Cant start during snow.

[sjef200sxTurbo]

My 84 mk1 had some problems starting when it started getting colder but now it started to snow.it doesnt wanna start at al , I have a good spark and 1.9bar fuel preasure. It sometimes seems to want to fire but nevver really does , I haven't been able to drive it al week.
Got new spark plugs , rotor batery fully charged.
I know its hard to tell whitout seeing the car.
But am I the only one here with this problem or are there more silvia s12 drivers that have the same problem?

My 87 never seemd to have this problem.
