I bought a 2011 800 about a year ago. Worked great till January cold day when I tried to start it and came up with 0637 8 error and now don't start. I've tinkered on it alittle and jumped the fuel pump and it starts right up and runs without any stuttering or any noticeable problems. But will not start without hot wiring the fuel pump and still shows error code

CLT, soooooooo, you step on the brake and nothing happens when you turn the key ??? but you "jump the fuel pump' (just the fuel pump).................and it starts right up ? Is that right ?

I press the brake and it turns over but no start. And I just jump the fuel pump and work for on brake turn key and it starts

CLT, have you swapped relays and checked fuses ?

 

[CLT93]

Checked and swapped yes. Just keeps giving cam sensor code. disconnected battery, to try reset. Replaced cam sensor. I've looked up on Google for related issues. Sounds like common code but no common solutions
