Parked the gator (outside) for a couple months and now it won't start. Fuel injected, gas engine with about 1720 hours. It's getting gas (drained the old and replaced with new, non-ethanol), changed the plugs, changed the fuel filter, getting good blue spark at the tip, getting air, not throwing any codes unless I unplug something. Fuel line is under good pressure. Pistons are moving and it cranks and cranks but won't fire. Put in a new ECU, changed oil, did everything I know of that deals with air, fuel, and spark but it won't fire. this thing has never done this so am at a loss as to what to try next - trying to fix on my own, to take it to a dealer would be defeat!
