The fuel injector makes sure that the right amount of gasoline is fed into the cylinders at the right time. Here’s how to detect if your fuel injectors need to be replaced and how much it will cost.
A fuel injector is an important part of practically every contemporary car’s fuel injection system.
A fuel injector is responsible for providing gasoline to the car’s engine, and a malfunctioning fuel injector can create a slew of issues.
In this article, we’ll go over the fundamentals of a fuel injector, as well as how to diagnose problems and take preventative measures to extend the injector’s life. Let’s start with the signs:
A misfiring cylinder and a check engine warning light on your dashboard are the most prevalent symptoms of a broken fuel injector. At idling, you might notice a shaking engine or a strong gasoline odor. It could also be a sign if your engine stalls at idling.
Because the fuel injector is directly related to the engine, any issue with the fuel injector will cause the vehicle’s performance to suffer.
Here’s a more in-depth look at the most prevalent signs and symptoms of a damaged or defective injector.
The flickering check engine light on your dashboard is one of the most noticeable indications. An electronic signal is delivered to advise the driver if one of the fuel injectors is clogged or unclean and is not efficiently giving fuel to the engine.
Please keep in mind that the check engine light might come on for a variety of reasons. As a result, you should take your vehicle to a mechanic and have it scanned for fault codes.
Check your fault code memory with an OBD2 code reader if your check engine light flashes. They are inexpensive, and you may read the fault code memory from the comfort of your own home.
The engine will begin to vibrate as soon as it has completed a full cycle if it is not receiving enough fuel. A clogged or filthy fuel injector in a turbocharged engine can cause severe detonation, which can destroy the engine.
When the engine is in turbocharged mode at a higher rpm, it uses a lot of gasoline, and if the fuel injector can’t keep up, detonation might happen, causing the engine to shake.
- Misfiring Engine
If the fuel injector is unclean, clogged, or does not open properly, the engine will misfire. Misfiring in an engine will stifle acceleration, limit fuel efficiency, and result in power loss.
This needs to be addressed very away, as your engine could start knocking and do catastrophic damage.
- Bad Fuel Odor
This symptom appears when the fuel injector is leaking or not closing properly. Excess fuel emits a foul odor that might be detected while driving.
It could be a leak in the exhaust pipe or an external leak in the engine compartment, both of which are dangerous since they can cause your automobile to catch fire.
- Increases Fuel Consumption
You will notice a drop or increase in fuel efficiency owing to a bad injector if you track your fuel use on a regular basis. A malfunctioning injector distributes either too much or too little gasoline to the engine, lowering the vehicle’s fuel consumption.
It’s possible that a malfunctioning fuel injector is to blame if your fuel usage has altered.
- Rough Engine Idling
It could be a bad fuel injector if you have a rough idle or the engine stalls at low RPM. Because the fuel injector may spray too much or too little fuel, resulting in a lean or rich mixture, the engine may misfire and stall.
- Failed Emission Test
Your automobile will most likely fail the emission test if the spray pattern of the fuel injectors changes, pumping too little or too much gasoline into the engine. This is because either too much or too little gasoline will result in increased emissions, rendering the catalytic converter ineffective.
- Fuel Leak
A faulty fuel injector could be the source of a fuel leak in the engine bay. Fuel injectors are frequently composed of plastic and can shatter, resulting in an exterior leak. If you find a fuel leak in your engine bay, you should replace it right once because it could cause a fire.
Fuel Injector Cleaning
Your fuel injector could be jammed with debris in some circumstances. A faulty fuel filter can cause this by allowing dirt to enter the fuel injector. In this situation, the fuel injector usually has a tiny filter inside it that you can change.
Another scenario is that the fuel injector requires maintenance after being idle for a long time, especially if you’ve been driving on ethanol.
If you wish to undertake injector cleaning, remember that the best approach to avoid varied quantities of fuel spray following the cleaning is to do it all at once.
Some specialized workshops can clean your fuel injectors for you. However, I advocate replacing the fuel injector rather than cleaning it because, in most situations, the problem will return within a year of cleaning it.

- How much does it cost to replace a fuel injector?
The cost of replacing a gasoline injector ranges from $100 to $500, depending on the automobile model and labor charges. A gasoline injector might cost anything from $50 to $300. The cost of labor in a workshop is often between $50 and $200.
Depending on whether you have a gas or diesel engine, the cost of a fuel injector can vary significantly. Diesel injectors are notoriously expensive, with parts costing upwards of $400.
Diesel injector replacement is frequently more difficult than gas injector replacement, however it can be difficult on some gas engines as well.
What should be the fuel injector replacement interval?
Your car’s fuel injectors will normally last 50,000 to 100,000 miles. The type of gasoline used in the car and how frequently the various fuel filters are replaced both have a significant impact on how long the injector lasts. So, if your vehicle is traveling beyond the above limits, then you should change the fuel injector.
