I own a 2000 f-350 deisel. I started my truck, let it run for @ a minute, drove about 100 feet, checked my mail and while at idle it just died. Now i can't seem to get it started again. I checked the quanity of fuel ( ok ). I drained some out using the "water in fuel" valve located behind the fuel filter... thinking that might be the problem. Did't work. I'm stumped, fuel filter was changed about 5000 miles ago and the truck is very well taken care of. Does any one have any suggestions???
