Hi all, Got a 04 F250 6.0L Deisel that was being driven home and died on the way, Hauling a tractor made it more fun. When we looked the battery terminal was about shot and loose and I suspect it may have lost contact during the trip. Repaired all that and now it won't start. There are no trouble codes in the computer, it just cranks and cranks, but won't start. I checked the fuel flow and it seems O.K.
Any helpful hints or suggestions?
Thanks everyone.

 

Just had my 05 in the shop. Ran briefly and died not to restart. Ford said it was an oil pressure valve stuck open. It closed after fooling with it. The new valve was an updated part.
