Have an MU500, I believe it is a 2014.  It just started not wanting to start, so I changed the battery since it was about time to need a new one.  Now it starts without any problem, but will shut off in an idle.  If I give it throttle it will keep running, though it does sound a little rough, but once it gets to idle speed it shuts off again.  The only way to keep it running is to keep the gas pressed.  Any idea what might be causing this?

Digital dash? Codes? Check engine light?

Kinda same issue on 2021 axis 500. Wouldn't idle on its own, only happened that one ride so far. Had code 201 flash on dash. Called tech and he said to change filter and spark plug. Haven't done it yet. Kinda busy.

1. Check injector wiring.

2 Check all wiring.

3. Check ail filter. Could be choking itself out at idle.

      Travel time question
      By Greg Kilgore
      I would really like to know what you guys think about this. I'll try not to ramble and make it as clear as I can.
       
      I took this new job with companyX as a fiber splicer a year ago. I have a 45' bucket truck and 10or12 x 8 ft enclosed splice trailer I have to take home. Within the last 6 months all the management in the splice dept left. Now the power/construction management and higher ups are filling in. Just recently we were told travel to our 1st job is not payable even though we are in a company vehicle. 
      We are union so I asked the union business manager about this. His reply was be grateful you were paid travel as long as you were and that you don't have to drive your POV to the job.
       
      Last week I had 50hr total. The job area is 4-4.5 hrs away. My time was reduced to 44.5 hrs since we were told this travel thing on Tuesday of that week. I wasn't hired for this area. I was hired for area a lot closer to home. 
       
      Pay is good. Work is not hard. Insurance is through the union and so far pretty good.
      But I hate the thought of having to work extra just to make a 40hr paycheck. Anyone who has to drive as part of their job knows windshield time is not easy.
       
      Anyway what do you guys think. Should I look for a different job or just suck it up because of the decent pay and health insurance.

      Bit of background. First the machine would take for ever to start. So I adjusted the valve shims into spec and made sure the timing is correct. Starts perfectly now. 
       
      now it fluctuates on idle. Bogs down, Revs up, repeat. I noticed the fuel pressure drops from 60psi to 20psi while that happens. It also bogs down at the lower end of each gear, higher rpm seems to be fine. Seems to struggle under load. In neutral it revs up perfectly. 
       
      brand new fuel pump, fuel filter, gas. I noticed on the fuel pressure regulator there’s that vacuum nipple, it’s not attached to anything and I’m not sure where it would go. Possibly the problem? 
       
      Another issue is the tip off the end of the exhaust is broken off, sensor is still attached and connected. Could that cause these issues? 
       
      my next plan was to look into the pressure regulator and voltage to fuel pump while driving. Is there anything I’m missing or any ideas you guys have? 
       
      thanks!

      Hello All...
           Just bought a 2014 Massimo 500 UTV.  It;s not running at the moment, but hopefully will soon.  I need a seat for it also (passenger side, if it makes any difference.)  It is a crank-but no start situation.  Just now starting to read the boards for solutions.  Apparently these models are well known for this issue.  If anyone has any suggestions, please feel free to chime in, it would be greatly appreciated.
      Thanks

      New member From Northern Indiana . and coolant ??????
      By Tarak1980
      I have a Coleman HS400UTV-5 got it manly for hunting and spending time with the grandkids
      The one problem I am trying to avoid. My son borrowed it last summer and said it ran hot so he added water to it . I do not know how much he put in so I would like to drain most of it and add new coolant to protect it this winter. I can find no drain cock or any way of draining it besides loosening a hose.  Any suggestions ????

      Coleman UT400 - 6v or 12v battery?
      By Rainman
      I want to put a charger/maintainer for my Coleman UT400 for the winter and need to know if it uses a 6v or 12v battery.
      One search online showed a 6v, but another stated 12v..
      I can look at the battery, but after taking the seat out you cannot see the top of the battery without also removing the top plate under the seat and at 8 degrees outside, I'd rather not be out there too long.
      Can anyone verify what volt (6 or 12) the batter is?
      Thanks in advance ...
