How to Diagnose Sticking Issues in Electronic Fuel Injector Valves

To ensure that your vehicle runs smoothly, you need to know about problems with fuel injector valves. This can have results that are damaging to engine performance when a fuel injector valve is stuck. Symptoms of a sticking valve can include rough idling, excessive fuel consumption, engine misfires, and difficulty starting the vehicle.

You can get rid of sticking problem from fuel injection valves by following a few steps. 

The first step is to inspect the fuel injector valves for any damage or dirt. Then a special tool to do a fuel injector balance test is used. For a category of tests that are designed to ensure all of the fuel injectors are performing as expected or to track down any issues with the components. If you're able to detect any sticking problems, then you may have to perform more tests to discover what is going wrong.

Dirty, debris, and carbon buildup are the most common reason, but there are others why the fuel injector valves stick. 

Over time, these accumulate in the valves and make the valves sticky. Look for these issues: Examine the fuel injector valve for volumetric blockage or heavy buildup. Regular cleaning and maintenance of the fuel injector valve will help prevent sticking issues from occurring.

Fuel injector valves that have sticking problems are tested, then confirmed, using specialized tooling. 

Another way to test is with a fuel injector flow test. This test measures how much fuel every injector is allowing through. It also identifies any sticking issues and reveals which valves might require cleaning or replacement. A fuel pressure gauge can also be used to locate any fuel delivery problems that may result in causing sticking.

To prevent sticking you will need to maintain and clean regularly. 

Being able to prevent dirt and debris from causing sticking issues would be by checking and cleaning the valves regularly. Each time you stop to refuel your vehicle, you should treat your fuel system to high quality fuel and suitable fuel additives to help keep the fuel doser injector valve clean and working well. In conclusion, fuel injector valves maintenance can result in the long life and peak performance of your vehicle's engine.
