Ours is working right now. PAB00073. It will rev up and work but if you let it rest it goes to idle like normal. Then it won’t rev up again unless you move the rotary speed dial and then it takes off. We’re ok with that for now but it doesn’t seem to have the digging power it had. We have a manual. Not sure it has all the info we need. At least haven’t located it yet. Want to figure out how to put it in max dig mode or boom priority I’m told. Gonna check the banjo fitting on fuel inlet tomorrow. We changed filters and seem to be getting plenty fuel. I installed a 3/8 clear inline filter and when we changed it out fuel was flowing out it line. HELP hehe. Thanks

    It sounds like a pressure switch is burned out and permanently open. I think there is one or two on top of the valve bank that lets computer know that you operated a function and need to speed up the engine again.

    Could be but even in high engine mode the functions aren’t working as welll as in bypass mode. That’s a bigger issue at the moment
