i have an 02 cbr 600 f4i. the problem is the fuel pump doesnt prime unless the bike is up right. when im sitting on the bike it starts right up but if i move just a little to the left the bike turns right off.if i lean it to the right it stays on.i dont know where to look to fix the problem need help.please and thank you

 

that sounds like a loose wire issue. I would check the fuel pump power connections and make sure its solid. very odd problem though

 

Behind the front fairing is a Bank Angle Switch/Relay. It's used to kill the bike if the bike falls over. It may have come loose and is not sitting properly. I'd start there and confirm it's in the proper position.
