Cold Weather Starting Problem

95 continental usually won't start after cold night/morning.
starts fine on warmer days.
engine turns over fast as usual, just won't start until outside temperature rises.
Could it be moisture in the fuel lines freezing and blocking fuel flow?

Thats how my 95 cont. is or may be also, it worked up until it started snowing and now it wont turn over but I have yet to see a warm day to try and start it on.
