-----Answer-----
if its getting that cold that the fuel i freezing, you need to get rid of the moisture in your gas and tank. add some dry gas to your tank. it absorbs the moisture in your tank, and passes it thru the fuel system. after that, if you have a problem with a no start, check fuel pressure, make sure you have spark, and check your air flow. those are the three things needed for an engine to run.
Answerok, did you put the dry gas in? if you did, and the fuel is frozen in the line, youll have to thaw it out. at least where the fuel feeds into the injector rail. try taking a hair dryer and heating the fuel rail up. also, once your sure the fuel is flowing, check the fuel pressure. you might have a weak pump.
