CUCV won\'t start.....HELP!! I have a 6.2 diesel and it won't start. I've only had it around a month and it's the first diesel I've owned. It's been colder than usual here (5 degrees at night, maybe 30 during the day) for the last week or so. It cranks but it can't seem to turn over completely. Don't have a clue what to do. Hasn't started in a week. HELP PLEASE!!!
