2003 FORD SUPER DUTY check engine

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 connection.
If a discharged battery is suspected, have it checked and corrected.
•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 Park or 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,
seeJump Startingin theRoadside emergencieschapter of your
owner guide.
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
tank control switch is set for the tank with fuel and not on an empty
tank.
•Leaving 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.

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.
Refer to the“Owner Guide”for replacement of fuses.
