2019 Coleman Outfitter 550, 160-ish hours. Was driving it slowly and it just slowed down and died. Won't start. Pops once as soon as I start cranking and that's it. I have great blue white spark on the spark tester, jumps 1/2". Changed injector, no joy. Changed plugs to new several times, no joy. Pulled injector power wire and tried ether through air intake after removing air filters- nothing! I do notice if I put my hand over the air intake where the filter goes, I get pressure  pushing back at me. Jumped time? Stuck valve? Is there a decompressor on this that could be malfunc?

 

This is the one I've had that was inop for months and months while Coleman tried to find someone to fix it. Warranty is long expired now. I'll never have anything good to say about this thing.

I don't know how hard or easy it is,  but i would pull the valve cover off and check the operation of the valves for that cylinder, if you can find a way to rotate the engine by hand, should go  Intake valve, (compression, both valves closed) power (piston going down) exhaust valve opens (piston travels upwards).

I have the same issue with my Coleman Outfitter 550. I have less than 100 hours on it and it spent months in one of "Coleman's certified mechanics" garage without the issue being fixed. It does not run. I bought this UTV because I have bought Coleman for years because of the Coleman quality but I have lost faith. I need help. I am disabled and spent $10,000 on something that Does. Not. Work. I've tried to contact them about it with no luck. It's a shame, I've never bought anything new in my life until now and I might as well be buried in it because it won't run and Coleman won't help. I have NEVER heard ANYONE say ANYTHING good about it.

An update- I pulled the box off so I could access stuff. Checked the valves, both appeared to be at the recommended clearance, forget what that was. Then pulled the injector and checked for fuel spray, got it. Then pulled injector off the fuel line and checked the flow, got lotsa gas fast, no idea on fuel pressure though. Checked spark again and with another new plug- good blue spark. I tried giving it a sniff of ether through the injector hole and she fired. did that a couple times and she certainly seemed to want to run. So I put everything back and gave it a try. She spun and spun and suddenly sounded like she wanted to start, so I kept going and it did! I ran it around for 15-20 minutes and got her well warmed up. I still had that thing where it would get to about 5 or 5500 rpm unload and it would die. It would run up to the 6-7K area with no load (in neutral). I was thinking the fuel pump may be weak or the filter on the pump might be clogged a bit. Got looking around and found "The Motorcycle Doctor"s website. There I found the instructions on how to reset the ECU and injection system. That was "Clean the O2 sensor first and then warm it up good, run the engine up to full throttle for 5 seconds and shut it off at full throttle, wait 15 seconds and restart and drive it around at varying speeds and loads"  according to the instructions.  I did that and after some spitting and sputtering I was able to run down the road in excess of 40 mph at about 6500 rpm, which I haven't been able to do since it was new! I still get the bogging, like it's either triggering the retarder in the seatbelt system or maybe running out of fuel. I still wonder about the fuel pump. I don't the gauge and fittings to check it.

 

At this point I'm further ahead than I have been for some time. I'll update as I work on it.

      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.

      Is there a code reader available for the Coleman UTV 400?  I tried using the HUD ECU Hacker software and cables/adapters but no luck OBD to delphi 6 pin and KKL VAG as well as ELM327.  Will not connect.  I was able to get it to connect randomly a couple of times, but haven't been able to since.  I was able to clear and read the codes briefly.  I'm aware of the Tiny Scan 301 but it doesn't seem to be readily available.  There's a few out there but they are expensive.

      I'm thinking of buying a snow blade for my Coleman Outfitter 550 (Hisun with Coleman stickers).
      Has anyone purchased a snow blade that can offer the make and model they bought and any comments, pros  cons etc.?
      Not 100% sure I'm going to buy, as the selection of blades for this model seems a bit thin on line. 
      Thoughts and comments welcomed.
      Thanks in advance.

      Hi
      I have a 2022 hisun sector eps 550. 30amp fuse is blown for eps. Checked the motor and it’s fine. Opened up the controller and found a bad diode. Dealer wanted 500$ for the controller. Just posting this in case it helps someone. I couldn’t read numbers from the old one so just took a guess and replaced it with a 100v 3amp diode.

       I just picked up this project that I was told would crank, but not start.  This is what I’ve figured out so far….
      I installed a new battery and get all dash lights, head lights, and brake lights on when turning the ignition on.  Fuel pump even turns on.  It does not crank with the key, but would when I jumped the starter solenoid, so I replaced it…..no change.
      Figured I’d check for spark and compression while I was dorking around.  Compression is 150 psi, but there is no spark.  Replaced the spark plug… no change.
      So, is my new starter solenoid bad?  Could it be the brake or gear position switches even though the brakes and neutral lights come on?  Not sure where to go from here.
