Anybody know what would make the coil not fire? I bought a brand new coil and still no fire...

You said you down loaded the schematic for the computer under manuals in the parts and pieces sticky( http://www.utvboard.com/topic/392-parts-pieces-and-information-for-our-troopers-joyners/page__view__findpost__p__475,)

If I had your problem, I would pull the spark plugs for easy turning the engine over by hand, unplug the computer, turn the key on to run, and check the voltage on pin 67 to see if it has power, if so, jumper it to ground to bring in the main relay, pin 67 is the ground pin for the main relay.

Now, jumper pin 27 to ground, this activates the crank shaft position sensor, now measure pin 29 and watch for a pulse as you or someone turns the engine over slowly, use a voltmeter or an oscilloscope, not a test light, I don't know how much power the sensor can handle, maybe an LED with 1K ohm resistor would work. If you get the pulse, this means the sensor is working, it is what tells the computer where the crankshaft/piston is. If it doesn't pass this test, you may have a bad sensor.

If this test passes, hook the computer back up and watch for a pulse, on or off, at pins 4 & 5 to see if you're getting power to the coil as you turn the engine over slowly, you may be able to measure this at the plug going to the coil. If it doesn't pass this test, You may have a bad computer.

Keep posting your results.

      By Charles Hines
      I bought a 2021 Coleman 400 UTV from Tractor supply mainly because of the $2000 off black Friday sale ($6999). I wanted something to do some light hauling around the boat shop and figured this would be a better choice than a golf cart. Initial review is that for the money,it's got to be the best deal going. Fully equipped right out of the box with a lot of nice features. First off,everything worked,that's a good thing. First thing I noticed is that this thing is LOUD,so loud that I use foam ear plugs to run it. The rear axle is locked,like most 4 wheelers,so the tires scrub on tight turns and will tear up the lawn. I found some loose bolts and did a general inspection of everything and tightened up the loose ones as I found them. It's cold here in SE Michigan and I want to do some recreational use during the winter. I bought a 3 Star door and rear window soft enclosure and installed it. Top quality materials and fit great. I added some foam to close off all the gaps and it really does the job. Next I added a Ice Crusher heater kit that uses the coolant to provide heat in the cab. Quality parts and the kit was pretty much complete,I also added a coolant shutoff valve so I can direct all the coolant through the heater instead of the radiator,or blend it as I wish. The heater has a 3 speed fan and 2 directional outlets for this model and with the enclosure will warm it up to shirt sleeve temps at speed with the outside temps in the low 30's. I also added a Kolpin Stealth 2 auxiliary silencer, the exhaust note is definitely quieter and less raspy, but this rig is still noisy enough at speed that you need ear muffs or plugs. I changed out the headlight bulbs to LED's which are a big improvement from the halogens. I figured out a trailer hitch adapter for the oddball thing Colman provides. Now it's just run it in and break it in. For a 400, it is actually quicker and faster than I expected,the specs say 38, but it's closer to 50. Brakes are powerful and smooth. The solid rear axle makes this thing pretty capable,but you also have the push button 4 wheel drive and a push button front diff locker if you need it. All in, it's set up just the way I wanted it for under $8000.

      New 2021 Hisun Vector owner- Snow plow recommendations?
      By porterpowered
      Hello everyone! I would appreciate any recommendations for a snow plow for our Hisun Vector. Nothing fancy, just something to plow our hunting cabin's driveway. I'm having difficulty finding something that fits. Thanks!

      Landmaster EV Lithium (new) refuses to move
      By Lionel
      I purchased a new Landmaster EV lithium. I have only had the vehicle for 5 days. From nearly the first day, it intermittently would not start, either forward or reverse. After waiting a few minutes, it will go in reverse, but not forward. After a few more minutes, it will go forward. This happened several times over three days, and then it had a bigger problem. It would not go forward at all, and I had to drive it in reverse for 400 feet. About 30 minutes later, it could go forward. I called the dealer and told them to come and get it. Does anyone out there have this model? Are you having similar problems?

      still going
      By Joe Breaux
      just an update on my MSU 500 . For all the misery it caused me the first 2 yrs, and the combination of some quality YAMAHA parts, it has now become a reliable ,useful UTV without the constant fear of having to push or tow it back from trails. I have not had a single issue pop up in a very long time.. FINALLY!....and as a side note, I just bought  a C FORCE 600 ATV to replace an old and well used  Honda that finally after 18 yrs gave up a rod bearing.  So far the new one has really impressed me .. I like the new Power Steering and  this CVT Auto Trans is new to me on an ATV .. I m used to constant shifting on my Hondas .  It also has something I have never seen. Its EBS  engine brake system, as soon as you let go of throttle, it engine brakes you to a stop rather quickly.. its great idea for the grandkids safety . Takes a little getting used to tho.. All in all, I like it. We shall see how durable it is after break-in.. I do "RIDE" them! .....and they honor their warrenty! and the dealer is 15 minutes away..
