a smart move to stop problems later on. These cleaners get rid of the gunk that builds up over time and can block or harm the injectors.

Fuel injector failure
Fuel injectors regulate the amount of pressurised fuel used for each engine cycle. There is one injector per cylinder in an engine. Each time an intake stroke occurs in the engine, the vehicle's computer will send a signal to the fuel injectors, requesting they spray fuel. For heavy acceleration, the duration of the fuel spraying will be longer than if the engine were idling.
Fuel injectors can last the life of a modern vehicle with little to no trouble. However, bad fuel injectors are one of the more common issues that happen to any vehicle, including the Honda Accord. Even one bad injector is enough to impact the drivability of your car.
There are two main ways that your injectors can fail to do their job properly. The first is for them to become clogged, dirty, or unresponsive. When this happens, not enough fuel enters your Accord’s combustion chamber. The other way is if the injectors are leaking. When they leak, they can cause significant issues.
When a fuel injector isn’t functioning properly, it can cause problems such as misfiring cylinders, the check engine light turning on, a vibrating engine, and a bad fuel odour at idle. In some cases, engine stalling can also occur. These issues can lead to decreased performance and potentially more severe engine damage if left unaddressed.
If you are experiencing fuel injector failure, it is recommended to visit a professional mechanic. Fuel injector replacement should not be a DIY job as there is a risk of fire, and the repair process can be complicated. The average cost for a Honda Accord Fuel Injector replacement is between $679 and $819, but this can vary from car to car.

Fuel injector cleaning
Fuel injectors regulate the amount of pressurised fuel used for each engine cycle. There is one injector per cylinder in an engine. Each time an intake stroke occurs in the engine, the vehicle's computer will send a signal to the fuel injectors, requesting they spray fuel.
Fuel injectors for the 2010 Honda Accord can be purchased online. However, replacing them is a complex task that should be left to a professional. The average cost for a Honda Accord Fuel Injector replacement is between $679 and $819.
Fuel injectors tend to fail after 80,000 miles and require little maintenance. To prolong the life of the fuel injectors, follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors.
To clean the fuel injectors, you can use a fuel injector cleaner. However, opinions vary on the effectiveness of these products. Some people recommend using a good additive package that's blended into fuel. Top-tier fuel from major brands such as Shell, BP, and Mobil 1/Exxon contains a good cleaning additive.
Others argue that fuel treatment products are unnecessary for modern cars and that pump gas has all the additives your engine needs.
If you do choose to use a fuel injector cleaner, you can pour it into your gas tank or, if you have the right equipment, put it directly into the injectors. You can also disconnect the line to the fuel tank and put a bottle of injector cleaner straight into it while the engine is running.
It is important to note that fuel injector cleaners should not be used as a substitute for proper maintenance and repair. If your vehicle is experiencing fuel delivery system symptoms or frequent misfires, a technician should inspect the vehicle to diagnose and address the issue.

Fuel injector replacement procedure
The fuel injector in a 2010 Honda Accord is usually connected to a fuel rail located on the top of the engine. The fuel rail, in turn, is supplied with fuel under pressure from the fuel pump located in the fuel tank. The injector has a solenoid and valve within, and the operation, or pulsing, of the solenoid is controlled by the powertrain control module (PCM). The PCM controls the solenoid's "on" time to maintain an optimal air-fuel ratio as the engine load and operating conditions change.
To replace the fuel injector, the engine oil and coolant may need to be drained, and several engine components, such as the intake manifold, fuel rail, and other components, may need to be removed. It is important to note that this process can vary depending on the car's specific design and that incorrect removal can damage the vehicle. Therefore, it is recommended that fuel injector replacement be left to a professional due to the complexity of the repair and the risk of fire when working with fuel.
When replacing the fuel injector, it is essential to use high-quality, OEM parts to ensure even power distribution across the engine and a proper air-fuel mixture for all cylinders, resulting in smooth engine operation. The battery should be disconnected, and proper fire safety precautions should be taken.
The general procedure for replacing a fuel injector is as follows:
- Disconnect the battery and take proper fire safety precautions.
- Drain the engine oil and coolant, if necessary.
- Remove the necessary engine components to access the fuel injector, such as the intake manifold and fuel rail.
- Disconnect the fuel injector from the fuel rail and electrical connector, and remove it.
- Install the new fuel injector in its place, ensuring proper connections.
- Reinstall the fuel rail, supply, and return lines, plenum, and any other removed components.
- Reinsert the injector into the fuel rail using a new O-ring and engine oil to prevent damage.
- Run the engine and carefully check for leaks.
- Road test the vehicle to ensure proper functioning.
It is worth noting that fuel injector replacement may be necessary due to issues caused by a recalled fuel pump in some Honda Accord models. Additionally, fuel injector servicing, which involves cleaning and replacing the internal filter baskets, can be performed to maintain injector performance. However, this should only be done using methods and compounds specified by the manufacturer, as on-car cleaning may be ineffective due to the tiny internal filter baskets.
