unit will initially fire up and run and quit immediately i’ve installed new fuel filters .is unit supposed to start and run by just turning the key and not be in the operator seat. I have restricted the fuel flow back to tank with the same results Engine is4024TT02
Are you out of the seat when trying to start it? Will it stay running if you are in the seat with the seat belt on? If so, is the auxiliary stuck on? Even partially? You can check it through the monitor. Key on, press and hold menu until "diag" appears, press select. Scroll until the word "valve" appears, press select. Does it say "ON" or "OFF"? If off, then either your auxiliary is on, or there is a wiring issue with that circuit.
