cranks but wont start

[bob the builder]

My 04 f350 was idling in the driveway and stalled.Now it cranks but wont start,when it should start it jams and I hear the starter spin.Recently replaced high pressure pump,computer,icp,2 injectors,starter,alternator and both batteries.This is my daily driver with +or- 304 000 km.Any input would be helpfull.
