If gas came out then you have issues

What do you mean froze up?

Well I plugged in the block heater for an hour and it started so I'm guessing there may have been some water in the gas? Idk

Lol, every time you say gas, someone is gonna say something about it. Try 'fuel' -an extra letter to type, but works much better

Mine sits for many days at a time and never a problem up in North Dakota. The worst time was about 8 days without running, pointing front first into the cold north winds, air temp -20 to -30F with windchill running -50 to -55F. Unbelievably cold but she started up first crank. I should have plugged it in but it was too cold to mess with and I wanted to see how it started. It was loud and didn't like it but after 30 sec it idled up and was just fine. This is on a 2012 LML, I use optilube as well so the fuel doesnt freeze up.

Plug it in if you want it to warm up quicker otherwise dont worry about it, it will start. Doesn't get much worse than what mine has went through.
