Case D40
Hi all, I've been a viewer of this site for a few years but never had a reason to post until now..

My 2006 Case D40 stalled and will not start. It stalled while stopped, trying to switch to a lower gear (it is a shuttle shift)...seemed like the operator had slightly raised off the seat...It would not crank, it is turning over and trying to start, but acting like it is not getting fuel.
So I have checked the safety switch for the seat and the PTO (to be in the un-engaged position). Both switches are ok. I checked all the fuses and the circuit breaker for the starting system. They are all fine.
I began searching/following all the wires around the tractor. I did find a ground wire that was pinched with the rear differential pedal. I have removed the pinch and taped over the bare part of the wire.
It still will not start. Could the fuel shutoff relay have gone bad from the pinched wire?

If anyone has any suggestions of other things I can look at , that would be great!

Thank you!

I would now check the fuel relay and fuse. When you disconnect the relay you should have 12v on 30 and 85 of relay. Check the ground to relay as well. The other wire from relay goes to the fuel solenoid.

Ok. I'll check for voltage at the relay in the morning. Thank you

I am getting 12V's at the fuel shutoff relay. I have replaced the relay but still not getting voltage to the shut off solenoid. Could the Operator Safety Module have shorted or gone bad?
