How did your journey home go?

I don't really know what your problem could be. Is it possible that condensed water in the fuel system froze and blocked the fuel flow? Maybe the diesel itself became to thick?

Ya i think thats what happened on the way home it was fine its cold again today but it started fine will see if it happens again
