    850i cranks but wont start.

    My Gator will crank but won't start. I turn the key on and I do not hear the fuel pump running. Check power at fuel pump and it is only 2.5 volts. Check all the fuses on driver side under the hood and the 3 blue fuses on the top row only have 2.5 volts across them while the rest all have 12 volts. I changed out that fuse/relay panel and no change, still only 2.5 volts on those fuses. Battery is new and fuel is fresh.
    I inspected all the harnesses and do not see any evidence that rodents dined on the wires.
    I am beginning to believe that my ECU has died, but before I spend $700 on one, I was hoping someone might have a clue as to what else to check or schematic.

    Thanks!

    Check jdparts.deere.com for a schematic, perhaps that will help. Also occasionally OEM Technical Manuals CDís are listed on eBay. I have found these manuals to be invaluable as a Gator Owner.
