Fuel Injectors

WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

The fuel injectors are electromechanical devices which both meter and atomize fuel delivered to the engine.

The MFI fuel injectors are mounted in the lower intake manifold.
The valve body consists of a solenoid actuated valve assembly; therefore, fuel flow to the engine is regulated only by how long the solenoid is energized.
An electrical signal from the PCM activates the solenoid.
