No start after actuator and fuel shutoff solenoid replaced

[Husky05]

Blew out the line with compressed air. It fired up after cranking for like 10 to 15 seconds I saw the pressure build up, but runs rough and erratic idle. The cel for fuel shutoff solenoid is gone now. Idle would jump from 550rpm to 1000 back and forth. I shut off 4,5,6 injector it stopped idling erratically and ran normal. I have brand new timing and metering actuators on the rear bank. I don't understand what's happening.

So I shut down and tried again, nope no start, fuel rail pressure got up to 32psi that's it.

I now have pid 94 fault that's fuel delivery pressure below normal range.
