hi just after some help i try to start from cold and struggles to fire.Once it has started will start all day long.If i leave for a couple of days it is hard to start.I have changed the glow plugs twice,the first set were cheap ones and i thought that they were at fault.i bought some ngk ones thinking this would solve it but no difference.I was wondering if it could be fuel elated ?.Is it possible for the fuel to drain out of engine over a few days.Any help would be great thanks pete
