410B injector pump problem

[jim22]

Fuel injector pump will not throttle up. Starts and idles fine. But if you try to operate hydraulics. Engine will bog down or even stall.

Have you checked for good fuel flow from tank to inj pump?? It's possible the lift pump could be bad.

Yes New pump and filter.

Check fuel return line fitting that screws into pump for blockage. Simple test is loosen screws on timing window on inj pump,pry rubber gasket loose,crank engine to see if that makes a difference.
