LOW FUEL PRESSURE (diesel engine only) - 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. 52 2011 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
