How to Restart an Engine Out of Fuel
Restarting an engine that has run out of fuel includes the use of special tools to
prime the fuel system. Authorized Detroit™ service outlets are properly equipped
for this type of service. Never use the starting motor and fuel pump to prime the
fuel system. Prolonged use of the starting motor and fuel pump to prime the fuel
system can result in damage to the starter, fuel pump, and injectors.
Use the following procedure to prime the fuel system:
1. Fill the fuel tank with the recommended grade of fuel; Refer to section
"How to Select Fuel". If only partial filling is possible, add a minimum of
10% of the total tank volume of fuel to the tank. If a vehicle is on uneven
ground, more fuel may be required.
2. Prime the fuel system by connecting one of the following approved external
priming pumps to the priming port on the fuel filter module:
• DAVCO Shop Pro FXP 95
• ESOC® 250E or
• ESOC® 455
Table 7.
In an emergency situation the engine-mounted hand primer can be used to
prime the fuel system by operating the engine-mounted hand primer for three
minutes or 250 strokes.
3. Turn ON the ignition (key ON, engine OFF).
4. Wait for the engine system indicators on the instrument panel to go out.
WARNING: PERSONAL INJURY
Diesel engine exhaust and some of its constituents are known to
the State of California to cause cancer, birth defects, and other
reproductive harm.
• Always start and operate an engine in a well ventilated area.
• If operating an engine in an enclosed area, vent the exhaust to
the outside.
• Do not modify or tamper with the exhaust system or emission
control system.
WARNING: PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the
vehicle is parked on a level surface, parking brake is set, and the
wheels are blocked.
