In cold weather, the fuel filter may become clogged by wax naturally present in the fuel. To unclog it, move the vehicle to a warm garage area and allow the filter to warm up.
The fuel filter may need to be replaced. See Fuel Filter Replacement (Diesel).
At temperatures belowC (32 F), it is recommended to avoid using biodiesel blends above 5% blend.
This blend may cause fuel filter plugging, system gelling, and freezing that may affect vehicle starting. You may need to turn the ignition on and off a few times before the vehicle will start. Also, idle the vehicle for a couple of minutes before accelerating.
