Been having starting issues with my xp900,2011. It turns over just fine. I replaced the fuel pump 2 weeks ago and solved my issue. Then the issue returned. My battery is maintained on a trickle charger, is old but voltage is good. I replaced it just in case and no change. I don't hear the fuel pump cycle when I turn on the key, however I believe it may cycle once I turn the key off for a second or two. Any ideas? Also I don't run fuel with ethanol. Rick
