Fuel injector function
Fuel injectors are a crucial component of modern engines, playing a significant role in both performance and emissions control. They are responsible for delivering precise amounts of atomized fuel into the engine's combustion chamber, optimizing power and minimizing fuel consumption.
The primary function of a fuel injector is to regulate the injection of fuel into the engine's combustion chamber. This is achieved through atomization, a process that breaks down the fuel into fine droplets, creating a mist that can be easily mixed with air. This atomized fuel is then sprayed or injected directly into the combustion chamber, where it is ignited to generate power. The injector ensures that the correct volume of fuel is delivered, optimizing the air-fuel mixture and resulting in efficient combustion.
Fuel injectors consist of several key components, including a solenoid (an electromagnet), a nozzle, and a needle within the injector body. The solenoid, controlled by the powertrain control module (PCM) or the electronic control module (ECM), plays a crucial role in regulating the fuel injection process. It receives an electrical signal, which causes the injector needle to lift, allowing high-pressure fuel to flow through the nozzle and into the combustion chamber.
The PCM or ECM controls the solenoid's "on" time, adjusting the duration of fuel spraying to match the engine's needs. For instance, during heavy acceleration, the fuel injector will spray for a longer duration compared to when the engine is idling. This precise control ensures that the engine receives the optimal amount of fuel, improving performance and fuel efficiency.
Additionally, fuel injectors play a significant role in emissions control. By optimizing the air-fuel mixture and ensuring efficient combustion, fuel injectors help reduce carbon and greenhouse gas emissions. Modern fuel injectors, with their advanced technology, contribute to meeting stricter emissions standards, making them an essential component in the transition from fossil fuels to cleaner energy sources.

- Off-the-Car Cleaning: For a more thorough cleaning, it is recommended to remove the fuel injectors from the vehicle's engine. This allows for the removal of internal gunk and the replacement of tiny internal filter baskets within the injectors. This method requires specialized cleaning and test equipment and is best performed by a professional technician.
- On-the-Car Cleaning: In some cases, you may be able to clean the fuel injectors without removing them from the engine. This involves running the engine with a pressurized canister of cleaner and fuel attached to the fuel rail. However, this method may not be as effective in removing internal clogs.
Fuel Injector Replacement:
In some cases, fuel injectors may be beyond repair and require replacement. This is typically recommended when the injectors are severely damaged or when cleaning does not resolve the issue. Replacing fuel injectors can be a complex process and should only be performed by a qualified technician. It involves draining the coolant and oil, removing engine components, disconnecting the fuel injectors from the fuel rail and electrical connectors, and installing new injectors.
Precautions:
When working with fuel injectors, it is essential to take the necessary precautions to ensure your safety and avoid potential hazards. Always disconnect the battery when working with fuel, and be cautious to prevent fires, especially when dealing with leaking fuel injectors.

Fuel injector removal
Fuel injectors regulate the amount of pressurised fuel used for each engine cycle. When a fuel injector fails or clogs, engine power is reduced and misfires will occur. The check engine light will turn on and, as the issue progresses, the engine may stall immediately after starting, fail to start, hesitate under throttle, or vibrate roughly.
If you notice any fuel odour around your car, a leaking fuel injector could be the cause. There should be no external leaks from a fuel injector. If an externally leaking injector is suspected, do not start your car due to the fire hazard.
Fuel injectors should be serviced or replaced by a professional due to the risk of fire and the complexity of the repair. The battery should always be disconnected, and proper precautions taken against fire.
The process for removing a fuel injector from a Chevrolet Traverse is as follows:
- Once the engine is cold, the pressure within the fuel rail is relieved by briefly running the engine with the fuel pump fuse out.
- The upper plenum on the intake manifold is removed, along with any cables, hoses, or wiring that restricts access.
- The supply and return lines are removed from the fuel rail.
- The electrical connectors to each fuel injector are unlocked and removed.
- The fuel rail is then unbolted and removed from the intake manifold.
- The injector(s) requiring replacement are removed from the fuel rail, taking care to not allow any debris to enter the exposed openings.
- An O-ring seal usually holds the injector very firmly in a finely polished bore in the fuel rail.
- Using a new O-ring, the serviced or replaced injector is re-inserted into the fuel rail — using engine oil on the O-ring to prevent damaging it.
- The fuel rail is re-installed, and the supply and return lines are re-connected.
- The plenum is re-installed along with all cables, hoses, or wiring.
- Finally, the engine is run, and a careful check for leaks is performed before the vehicle is road-tested.
The average cost for a Chevrolet Traverse Fuel Injector replacement is between $905 and $1,081, but prices can vary from car to car, with some estimates reaching $1410.
