Fuel, air or ignition, and I would suspect the fuel pump, but it’s virtually brand new (Delphi). I’ll pop the code reader on it later today and see if any set and spend some time on the Outpost looking for similar posts.

Long crank followed by immediate start probably means that the check valve isn't holding pressure. I *believe* that the check valve is built into the pump.
Check valve failure has no impact other than the long crank, so it's not worth buying another pump to fix. You can also buy an external check valve.
