FUELING
WARNING:
Do not use starting fluid such as ether or gasoline
in the diesel air intake system. Such fluids can cause immediate
explosive damage to the engine and possible personal injury.
If you fuel your vehicle at a truck stop, you may notice that the fuel
nozzle may shut off every 5–10 seconds. This is due to the flow rates
being designed for larger heavy duty trucks. You may have to fuel at a
slower rate (don’t depress the nozzle trigger fully).
Do not run your diesel vehicle out of fuel as this will allow air to enter
the fuel system which will make restarting difficult. The engine is
designed to run roughly as the fuel tank nears Empty. This is a warning
to the driver to add fuel as soon as possible. Longer engine cranking
time may be required once air is in the fuel system. If air enters the fuel
system (either through running the fuel tank(s) empty or during a fuel
filter change), the engine will self-purge the trapped air once it starts
running. The engine may run roughly and produce white smoke while air
is in the fuel system; this is normal and should stop after a short time.
MINOR TROUBLESHOOTING GUIDE
Air purge procedure
Turn the key on for 30 seconds, then turn off. Repeat procedure four or
five times.
If the engine won’t crank
Turn on the headlights. If the lights are dim, do not go on at all or 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.
