Hi, new member here, thanks for the ad. Our 2012 hisun hs 500 utv turns over but won't start unless primed. It'll run then for a few seconds & shut back down. It's just not getting fuel. Things we've done, installed brand new fuel pump, fuel pump relay, starter selonoid, replaced all the small fuses in fuse container...10-15 & 3 amps. Replaced a few Butt Connectors a 30 amp. Fuse for headlights. Tapped up some electrical wiring. Nothing has helped. It always started instantly. At a loss as to what to do next. Any suggestions would be so appreciated. TIA. Ann
