Went riding all day. Then shut down on a lake. When I tried to start it, sounded like it wanted to go, headlights came on a bit, but no dice for pulling it over. Checked sparked. Got spark. Disconnected one fuel line and pull it over. Bit of fuel came out for every pull. Checked the other fuel line and it was steady steam of gas and won't stop until held above the pump. My guess the fuel pump. And the engine is getting flooded??Any other ideas?

only one fuel line on an EFI the other is the return line, It sounds like you TSS has fouled out. That is your throttle safety switch if you unplug it and jump across. Alot of the sleds had a jumper that came with them all you had to do was plug it in. But anyway jump across the plug and this should by pass the TSS and your sled will run. But be aware it also disables the Emergency kill switch.

Sweet. Thanks man. That was my first though. But I though it wouldn't allow spark. Then the fuel lines through me through a loop. So is it just the two wires leading to the emergency switch to splice together. Might have to do some research to property jump this sensor.

a faulty tss might allow spark only intermittently at best, not enough to run at idle rpm.

yep just by pass the wires from the kill switch that is also from the throttle control. It is a three wire plug but one of the wires is only a ground so put a jumperwire in the male to female connectors and it should fire right up. I have been running my sled like this for two years.
