How much does it cost to replace fuel injectors on a Honda Accord?
For a typical four-cylinder Honda Accord, replacing all fuel injectors generally costs about $700 to $1,100, while the six-cylinder version tends to run roughly $900 to $1,700. These figures cover parts and labor, but final pricing depends on engine type, parts choice, and local shop rates.
Replacement costs vary based on whether you replace all injectors or just one, the quality of parts (OEM vs aftermarket), additional components needed (seals, fuel rail gaskets), and how long the repair takes. A reliable diagnosis is also essential to avoid paying for unnecessary parts if the issue is not injector failure.
Cost estimates by engine configuration
The following estimates differentiate the two most common Accord configurations: a four-cylinder engine and an optional six-cylinder engine. They reflect typical labor times and part prices as seen in U.S. shops.
- Four-cylinder Honda Accord (4 injectors): All-in replacement typically ranges from about $700 to $1,100, including parts and labor. Higher-end pricing occurs with OEM parts and elevated labor rates, while lower-end pricing assumes standard aftermarket injectors and moderate labor charges.
- Six-cylinder Honda Accord (6 injectors): All-in replacement typically ranges from about $900 to $1,700, accounting for more injectors, potentially longer labor, and the choice of parts.
Prices can vary by model year and region, and some shops may quote separate prices for the injectors themselves and for labor. It’s common to replace all injectors at once when one or more fail, to avoid future labor costs for a second job.
What affects the price
The following factors influence the final bill when replacing fuel injectors on a Honda Accord. Consider these when comparing quotes from shops.
- Parts quality and type: OEM factory injectors, refurbished units, or high-quality aftermarket injectors have different price points and warranties.
- Number of injectors replaced: Replacing all injectors costs more than replacing a single injector; some symptoms can be addressed by selective replacement but many mechanics prefer replacing all to ensure uniform performance.
- Labor rates and time: Shop hourly rates vary widely by region; accessibility of the injectors and engine design affect the hours needed.
- Related hardware and seals: New O-rings, seals, seals kit for the fuel rail, and possible fuel rail gaskets add to the cost.
- Diagnostics and ancillary work: Initial fault diagnosis, fuel-pressure testing, and post-repair tests (e.g., leak check, idle learn) may be charged separately.
- Location and vehicle condition: Urban areas with higher overheads and older vehicles needing more work can drive up the price.
Concluding: Shop around and ask for a detailed written estimate that itemizes the injectors, labor, and any additional parts. Also discuss whether a cleaning or reconditioning option is available and appropriate for your vehicle.
Summary
Replacing fuel injectors on a Honda Accord is a substantial repair with costs driven by engine configuration, part selection, and labor. For most four-cylinder models, expect about $700–$1,100; for six-cylinder models, about $900–$1,700. Always obtain multiple quotes, confirm included items (seals, gaskets, testing), and consider whether all injectors should be replaced at once for reliability and to avoid repeat labor costs.
Can you drive a car with bad fuel injectors?
No, it is not recommended to drive with bad fuel injectors, as this can lead to significant engine damage, safety risks, and expensive repairs. A malfunctioning injector can cause poor acceleration, rough idling, and stalling, and could cause a lean or rich fuel mixture that damages the engine, pistons, and especially the catalytic converter. Driving with a bad injector can lead to the vehicle becoming undrivable and may cause the catalytic converter to overheat and fail, which is an expensive repair.

- Engine damage: A faulty injector can cause a cylinder to run too lean, which increases combustion temperatures and can damage pistons and valves. Conversely, a stuck-open injector can flood the cylinder with too much fuel, which can dilute the engine oil, leading to bearing failure.
- Catalytic converter failure: An imbalanced air-fuel mixture can lead to unburned fuel entering the exhaust, causing the catalytic converter to overheat and fail. This is a very expensive component to replace.
- Poor performance: You may experience issues like rough idling, stalling, poor acceleration, and inconsistent engine performance, which can be dangerous in traffic.
- Fuel inefficiency: The engine may use more fuel than usual, and its overall efficiency will be reduced.
- Emissions issues: Improper combustion can lead to increased emissions, which may cause your vehicle to fail emissions tests.
How long do Honda fuel injectors last?
You can expect fuel injectors to last around 50,000 to 100,00 miles. Fuel injectors atomize the fuel into a fine mist through their nozzles. The fuel mist is released into the engine's intake valves and is easier to burn in this form.
How much would a mechanic charge to change fuel injectors?
However, on average, you can expect to spend anywhere from $500 to $2,500 for this fuel injector replacement. Some individual fuel injectors can under $40 each while others are several hundred apiece. As with any vehicle repair, find a reliable mechanic who will provide you with an honest assessment and a fair price.
Is it worth fixing fuel injectors?
A: The impact of repairing a fuel injector on performance can vary. A well-executed repair can restore optimal fuel delivery, leading to improved engine power, fuel efficiency, and overall performance. However, a poorly done repair may result in further issues.
