Hello, I have a John Deere 310 K backhoe. Really cold here in PA. Machine started and shut off this morning. Saying engine de rated and moderately low fuel pressure on the screen. Change fuel filters and put diesel 911 in the machine. Still saying engine de rated and kind of sucking the fuel filters dry. Any ideas?
Have a try at blowing the fuel line back into the tank with the Fuel cap off. It should be easy to hear it bubbling in the tank, if not line is frozen or blocked. Then blow on tank opening with rag ball over opening, and hose going into a pail. See what happens. Simon C
