How’s it going gents, I have a komatsu pc228, the motor will not start. Acting like it’s under full load from the pump, I have code E306, the feedback potential circuit is abnormal, we tested the solenoids and we’re getting the in between 40-60 ohms of resistance the book requires and they were all good. The other code it was originally throwing was for throttle pump control valve. I replaced it and still can’t get her to fire. Any help would be appreciated. Thanks

Update, all original codes have been cleared, by diagnosing a bad pump controller, I now have only one, e234, but the pump is still loaded up and engine will not crank. Thanks
