I have a 2010 prowler 1000 xtz, it will not start. I have checked the timing, made sure the valves were adjusted right, replaced the spark plugs, fuel pump twice, inline filter, and injectors. It still seems like it's not getting fuel. I know there is fuel going through the injectors, but still will not start. I poured a little gas in the throttle body, and it will run until the gas is out. Any suggestions?
