Dear all,
I have this machine with Kubota V3800-TIE4 engine and it would not start.
So far I have replaced supply pump, feed pump, fuel rail, ECU , pulse sensors and engine harness, with no results. If I apply 5volts directly on the pump solenoid it will start and work just fine.
I do not know what could be the problem since this error is about `pump learning` and as far as I know the engine should start anyway.
