I have a John Deere F935 Front End mower, I bought it used. I could start it when I bought it, but ran very rough. I cleaned the fuel tanks and replaced the internal fuel lines. When I had the tanks off I water pressure sprayed the mower to clean it. After replacing the internal fuel lines and putting the tanks back on, bleeding the fuel lines. I started the mower, drove it ~200 feet and it died, and now I cannot start the mower. The battery is good, when I turn the key I hear the fuel pump pumping and lights come on like normal, but nothing else - no click on the starter or anything else. I am perplexed, could it be the Part Number AM102890, Time Delay Module (TDM)? With the key in the on switch (fuel pump clicking) - I did an electric light checked the power coming into the TDM box (I have light on the hot wire), but no light on any of the three out goings wires. Suggestions?
 
Make sure that the deck is not engaged. Sometimes there is a safety feature that will prevent the engine from starting when deck is engaged.
 
Just another thought. JD and Kubota engines with a Denzo ?sp starter will do what you are saying. Not sure if that model is one. You buy an improvement starter
solinoid wiring kit from JD. It provides 12v from the battery without going through the key switch.
 
Ok,the starter will not work if the pedals are not in neutral,there is a safety switch under the steering wheel that hits the parking brake lever,and of course the seat switch. Take your test light and check for power at the starter solenoid,I think it is the purple wire that must be hot when you turn the key. I am going by what I know about the 932 and all of this should be the same. I would crack the fuel line into the pump to check for air(just turn the key on and let it pump.)
 
lebac, I have a PDF of the Deere manual for your 935, if wanted shoot me your email (mine is open)
