Frozen fuel lines, is a bit of a stretch, the higher fuel pressure pretty much alleviates any issues, unlike carbs with only suction drawing the fuel up the lines. Just in case their could be some moisture in the line you can try some gas line antifreeze just make sure it is fuel injector safe, the old stuff used to eat the o-rings on the fuel injectors etc., on that note a fuel injector clean might also be wise, as they can get gummed up and dirty over the years causing some surging as well.
