Hi all I have had the car for 6 months now. All was well until now. On some morning the car car will not start. The car will turn over but not fire up after two or more turns of the key nothing. Then after 3 minutes the car fire up no problem......the car runs fine I thought it might be heater plugs but the car will fire up on very cold frozen mornings....some body told me it might be diesel related...fuel sensor?.... Any help on this is issue will be great.......Jason..
