I have 2015 msu 500. All of a sudden I'm not getting any fuel. I thought it was the injector. It wasn't pumping through the injector. And building so much pressure that it was blowing the line off. New filter and injector. Same problem. Any ideas?

Sounds like the injector isn't getting 12v power signal to allow fuel through. It should make a clicking noise when power is applied. Either the ECU or wiring going from the ECU to the injector could be bad.

Found a bad fuse going to the ecu. Fixed it right up

      2017 Challenger 500 No power on take off or hills
      By great8redsfan
      Okay folks. I have a low power issue. Been like this for a few years. Place I work at bought 3 and all have lost most of the pulling power.  They gave them away after local shop worked on one for 3 months and it had great power for about 1 month and then crap. They replaced throttle body, fuel injector, spark plug and IAC motor. Seat belt switches have wires cut and left open so no seat belt warning light anymore. It revs to 6k rpm in neutral but when put in gear and take off in low it just doesn’t seem to want to go anymore. Running 93 octane fuel with Stabil.  Any ideas greatly appreciated. I dont have a scan tool but no codes on dash. If held to floor it pops a little and runs almost 5K rpm but if I let off pedal about an inch it smoothed out and revs up to 6k rpm.

      Fuel economy
      By LongSun
      I can not find it on the board, so I'm afraid I'm the only cheapo on the forum.
      What is the fuel economy of the Hisun HS590? (I guess it is the same as the HS550)
      I count in liter per 100 km, but if you use MPG it's okay with me, but please tell if you use the US or UK MPG!

      2010 500 - New Carb- Hesitation
      By Buddee
      Put a new carb on the 500 to replace the leaking OE one.  Machine idles fine and mid and top end runs great.  It tends to have a hesitation right from the start - bottom end.   Thinking it may be the air/fuel screw??  I didn't do anything with the carb out of the box and is it direct replacement for my machine.  Of interest is the manual choke doesn't seem to work very good now.... wonder is it getting too much air?
       
      Any help appreciated!

      trying to finish assembly "new" 2021 Coleman ut 400
      By buckrub
      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL
