DESCRIPTION AMD OPERATION
FUEL DELIVERY SYSTEM
This section of the group will cover diesel fuel deliv­
ery components not controlled by the powertrain
control module (PCM). Various components, relays
and switches are operated by the PCM. Refer to the
Fuel Injection System—Diesel Engine sections of this
group for components that are operated by the PCM.
NOTE: Diesel fuel delivery (except for operation of
the intake manifold air heater and manifold air
heater relays) is not directly regulated by the PCM.
The fuel delivery system of the 5.9L turbo-diesel
engine consists of the:
