Need help!

While operating my D530TC backhoe it started to lose power and then just shut down. Now it will not start. Plenty of fuel and oil. Any suggestions? Thank you in advance.

Does inj pump have an electric fuel control solenoid? If so is it operating correctly? What type fuel system inj pump or other type?

If it lost power slowly. Then that could indicate a clogged fuel filter or collapsing line. Change fuel filter first.

It has new fuel filters but I will pull them out and check their condition. Thank you.

I am not sure if it does or not. I will go check. It has the A35774 Fuel Injection Pump according to the parts manual.

The parts manual doesn't show an electric fuel control solenoid.

Nothing electrical anywhere near the fuel control. Fuel filters look good with plenty of fuel and no trash. Although the fuel line needs replacing, it isn't visibly collapsed anywhere.

I hope I am doing this right. I am attaching a copy of the fuel system diagram.

No diagram. Ok new filters. Steel lines don't collapse they plug. But any rubber lines can collapse. Check the condition of all lines. Check and make sure tank isn't plugged. Start at tank and see where full stops flowing. That's your problem.

Any lift pumps that can go bad?

Sorry about the diagram. Have good fuel flow all the way from the diesel tank thru the filters and into the fuel control. No lift pump or any kind of pumps that can go bad.
