Runs on starting fluid(I know) but not on it's own. Fuel rail pressure is 275 and only code that is active is 4283. I replaced doser valve but still active. Disconnected exhaust from turbo and still no run. No smoke whatsoever. What have I missed?

Put a voltmeter on the fuel shutoff solenoid. -- See if it is getting 12 volts to it. If it is not, then check to see that you can communicate with ECM,.. maybe you have a bad fuse or no power to ECM.

If you are getting power to the shutoff solenoid, maybe it is going bad?. -- You can always remove the guts to it, then disconnect the wire to it and see if it fires up after a few tries. Whatever you do though,.. do not try to jump it out with +12 volts. Could short out the ECM circuit.
