Fuel Injector

The fuel injector is a nozzle-and-valve assembly that sprays a precise amount of fuel from the pressurized fuel system into the engine to aid in the combustion process.

Symptoms of a Bad or Failing Fuel Injector

  • Engine misfire
  • Engine hesitation
  • Check Engine Light may come on
  • Fuel leak

Fuel Injector Related Repair Advice

  • Using lower quality gasoline can result in recurring fuel injector problems, even after a fuel injector replacement
  • Fuel injector seals should always be replaced along with fuel injectors
  • Many newer vehicles are using higher pressure fuel injectors that inject fuel directly into the combustion chamber (direct injection), which improves emissions and fuel economy. Older systems inject the fuel into the intake manifold.

Fuel pump is located INSIDE the fuel tank. It's accessed through the top of the fuel tank. The fuel tank must be removed to access the fuel pump.
