2004 F350 6.0. Traveling 600 miles after purchasing the truck it overheated due to a lack of antifreeze. It did an automatic shutdown. Hours later after it cooled it turned over and ran for about 1 minute. I changed the oil and all filters but now it will not start. It turns over normally but acts as if its not getting any fuel. I've checked and fuel is at the filter and flowing through it with normal pressure. It still won't start!! It turns over normally but will not fire even with ether. What do I check next or must I open it and look further?
