Default LLY will not start?

Buddy backed up to Trailor and set at idle for 5min while hooking up. Surged 3 times and died?? Fuel is getting to the motor. Checked ad150 and fuel lines factory fuel filter good pumped and shot fuel to the top hood. Pulled fuel line to 1st injector. Good! Efi check fuel pressure when cranking to be at 5-6k. What am I missing? Bad diesel? Water.... CP3 go out

Did he plug in a connector for the trailer? Check the 5 fuses for the efi system in the box under the hood.

Those codes set when the FICM receives injector firing commands but it is not receiving a crank signal from the crank sensor.

Check the wiring running to the FICM in the usual rub through spots.
