If you flipped it i'd start with the rollover sensor... they may have come loose and if it did, it won't run for more than a sec or two..

I would start with your relays. If you're getting spark I don't think it's the roll-over sensor as this cuts spark to the engine. Check the ground on your fuel pump first to make sure it didn't come loose. If that's fine, check all your connections going to your pump and all fuses. Relay info can be found in a search on KFX450hq.com.

From what i've experienced and read from others (flipped mine once) if the RO sensor comes off it will start up and stall within a few seconds.. you'll have temporary spark till it kills it.

You have to turn the ignition off and on a couple of times to reset it after you tip it over!! then it should start

when you turn the key on do you hear the fuel pump prime?if not check your pump fuse this is located in a group of harnesses thats wrapped in a rubber boot under you hood remove the rubber boot and youll see i believe two smaller fused harnesses one if for the fan i believe and one is the feul pump theres a spare fuse in each check that to see if its blown!
