The glow plug is the most important thing. Make sure that you are using the hottest short plug you can find the GENESIS. Starting the truck may be a bit more difficult in weather that cold. So you may have to lean it out a bit... but after the engine is warm you should return to the recommended settings. In about 75 degree temp. The GENESIS engine takes about 2-3 minutes before it reaches optimum temperature. In your case it will obviously take longer. Keep this in mind when driving the truck around. DONT start leaning out the engine to achieve speed before it has warmed up.

Settings:

Top end: 3 1/2 turns out.

Bottom end: 1 1/2 - 2 turns in from flush.
