I am working on a friends 2006 crossfire 700 efi. His brother was riding it, shut it off went inside somewhere and came out and the sled wouldn't start. They brought it home and it sat and now I have it trying to get it trying to run again. I have got it narrowed down to no spark. It is getting fuel, I even put fuel down the cylinder just to make sure. I put a spark tester and wasn't getting anything. Tested the plug coil and it was weak so I changed it out with a good one. I have checked wires all over to make sure there wasn't anything rubbing. When you pull it over you don't really get any dash lights to flash. I tested the key and kill switch, also unplugged them to make sure they weren't the reason. I am running out of ideas and don't really want to just throw parts at it. So I figured I would come here and see what ideas all of you guys have. Thanks a lot.
