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.
1. Add a substantial amount of fuel to the tank,
approximately 2 to 5 gal (8L to 19L).
2. 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.
3. Start the engine using the Normal Starting proce-
dure page 126.
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 die-
sel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gasoline, the
use of these fuels can cause damage to the fuel sys-
tem. Do not start the engine as damage will occur
that is not covered by the New Vehicle Limited
Warranty.
NOTE:
•
In addition, commercially available fuel additives are
not necessary for the proper operation of your diesel
engine.
•
For extreme cold conditions, "Mopar® Premium Die-
sel Fuel Treatment" is recommended to assist with
cold starting.
