Need urgent help, my '05 F-350 won't start. The truck started fine yesterday morning and was allowed to warm-up as usual, but after driving it for about 60 miles, then parking it for several hours, it wouldn't start at all. The truck had battery, and it cranked as if it WANTED to start, but it wouldn't. Anybody know the problem?

 

Hi
How many miles,
My F350 Did the same thing at about 60,000 Km
It was the high pressure oil pump, they had poor seals in them and had to be replaced.
Once the oil pump was repaired I never had a problem again.
