With Automatic Transmission

Ignition Wiring Diagram:

OPERATION:
The fuel injectors are solenoid activated, controlled by the PCM. The PCM turns "ON" the solenoids, which lifts a normally closed ball off a seat. Fuel, under pressure, is injected in a conical spray pattern at the walls of the throttle body bore above the throttle valve.
The fuel that is not used by the injectors passes through the pressure regulator before being returned to the fuel tank.
