2012 Case 750L will trip a code for High fuel rail pressure and shut off the dozer. What common things could trip this? Bad sensor? Fuel pressure regulator/relief valve stuck? What diagnostic tips do y’all have? Thanks!
Any of the points you mentioned could cause this to happen, also a stuck injector, air in fuel system, software error lots of things. A specific code may help narrow it down. Continuity in the wires from the sensors to ecu.
Have you changed the fuel filters? I had an 850L that was doing the same thing dealer said it was the ECM but they were wrong changed both fuel filter with Case filters and problem went away. Owner had just changed fuel filters with WIX filters.
Check filters and fuel lines make sure there is no air getting into the system also see Coy Lancaster comment.
