Fuel Injectors

WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The fuel injectors:

are electronically operated by the PCM.
atomize the fuel as the fuel is delivered.
each have an internal solenoid that opens a needle valve, which injects fuel into the intake port in the cylinder head.
are deposit resistant.
