My john deere gator wont crank with the key switch, I can jump wires at starter and it will fire right up.?

My 6x4 gator wont crank when I turn the key to try crank it does nothing but the fuel pump does come on. I got voltage to key switch and leaving when try to crank but its not making it to the relay. I got a new switch and relay. I checked the diode, my battery is good, I tried a jumper wire on neautral safety switch and also with it unplugged and nothing. Could the cdi prevent it from cranking the starter if it was bad but still allow it to crank and run when I jump it at starter. If i had a wiring diagram it would help. Thanks for your time.
