Jeep Wrangler: VEHICLE MAINTENANCE / Priming If The Engine Has Run Out Of Fuel — Diesel Engine
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure fuel
spray can cause serious injury or death.
- Add a substantial amount of fuel to the
tank, approximately 2 to 5 gal (8L to 19L).
- Push ignition switch twice without your foot
on brake to put vehicle in RUN position. This
will activate the in tank fuel pump for
approximately 30 seconds. Repeat this
process twice.
- Start the engine using the Normal Starting
procedure.
CAUTION!
The starter motor will engage for
approximately 30 seconds at a time. Allow
two minutes between cranking intervals.
NOTE:
The engine may run rough until the air is forced
from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable under
certain conditions and be hazardous or
explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or
gasoline, the use of these fuels can cause
damage to the fuel system.
NOTE:
- Use of biodiesel mixture in excess of 20% can
negatively impact the fuel filter's ability to
separate water from the fuel, resulting in
high pressure fuel system corrosion or
damage.
- In addition, commercially available fuel additives
are not necessary for the proper operation
of your diesel engine.
- For extreme cold conditions, "Mopar®
Premium Diesel Fuel Treatment" is recommended
to assist with cold starting.
NOTE:
Using a fuel filter that does not meet the manufacturer’s
filtration and water separating
requirements can severely impact fuel system
life and reliability...
