When The Fuel Has Run Out (Bleeding The Fuel System) - Mitsubishi FUSO FE 2006 Owner's Manual

4. After the above connections have been com-
pleted, start the engine of the vehicle with the
booster battery and let it run at an RPM slightly
higher than idling speed. Then, attempt to start
the engine of the vehicle with the dead battery.
If the engine starts with difficulty because of cold
weather or a dead battery, let it draw a charge
for several minutes from the vehicle from which
you are receiving the boost before attempting to
turn over the engine.
5. After the engine of the vehicle with the dead bat-
tery has been started, disconnect the booster
cables by reversing the order of connection.
When the vehicle runs out of fuel and the engine
stalls, also when the fuel filter has been replaced, or
if water has been drained from the fuel filter, air that
has entered the fuel system prevents the engine
from being started even if the engine has been refu-
eled after running dry.
In these cases, bleed the fuel system by performing
the following steps.
WARNING
•
A fire could result if there is a fuel leak or if
spilt fuel is not removed. Always wipe off
spilt fuel after air bleeding. Also be sure to
check for fuel leakage.
•
The working space for air-bleeding is tight.
Be careful not to injure yourself on the
edges of nearby parts.
CAUTION
The fuel injection system may fail if the engine
stops due to lack of fuel.
1. Connect a hose
mm (0.31 in.) to one of the air vent plugs
the fuel filter.
NOTE:
•
Use whichever of the two air vent plugs is the
most convenient; both plugs provide the same
effect. Do not use both plugs together.
•
Use a transparent hose so you can easily check
for air bubbles in the drained fuel.
•
If no hose is available, cover the air vent plug
area with a clean cloth and perform air bleeding.
