My IR 185 with a deere diesel will start and run for 10-20 seconds. Makes good strong air in no-time during this period. Machine only has 2000 hours on it and has had recent fluid/filters. Seems like RPM's drop ever so slowly and it stops. Doesn't matter if the air is open or closed. I checked the lift pump and its making solid pressure. Engine runs beautifully when it fires but then it shuts off. Holding the throttle by hand at a higher RPM does not save it from shutting off. It will still shut off. When I test the wire that goes to the fuel shutoff solenoid it had 12V while running. Seems like it should have more but it does show 12V - should that be showing 14.4V when running and maybe my problem is the alternator?
If you unplug the oil pressure switch on the engine it will not start.
Should I start by shorting out safety switches one by one? I am think I could put the harness wires together on the 2 wire safety switches until maybe one of them appears to the culprit?
