When the fuel has run out
(Bleeding the fuel system)
When the vehicle runs out of fuel and the engine
stalls, when the fuel filter element has been
replaced, or when the water in the fuel filter has
drained, air that has entered the fuel system pre-
vents the engine from being started even after the
engine is refueled.
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.
CAUTION
The fuel injection system may fail if the engine
stops due to lack of fuel.

Alternatively, connect a hose with an inside diame-
ter of 8 mm (0.31 in.) to the pipe portion of the air
bleeder plug in order to prevent fuel from splashing.
Use a transparent hose so you can easily check for
air bubbles in the fuel.
3. Fuel containing air bubbles will flow out of the
pipe portion. Continue pumping until the fuel no
longer contains any air bubbles. (You will need
to operate the priming pump approximately 60
to 80 times.)
