What is the Fuel Injector all about?

Fuel needs to be transferred from the gas tank to the engine where it can burn and provide power to the car. Gas from the tank goes to the engine by passing through the fuel injector. The fuel injector converts the liquid gas to a fine mist (spray) so that it can burn easily.

The number of injectors is the same as the number of cylinders in an engine. (For example, a four cylinder engine will have four fuel injectors.) Gas is delivered from the fuel pump through the fuel rail and is directed to the fuel injectors.

Keep in mind:

Your mechanic will install a new fuel filter (unless the fuel filter is inside the fuel pump) and replace the upper intake manifold gasket if applicable. Both are recommended during this service.

How it's done:

  • Scan the computer system in the car for codes.
  • Visually inspect injectors for any signs of fuel/gas leakage.
  • If accessible, OHM test each injector.
  • Remove and replace the injector if it is bad.
  • Replace the fuel filter it is not inside the fuel pump.
  • Replace the plenum gasket.
  • Inspect for fuel leakage.
  • Clear diagnostic information.
  • Test drive car.

Our recommendation:

You should follow the manufacture maintenance schedule and get the fuel injectors flushed on a regular basis. This keeps the fuel injectors clean and will ensure a good spray pattern into the cylinders.

What common symptoms indicate you may need to replace the Fuel Injector?

  • Check engine light is on.
  • Engine misfires.
  • Poor gas mileage.
  • Fuel leakage.
  • Smell of gas.

How important is this service?

Your fuel injectors transfer gas from the gas tank into the engine cylinders. Gas enters the fuel injectors in a liquid form, and is converted into a mist, which is then sprayed into the cylinder so that it can burn quickly and efficiently. If one of your fuel injectors is damaged, it will not be able to carry out this function, and your vehicle will operate without the power of that cylinder. When one cylinder is not powered, your vehicle will not run smoothly, and may misfire. It will also likely have far worse gas mileage.
