Blackjet

Finished the rebuild on the 3.0. A few set backs as i lost my house to a fire. Not related to the truck electrical we think. Thank god for insurance! The truck runs good. But! lol Having one major problem, maybe someone can help. After it has ran long enough to bring the temp at operating temps, when shut down it will cranks but will not fire. After 15 minutes or so it starts right up. I think its fuel but really dont have a clue. I took it to a guys shop he pulled the codes and said there werent any. Put the probe up the exhaust it pulled good numbers there.
