check engine light FORD E SERIES 1999 4.G 7.3L Diesel Supplement Manual

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.

A symbol has been developed by the
American Petroleum Institute (API)
to help you select the proper engine
oil. It will be included on the oil
container you purchase. The top
section of the symbol shows the oil
performance by the API designation.
This should match the owner guide recommendation. The center section
will show the SAE viscosity grade. The lower section will state energy
conserving if the oil has proven fuel saving capabilities.
Changing engine oil and filter
Change your oil and filter according to the ªService Guideº. Change more
frequently if your vehicle operation includes extended periods of idling
or low-speed operation, driving for a long time in cold temperatures or
driving short distances. See the following section ªEngine Lubrication for
Severe Service Operationº for all severe duty restrictions.
Use Ford Engine Oil Filter Part No. F4TZ-6731±A (FL±1995) or
equivalent. These filters protect your engine by filtering harmful,
abrasive or sludge particles. The FL±1995 filters particles significantly
smaller than most available ªwill fitº filters.
To replace, use an oil filter wrench to unscrew the filter from the oil
cooler fitting. Turn it horizontally to let excess oil drain off, and remove.
Do not handle a hot oil filter with bare hands.
Clean the filter mounting area on the oil cooler, lightly coat the gasket
surface of the new filter with clean engine oil and hand tighten until the
gasket contacts the base.Then tighten another 1±1/4 to 2 turns.Fill
the crankcase and run the engine to check for leaks.
Continuous contact with USED motor oil has caused cancer in
laboratory mice. Protect your skin by washing with soap and
water.

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 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 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 relay terminals. Also, make
sure the relay bracket is securely fastened to its mounting surface.
If the starter relay clicks, but the starter does not crank, check the
connections at the starter terminal. If a discharged battery is suspected,
have it checked and corrected.
²For vehicles with manual transmissions, the clutch pedalmustbe fully
depressed in order for the starter to operate.
²For vehicles with automatic transmissions, the gearshift lever must be
in Park or Neutral in order for the starter to operate.
²Try 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.
²If all electrical connections are tight and you need assistance to start,
see ªJump Starting Your Vehicleº in theStartingchapter.
IF ENGINE CRANKS BUT WON'T START
Prolonged starter cranking (in excess of 30 seconds) could cause
damage to the starter motor.
²Check 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
tank control switch is set for the tank with fuel and not on an empty
tank.
²Leaving the ignition key 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 OFF and then back to
ON again.
