Yesterday I went to start my truck (2015 LML) and it wouldn't start. Overnight low was -21°F and the temp when I went to start it was -3°F. It would crank fine, fire up, run rough for about 2 seconds and shut itself off. I tried this about 10 times. It just would not stay running. I finally plugged it in and let it sit for about 2 hours and it fired right up.

Has anyone else had issues like this? My LBZ started fine when it was -30° out though it didn't sound the greatest for the first minute.

I don't believe it was a fuel issue because it ran for a couple seconds Everytime I tried. No codes thrown.

LMLs seem to start harder, and smoke much more when cold. I think it has to do with compression being lower.
