Running Out of Fuel
If the engine stalls and you think that you’ve run out of
fuel, do this to restart your engine:
{
CAUTION:
Diesel fuel is flammable. It could start a fire if
it gets on hot engine parts. You could be
burned. Do not let too much fuel flow from the
air bleed valve, and wipe up any spilled fuel
with a cloth.
1. If you’re parked on a level surface, add at least
two gallons of fuel. However, if you’re parked on
a slope, you may need to add up to five gallons
of fuel.
2. Follow the fuel priming procedure earlier in this
section to prime the fuel filter.
3. Close the air bleed valve.
4. Turn the ignition key to START for 10 to 15 seconds
at a time until your engine starts. If the engine tries
to run, but does not run smoothly, increase the
rpm a little using the accelerator pedal. This will help
force air through the system.
Fuel Filter Replacement
If you want to change the fuel filter yourself, here’s how
to do it:
{
CAUTION:
Diesel fuel is flammable. It could start a fire if
something ignites it, and you could be burned.
Do not let it get on hot engine parts, and keep
matches or other ignition sources away.
First, drain any water from the filter following the
procedure for draining water listed previously.
Your vehicle’s engine should be off until the end of this
procedure.
The fuel filter is located in the engine compartment on
the passenger’s side of the vehicle, or on the driver’s
side frame rail in front of the fuel tank.
