Customer Question

We have an older JD 4320 it will run for about 30 seconds and shut off. We have replaced fuel pump and fuel filter. Any suggestions? Could it be the injector pump?

Does it start right back up or what do you have to do to get it running again?

Sorry for delay had a family emergency.There are 3 things that will cause this and since I don't know what year it is I will list them all.First is low coolant sensor or wiring,high coolant temp or wiring,,low oil pressure of wiring.Whatever it is its trying to prevent engine damage so it shuts down engine.I would first check all fluid levels and wiring plugs at sensors,,make sure there is no corrosion or fluid in each plug, if there is fluid sensor failed. The sensor does not have to have fluid in plug to have failed but that is a guaranteed .problem.Again sorry for delay.Questions or problems let me know I'm happy to assist.A rating is required.
