I could let the system warm until the cold pressure system is not a factor. So I waited the perscribed 5-10 minutes for the wur to warm, and tried again, still no dice.
If I understand what you did there I'm afraid it doesn't work that way.

The cold pressure setting will enrich the mixture when cold and leans out as the temperature rises. If the bimetal strip is allowed to warm up while the engine is off the mixture will continue to lean while the engine still needs it to be rich in order to start.
When checking your cold pressure or making changes with the engine off it is best to unplug the WUR so the unit stays cold.
Let it go bone cold and try agin in the morning.
