How do fuel injectors work?

A fuel injector is an essential component of the fuel delivery system which is responsible for supplying fuel to the engine. Usually vehicles have one fuel injector attached to each of the engine’s cylinders. The injector is directed by the internal computer of your vehicle to pump in the necessary fuel, at a specific angle and at a specific speed.  In a nutshell, a fuel injector controls the fuel that is supplied by the fuel pump into the combustion system of your vehicle.

What causes a Fuel Injector to Fail?

Many reasons could be behind the failure of your fuel injector like carbon build-up or poor quality of fuel. There could also be a ‘heat soak’ happening which means that the fuel that remains after you shut your engine might be evaporating into the fuel injectors which might cause it to work in an improper manner. In addition to that, if you use poor quality of fuel and don't replace the fuel filter every now and then, your vehicle's fuel injector could fail due to a build up of contaminants. 

How to Fix a Bad Fuel Injector

You can fix a bad fuel injector by removing the injectors from the engine and cleaning them. You can either get the injectors cleaned with a professional’s help or you can do it yourself. The point is to unclog the injectors so that they work properly.
