FORD 2013 F-550 v.3 - Manual (Page 127)

Diesel Messages Action / Description
LOW FUEL
PRESSURE If this message appears during a cold start
or during cold operation 32°F (0°C) up to
10 minutes after the initial cold start; monitor
the message center and if it disappears and does
not re-appear after the engine has fully warmed
up, the low fuel pressure message is most likely
caused by waxed or gelled fuel. To prevent this,
use an anti-gel additive. Refer to your diesel
supplement for more information. The customer
warranty may be void from using additives that
do not meet or exceed Ford specifications. If the
low fuel pressure message persistently appears
after re-fueling during the cold start and cold
operation conditions defined previously and then
disappear when the engine has fully warmed up,
consider different fuel sources.
Low Fuel Operation: If the message appears
when the vehicle is warm and during low fuel
tank level operation, i.e. the tank level is at or
very near empty, refuel the vehicle and operate
the vehicle. If the message reappears after
fueling, see below. If the message does not come
back, the low fuel pressure condition was due to
low fuel levels in the fuel tank.
Normal Operation: If the message appears during
normal operation when the vehicle / engine is
fully warm, and fuel level is not low, the fuel
filters must be changed regardless of the
maintenance schedule interval. If replacement
of the fuel filter does not remedy the low fuel
pressure message during normal operation as
defined above, please take the vehicle to your
authorized dealer.
