Try checking fuel line from fuel tank thru filters to fuel pump first If there is a leak between these check filters for iceing up or bad fuel lines. If no leaks look at fuel pump to engine block for leaks. Possible leaking pump or injector line leaks. If not there remove top valve cover and see if injector lines are leaking to injectors. Sometimes cold weather does different things to seals. Bad part about diesel is the water effective in cold weather.
