Good grief...just got back from a 10 day camping trip. Took the trooper, it ran fine when we loaded it. Unloaded it in camp, started it a couple of times to move it, all was well. The next morning, hubby went to start it again, and it would not fire. We've been browsing the site for others with the same problem, and nothing quite fit the symptoms we had. But, hubby (Lloyd) took all electrical connections loose, cleaned them, etc. No burned wires, no blown fuses, no burned relays. The only thing he found was very dirty sensor (I forgot which one he said it was). After putting it all back together, and with the help of some starting fluid, it fired. He's still not sure he fixed it, but I wanted to let y'all know we found the places to trouble shoot on this site. Thank you all for sharing your knowledge!

Hello

You need to go back to basics.Is the fuel pump running and do you have fuel pressure at the gauge.Pressure should be at 50 PSI.Take off fuel line of and see if you have fuel coming out of fuel line.If that is good then check for spark pull out spark plugs and ground out housing see if it has spark.If so then get back to me 928 344 2117.Az time call 9:30

Hey Silver Bullet, thanks for replying! Yeah, Lloyd did all of that right off the bat. He checked fuel pressure, fuel pump functioning. The only thing he hasn't done is check for spark, but it fired. Then he let it come up to operating temp, took it for a short ride, shut it off and then started it again. It fired again. He started it several times, and it's been starting since, with no problem. He said it was the MAC sensor that was really dirty, if that has anything to do with it. He said he might call you tomorrow concerning the ignition. If he turns to the accessory side (did it by accident when he was starting it and shutting it off) - to the left, the starter engages. That's obviously not supposed to happen. Do you have one, or an OEM replacement?

THX AGAIN!!!

I went to Oregon to the Dunes for a week.The Joyner started normal than when i got to Oregon and it was Damp out in the in the morning and it would not start.It was just the damp weather.I had to use starter fluid than every morning it did the same thing till i got home.I guess it just doesn't like that weather.

We had rain 5 out of 10 days, and high humidity the rest of the time. Lloyd had to use starting fluid to start it when we got home; something we didn't take with us. Then when it did fire, it blew black smoke like a diesel. It's running now, thankfully!

More starting issues - it seems the buggy doesn't like cool mornings for a change. It will whirl but not start if its close to the freezing mark. After the day warms up, it will start with no problem. A simple pull with another vehicle and it will also start with no problem. New plugs, new battery, etc have not seemed to help the matter. Any ideas gang?

My 08 Trooper acted the same way when it's rings were worn, it wouldn't start with starter, but would start with pull or coast down hill and once warmed up, it would start & run just fine.

Check you compression.

How many miles on your rig? Look inside your intake tube, is there any dust?

Thx for the reply Jeff. Lloyd can give it just a little throttle and it starts as well. Seems kinda strange. Will check compression for sure. 18k kilometers on the buggy, no dust now but there was when we first got it before we upgraded the air filter. Lloyd changes he oil regularly, cleans the air filter nearly with every trip out to keep dirt out of it. Not foolproof, I know.

Adjust your butterfly/throttle screw so it idles or replace your DLA, Page 106 of 2008 manual, see attached. My DLA died long ago and I had the same problem, I adjusted the screw and had no problems since.

Also, another idea for you is to add a light to you ECU, pin 70 to tell you if you have an engine malfunction (check engine soon light)

See the last few entries -- https://drive.google.com/folderview?id=0ByQAhs0e-yF9ZjNtc1JlTEVpQ0U&usp=sharing

If interested, let me know and I'll explain how I did it.

All the above ideas sound good.I did not see if you checked the compression.It sure sounds like compression.With not having it i can not tell what is wrong.If you have done It.Then may be electrical.Or censer's

Thanks Matt

      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.

      My Axis 500 has been operating properly for almost a year with Zero problems. While I was away my granddaughter & friends were riding & playing in the snow. They went to the gas station to fill the tank & the vehicle would not start afterwards. I BEEN GIVING MULTIPLE STORIES: The ATV will not start. When I turn the key I can hear the fuel pump come on but nothing happens other than that. 
      - NO CLICK - NO OTHER NOISE
      *I CHECKED THE BATTERY 12.43volts
      *I replaced the solenoid inside the battery compartment. 
      Seems the next electrical component in line has battery connections IN & motor connections OUT with 2 other small wires connectedaswell(I do not know the name of this component).
      Can anyone help?
      I can not find an ordered list of electronic components starting at the battery.
      Can anyone help with this?
      Thanks in advance for any help.

      Does Anyone by chance have a owners manual and a shop manual for a 2007 800cc trooper. I just bought one and need to figure out where and how to engage and disengage the 4 wheel drive. Is it electronic or is there a hidden lever. PLEASE HELP
