My M8 runs great until you shut it off, then you can't get it to start again. I checked spark and have spark. So, I am thinking fuel. This is fuel injected so I checked for fuel coming out of the fuel pump and have none when I try to start it. It was down to 5 degrees when we were riding so I was thinking I had water in the fuel that froze up. I put isopropyl alcohol in and did no good. I am thinking it is the fuel pump and just wanting some clarification. Thanks
