Fuel Injector: Description and Operation
FUEL INJECTOR
The sequential multiport fuel injection (SFI) fuel injector is a solenoid-operated device controlled by the PCM.
The PCM energizes the solenoid, which opens a valve to allow fuel delivery.
The fuel is injected under pressure in a conical spray pattern at the opening of the intake valve. Excess fuel not used by the injectors passes
through the fuel pressure regulator before being returned to the fuel tank. A fuel injector which is stuck partly open will cause a loss of fuel
pressure after engine shut down, causing long crank times.
