I am new to turbines and was wondering if cold diesel on a cold day would be a factor, today was 12 degrees C and after a few good starts on the above settings QUOTE]

Yes. temp makes a difference they are harder to light off on colder days . Once lit the fuel ring and injectors are heated to atomize the fuel. You will notice once lit off. it will start consistently unless it cools to ambient temp again.
