DESCRIPTION AND OPERATION
Fuel Charging and Controls
The fuel injection supply manifold (9F792):
zdelivers fuel to the fuel injector.
z receives fuel from the fuel supply line.
The throttle body:
zcontrols air supply to the upper intake manifold by positioning the throttle plate.
z connects the accelerator cable and, if equipped, the speed control actuator cable to the throttle
lever.
z is not adjustable.
z cannot be cleaned.
The fuel injector:
zis electrically operated by the powertrain control module (PCM).
z has an internal solenoid that opens a needle valve to inject fuel into the lower intake manifold.
z atomizes the fuel as the fuel is delivered.
z is deposit- resistant. Do not clean.
The fuel pressure relief valve:
zis used to inspect and relieve fuel pressure. Fuel Charging Wiring Connections SECTION 303-
