2006 FORD SUPER DUTY ignition

The FCM/HFCM should be drained
at regular intervals or when the
WATER IN FUEL light illuminates in
the instrument cluster.
The fuel injectors are located in the center of the combustion chambers
in the cylinder head between the rocker arm assemblies. The glow plug
system and fuel injection system are controlled through the Powertrain
Control Module (PCM) and Fuel Injection Control Module (FICM).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump.
The fuel pump provides pressurized fuel to the engine and is
electronically controlled by the fuel pump PCM relay. The fuel pump
contains a pressure relief valve for overpressure protection in the event
of restricted flow.
Lubrication system
It is important to change the engine oil at the recommended service
intervals, because oil viscosity is important in maintaining the oil
pressure required to actuate the fuel injectors. Extended oil change
intervals can negatively affect engine performance, fuel economy and
engine life. Refer to the engine oil specification chart located under
Engine oil specificationsin theMaintenance and Specifications
chapter of this supplement.
Fast start glow plug system
The glow plug system consists of:
•eight glow plugs
•the glow plug control module (GPCM)
•engine oil temperature (EOT) sensor
•barometric pressure (BARO) sensor
The glow plug system is
electronically controlled by the
PCM. The GPCM energizes the glow
plugs immediately after the ignition
is placed in the ON position, then determines how long the glow plugs
will be on according to the EOT and BARO sensors. The required time
for the glow plugs to be energized decreases as the engine oil
temperature and barometric pressure increase.

Glow plug pre-heat indicator
With the key in the ON position,
the
light will illuminate if
glow plug heat is necessary as a
starting aid. Wait until the light goes
off before starting. The light should always illuminate briefly, when the
ignition key is in the ON position. If the light does not illuminate, there
may be a problem. Refer toCold weather startingin theDriving
chapter of this supplement. After the engine starts, the light should
remain off. The light should always illuminate at least momentarily when
the engine is cold and the ignition is turned to ON. If it does not
illuminate, the glow plug system should be checked and repaired
promptly to avoid difficulty in cold starting.
Waterinfuel
During refueling, it is possible for water-contaminated diesel fuel to be
pumped into your tank. Your vehicle fuel system is equipped with a fuel
filter/water separator to remove water from the fuel. The WATER IN
FUEL light will illuminate when the ignition is turned to START (as part
of the light function check) and when the FCM/HFCM has a significant
quantity of water in it.
Type A
Type B
Type C
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the FCM/HFCM.
Refer toDraining the FCM/HFCM and changing the fuel filtersin the
Maintenance and Specificationschapter of this supplement for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system.

1. Turn the key to 4 (ON) without
turning the key to 5 (START).Do
not start the engineuntil the
glow-plug pre-heat indicator
turns off.
2. When the glow plug pre-heat
indicator turns off, turn the key to 5
(START), then release the key as
soon as the engine starts. The glow
plugs will continue to be activated for two minutes after the glow plug
pre-heat indicator
has turned off. If the engine is not started
before the glow plug activation time ends, the glow plugs will need to be
reset by turning the key to 3 (OFF).
3. After the engine starts, allow it to idle for about 15 seconds. Do not
increase engine speed until the oil pressure gauge indicates normal
pressure.
STOPPING THE ENGINE
Turn the ignition to 3 (OFF). To prolong engine life (after extended high
speed or maximum GVW operation), it is recommended that a hot engine
be allowed to operate at low idle for about 7–10 minutes which would
allow sufficient time for the turbocharged engine to cool down.
COLD WEATHER OPERATION
Changing to a lighter grade engine oil also makes starting easier under
these conditions. Refer toEngine oil specificationsin theMaintenance
and Specificationschapter of this supplement.
At temperatures below 20°F (–7°C), Number 2–D diesel fuel may thicken
enough to clog the fuel filter. Your vehicle is equipped with either an
FCM (E-Series) or an HFCM (F-Super Duty) which acts as a fuel
filter/heater/water separator to keep the wax melted which will help
prevent fuel filter clogging. However, if the engine starts but stalls after a
short time and will not restart, the fuel filter(s) may be clogged. For best
results in cold weather, use Number 1–D diesel fuel or “winterized”
Number 2–D diesel fuel which has an additive to minimize wax
formation.

If you fuel your vehicle at a truck stop, you may notice that the fuel
nozzle may shut off every 5–10 seconds. This is due to the flow rates
being designed for larger heavy duty trucks. You may have to fuel at a
slower rate (don’t depress the nozzle trigger fully).
Do not run your diesel vehicle out of fuel as this will allow air to enter
the fuel system which will make restarting difficult. Longer engine
cranking time may be required once air is in the fuel system. If air enters
the fuel system (either through running the fuel tank(s) empty or during
a fuel filter change), the engine will self-purge the trapped air once it
starts running. The engine may run roughly and produce white smoke
while air is in the fuel system; this is normal and should stop after a
short time.
MINOR TROUBLESHOOTING GUIDE
If the engine won’t crank
Turn on the headlights. If the lights are dim, do not go on at all or if
when the ignition is turned to 5 (START) the lights become dim or go
out, the battery connections may be loose or corroded, or the battery
may be discharged. If there is a clicking or stuttering sound coming from
the engine compartment when you turn the key to 5 (START), this may
also indicate a loose or corroded battery connection.
Check the battery connections at the battery posts, cable connection to
the engine grounding point and at the starter connection.
If a discharged battery is suspected, have it checked and corrected.
Battery posts, terminals and related accessories contain lead and
lead compounds.Wash hands after handling.
•For vehicles with manual transmissions,the clutch pedalmustbe
fully depressed in order for the starter to operate.
•For vehicles with automatic transmissions,the gearshift lever
must be in P (Park) or N (Neutral) in order for the starter to operate.
•Try operating the starter switch several times. Should the switch be
corroded, this operation may clean the contacts or make the switch
temporarily operable until you can reach the dealer.
•If all electrical connections are tight and you need assistance to start,
refer toJump startingin theRoadside Emergencieschapter of your
Owner’s Guide(F-Super Duty ) or refer to theJump starting
section in theRoadside Emergencieschapter of this supplement
(E-Series).

If engine cranks but won’t start
Prolonged starter cranking (in excess of 30 seconds) could cause
damage to the starter motor.
•Check the fuel gauge. You may be out of fuel. If the gauge shows that
there is fuel in the tank, the trouble may be in the electrical system or
the fuel system. If equipped with an auxiliary tank, be sure that the tankcontrol switch is set for the tank with fuel and not on an empty tank.
•Leaving the ignition key turned to 4 (ON) for over two minutes
without starting may make starting difficult because the glow plugs
will cease activation. Reset the system by turning the ignition key to 3
(OFF) and then back to 4 (ON) again.
If the engine runs hot
The following could cause the engine to overheat:
•Lack of coolant.
•Dirty cooling system.
•Plugged radiator fins, charge air cooler, A/C condenser and/or oil
cooler.
•Driving with frozen coolant.
•Sticking thermostat.
•Overloading or pulling heavy trailers during hot weather.
•Grill or radiator air blockage.
•Slipping or missing drive belt.
•Plugged or very dirty air cleaner element.
If fuses burn out
Burned-out or blown fuses usually indicate an electrical short-circuit,
although a fuse may occasionally burn out from vibration. Insert a second
fuse. If this fuse immediately burns out and you cannot locate the cause,
return your vehicle to your dealer for a circuit check.
Replacement fuses and circuit breakers must always be the same
rating as the original equipment shown. Never replace a fuse or
circuit breaker with one of a higher rating. Higher rated fuses or circuit
breakers could allow circuit overloading in the event of a circuit malfunction,
resulting in severe vehicle damage or personal injury due to fire.
Refer to theOwner’s Guidefor replacement of fuses.
