"I have a 2001 Skeeter 250 zx
"I have a 2001 Skeeter 250 zx with a 225 Yamaha V-Max on the back. The Yamaha is a fuel injected engine I think it says OX66 on the side. I have had it since new and maintain it very well. Before when I would start the engine it would start right up and "idle". Recently I started having trouble with it staying running ( at start up). What I mean is that when I go to crank it over it "catches" and starts but then dies( like its not getting enough gas). I now have to do this starting up several times before it stays on and idles. Once it starts it has a hard time "idling" until it runs for a bit. After that the engine runs fine, although it does hesitate a bit when first engaged. Runs great at top end and slower. Thought it was a fuel problem so I have gone though the tanks twice, thought it was the bulb but the bulb pumps up and hardens as you pump. It does soften up after a while. New fuel filter and plugs, had it serviced as well. Ran fine with new plugs for a day but then went back to the same. Had the O2 sensor cleaned and it helped for about three start ups where the engine started right up and ran fine. Do O2 sensors go bad and can I replace it fairly easy? Could it be a fuel pump problem and if so where is it located, usually? Any help/suggestions appreciated. Sorry for the lengthy post but getting frustrated having to crank the engine over and over before it starts. Dan"
