1999 FORD E SERIES stop start

WAIT TO START
With the key in the ON position, the
WAIT TO START 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 to the
Startingchapter in this guide. 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.
WATER IN FUEL
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 fuel filter/water separator has a significant quantity of water in
it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the filter bowl.
Refer to theGeneral maintenancechapter for drain procedure.
Allowing water to stay in the system could result in extensive damage to,
or failure of, the fuel injection system.
Do not drain the water separator while the engine is running.
Fuel may ignite if the separator is drained while the engine is
running or the vehicle is moving.

5. 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 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.
At temperatures below ±7ÉC (20ÉF), Number 2±D diesel fuel may thicken
enough to clog the fuel filter. Your engine is equipped with 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 may be clogged. For best
results in cold weather, use Number 1±D diesel fuel or ªwinterizedº
Number 2±D diesel fuel which has an additive to minimize wax
formation.
Your vehicle is also equipped with a bypass relief valve, located on the
in-tank fuel sending unit, which provides fuel flow to the engine if the
fuel pickup should become plugged by ice or wax. To allow this bypass
valve to function and avoid engine fuel starvation, it is recommended
that, during cold weather operation 0ÉC (32ÉF) or below, the fuel level in
your tank should not be allowed to drop below 1/4 full. This will help
prevent air from entering the fuel system and stalling the engine.
An auxiliary PCM can be purchased through your Ford dealer which, in
conjunction with your vehicle's control software, allows the engine to run
at an increased idle speed for improving cab heat.
Operation in snow
Vehicle operation in heavy snowfall or in dry loose snow that may swirl
around the front of the vehicle may feed excessive amounts of snow into
the air intake system. This could plug the air cleaner with snow and
cause the engine to stall.
Starting

The complexity of the diesel engine makes it so the owner is discouraged
from attempting to perform maintenance other than the services
described in this supplement.
If you experience difficult starting, rough idling, excessive exhaust
smoke, a decrease in engine performance or excess fuel consumption,
perform the following checks:
²a plugged air inlet system.
²water in the fuel filter/water separator.
²a clogged fuel filter.
²contaminated fuel.
²air in the fuel system, due to loose connections.
²an open or pinched sensor hose.
²low engine oil level.
If these checks do not help you correct the engine performance problem
you are experiencing, consult an authorized dealer.
FUELING
Do not use starting fluid such as ether or gasoline in the diesel
air intake system. Such fluids can cause immediate explosive
damage to the engine and possible personal injury.
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.
