Now what?!!! Coleman 550 no start

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.

      We just bought a used 2017 American Landmaster TW450. No hour meter that I can find, so not sure exactly how much it has been used. 
      The first 2 days we had it, the starter was a little sketchy, but it started after 2-3 tries. Sometimes when turning the key, we would hear a loud metal "clink" sound. Like the starter made contact, but didn't have enough power to turn. 
      THIS MORNING... Turning the key, we hear a single click sound. That's it. Even with a new battery, the starter is still doing the same thing. Both batteries (old and new) were reading 12.8 volts on volt meter. So I'm wondering what else could be going on? Any ideas on what to look for would be greatly appreciated...
      Thank you!

      Hello, I have a 2013 500 utv hisun. Was running ok and cut out while parked. Bike will not start now. It turns over, but won't fire. I have no spark and no fuel. I replaced fuel pump, ignition coil, spark plug, cdi, voltage rectifier and all the fuses and relays. Could bad stater cause no fuel because I can't hear the fuel pump priming. Any info on where to start looking for problem.

      Take protective plate off under the rear axle brake and loosen the large adjustment bolt until the parking brake is free, Then tighten the brake cable nuts on the left cable attached to the main brake pedal until the slack is out enough that stepping on the main brake releases the parking brake. Once released, the large adjustment bolt for the parking brake assembly can be adjusted to the desired tension to keep the UTV parked when the parking brake is applied. Then it is simply a matter of adjusting the parking brake cable to allow the main brake to release the parking brake. Replace the steel protective plate under the rear axle and your are done.
