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

Welcome to the site. 

Consider testing and diagnosis before throwing parts at it.  Doing that only compounds  the problem and often masks what is actually wrong with it.  Rember the basics of ICEs.  Spark, Compression and Fuel.

Test for spark and compression. Then try firing it up with a dribble of gas into the cylinder to see if it will run for a second or two.   If it does, you've narrowed the problem down to fuel delivery.

I've read that some of these earlier models particularly  Hisuns were shipped without in line fuel filters.   Their fuel injectors are sensitive to poor or dirty fuel so they quit or won't let it run much at if at all. 

Good luck Doctor, hope you diagnose the disease and that whatever it is,  its an easy and cheap cure.

Thanks.  Someone has already hung several new parts on it, to no avail.  That's how I got it.  I can't get it to the shop for another couple of days due to the snow storm, but hopefully by the end of the week.

Welcome, to the board. In in Eastern, KY also. Not any local authorized repair shop around here that I can find. Haven't tried any other place. 

Since it been down for a while. Charge the battery. Then check for spark. Check for any loose wires and connections.

I changed the oem seats in my Axis 500, replaced with seats from a RZR from ebay. I made the seat base and they fit pretty good. I gave 1 of the seats to a guy up the road for spreading some dirt in the driveway. Gave one to my brother to replace a seat on his mower.

Good luck, let us know how it goes.

Thanks.  I need a passenger side seat also.  Been watching Marketplace but nothing yet.  I guess I'll have to bite the bullet and buy a new one.  Won't do that until I get it running.

Hello All...  (2015 MSU 500)

Well, I finally got a chance to start the diagnostic on the machine.  I have found: 1) has spark, 2) has fuel, fuel pump working (and injector is spraying), 3) has compression.  Cranks (at a good speed), but will not start.  Sounds like it wants to start, fires every once in a while, and the use of starting fluid makes no change. 

Not sure if the valve timing is correct.  Does anyone know (or know of a good place to find) how the timing marks should be aligned for TDC ?  There are 2-dimples on the camshaft (opposite of one another), and currently they appear to be in line pointing to the crank at I think what is TDC (i.e. in line with the piston, rod, and crank).  I can't find an inspection window to see any crank timing marks.

Also, I have what I believe to be some fault indicators displaying on the dash info display.  They are as follows:  201, blinks 4 times, 202, blinks 4 times, 352, blinks 5 times, 336, blinks 5 times, and 37, blinks 5 times.  Anyone know where I can find what they may be indicating ?  The ECM looks brand new, and the fuse/relay box was replaced by me (previous owner destroyed it trying to get it open). 

The unit has only 775 miles on it, and 127 hours.  It's in good shape, with what I believe all original tires and equipment (although it's missing a passenger seat).  

 Any thoughts would be appreciated.

Thanks...

Larry

Best thing is to reset the ECU.

With the key in off position. Turn key on then off 5 times within 30 seconds. Make sure the fuel pump kicks on each time. After the 5th on/off cycle. Leave off 1 minute then try to start the machine. That should clear the error codes and reset the ECU . 

Proper procedure to start is turn key to on. Then once the fuel pump shuts off. The proceed to the turn the key to the start position to engage starter.

 

On this site there is a download section section where shop manuals can be searched for. 

 

If the ECU looks new it may have been replaced. It's also possible that it was a bad replacement. I read somewhere or watched a video stating that bad ECU for these machines were being sold on fleebay. Hope that is not the case.

All those codes deal with spark in one way or another. 

To search for manuals click on the 3 bars in top right corner. That will take you to a webpage to search for a repair manual. You'll probably have to remove the fuel tank and the air blower to get access to the tdc inspection port. Directions are in the manual. 

Good luck

      Axis 500 4x4 turns over but no spark
      By D MAYNARD
      I have an Axis 500 4x4 UTV that I was given.  It looks like an almost new machine with 39 hrs on it however it was apparently under water from the hurricane . I have no spark at the plug. I have replaced the plug, the plug wire, & the stator so far. Can anyone advise me of what i need to check and or replace to get this thing running? Any advise would be greatly appreciated. 
                                    Thank You,

      2022 Sector 750 EPS starting issues
      By GunnersTacklebox
      Hi All,
      New here, but bought a 2022 Sector 750 brand new last march (old stock up here in Canada)
      It's a good bike so far, but I have noticed a quirk and was wondering if anyone else has had a similar issue?
       
      The issue I've had is if I leave the utv parked on any incline, not even a major incline, and leave it to sit for a while (day or two) it will not start properly. It will turn over and not fire until I press the gas pedal, when it will run and rev up, but if I let off the gas it will die. It will keep doing this until I either start it in gear and drive it for a bit or leave it in neutral and roll it down the hill to flatter ground. where it will have to sit for a while. 
      If I park it on a decline there is no issue. fuel is not low, it's occurred a couple times now. 
       
      Any thoughts on the cause of this? Dealership just says bring it in and let them take a look, at my expense of course.

      2015 MSU-500 crank - no start
      By Prepper
      I'm working with a 2015 MSU-500.  Basic symptoms are it cranks well, but will not fire.  It has spark, and it has fuel spraying out of the injector (and spraying starting fluid into the throttle body and plug hole makes no difference).  It has compression.  I bought it not running, and no other information was available.  It has 775 miles on it and 127 hours.  It looks to be in very good shape.   Previous owner replaced fuel pump, ECU, coil, plug, and the fuse/relay box that mounts on the firewall, then gave up.
      My questions relate to cam/valve timing, considering the symptoms and diagnostics so far.  My thinking was the woodruff key sheared off and the crank spun, making it out of time.  My question is, by the pictures attached does anyone have an opinion as to the cam/valve timing being correct?  In the crankshaft picture you can see a timing mark visible.  In the camshaft picture I have arrows directed towards what I think are timing marks (which appear to be exactly 180 degrees from one another).  However, the long arrow in what appears to be bolt configuration in line with the piston/rod line.  Here is a puzzling note... in the position you see in the pictures... I have valve lash on both the intake and exhaust.  I think it's at TDC, given the visible crank timing mark and valve lash on both valves. 
      Any thoughts ?  Does this appear to be in proper valve time ?  Have I missed anything simple ?  Thanks in advance for your input.

      Coleman 400 UTV fuel issue
      By weasel
      starts up you have keep rpms up for 5 minutes till it warms up then runs fine. But if it stalls wont start unless you unplug fuel pump and hold it to the floor till it starts then plug pump back in and run it till it warms up then it is fine all day.
