Hello folks , new here but I hope with all the knowledge available here y’all can help. I have an m9960 low profile tractor that I’m having a problem with, I washed the tractor a week or so ago and now it won’t start, it will turn over but the fuel pump doesn’t run, all other electronics seem to work like they are supposed too. There is a code on display it is eng ng. The book says that is engine communication problem, I’ve checked most connections in wiring harness and haven’t found anything, has anyone else ever had this happen? Thanks in advance.
