Hello new to the forum I have a Komatsu GD655 motor greater it will crank but will not start engine serial number 26127554 any help is greatly appreciated
I think you need to provide some more details on when it started and anything you've done prior to or after it won't start. Is it getting air free fuel? Is there any smoke when cranking and what colour? Does it use an electric solenoid on the injection pump to shut the engine off? These are just a few things to consider.
