Komatsu Excavator PC200-LC6. S/N close to A82500.
Ran fine one day. Wouldn't start the next. You can crank and crank. No smoke. Acts like a bad fuel shutoff solenoid but from what I can tell this engine doesn't have a shutoff, just a throttle motor. Is this correct?
No error codes. I suspected possible animal damage to the wiring since a bunch of the foam inside the engine compartment was recently chewed off but I couldn't find any damaged wires. This has the 4- and 3-wire plugs at the throttle motor. If you unplug these, E05 appears but it disappears when you plug back in the wires.
Fuses are all OK. Obviously I also re-bled the fuel system and there seems to be plenty of fuel supplied to the system.
Any help in diagnosis would be appreciated.
