Hi all! I have a 2010 Prowler 1000 XTZ EFI that I bought. It had engine issues so I sent it to PSN (Powersportsnation) and they rebuilt it and tested. I installed it and I could not get it to start. It grinds but will not turn over. It sounds like it wants to. I have replaced the spark plugs twice, cleaned the fuel injectors, I do have a spark on both plugs and it is getting gas thru the injectors. I cleaned the throttle body and I did have to adjust the TBS. The battery was 11.9 VDC so I did hookup my battery booster (that had 12.3 VDC) to it and tried but it just will not start. Any suggestions???
