Lots of little factors likely...

The cold starting probably isn't just sludge, although it could be a component. If you were able to get it started with Dry Gas and much difficulty, you might still have some residual water in the filter. (Always try to keep your tank topped up in extremely cold weather.) Also: ambient air temperature is probably several degrees colder than your car, especially in the morning. That engine block had probably settled down to the low of the day and didn;t have a chance to warm up.
We're getting a bit of a thaw, so run another container of Dry gas in there. I'm not sure I'd take an extreme measures like spraying starter fluid in the intake nozzle; although I've heard that some folks do that, it's probably way to risky for a non-carburetted engine.
Once you get it started, you'll definitely need to change to a lower viscosity oil. I think Dean and Brad recommend 0W40 or 30....check the post index to confirm. This will take a bit of strain off the engine when trying to turn over cold, which is when you'll get the most wear. There's a theory that this might also help minimize sludge but I'll definitely defer to the experts on that...
