Depends what you mean by "doesn't want to rev up". If it barely revs faster than idle, it's probably in limp mode which means the ECU is protecting the machine by preventing if from rev'ing because of some error.  Since the machine was tipped on its side, it's possible that there is air in the radiator hoses, which is fixed by burping it: raise the front wheels at least 20 inches off the ground and idle the machine with the rad cap off while adding coolant until all air bubbles are out.

      Coleman UT400 won't rev. Idles fine
      By Will Sutton
      I've got a 2023 UT400 (bought from tractor supply) and I've been beating my head against a wall with it.
      It will start and idle perfectly. The second I touch the throttle it sputters and dies.
      I've checked that the fuel pump is working  (it is).
      I've replaced the injector, throttle position sensor, O2 sensor, and intake air sensor. All with no change.
       
      I've just taken a look a the schematic, and there is a crank position sensor as well.

      Could this be the source of my troubles? If so, where is this thing located? I can't seem to find it on any drawings from the parts suppliers.

      Axis x550 02 sensor on right after buying the UTV.
      By TPlummer
      We recently purchased the Axis x550. Fueled it with 93 fuel and drove one time around the farm and the 02 fault error appeared. Any ideas?

      Now that I have done the LI-Ion batt conversion, I need to do something about the suspension
      By Kingfish
      The conversion took about 350lbs. off the vehicle.  It never rode great, but now I feel every  crack in the road.  I have backed off spring compression nut to the point just under where they would move around if suspension was at full extension, but it is still very stiff.  I would like to put some softer coilover springs on it, but I have no idea what the spring rate is with the original springs so I would just be guessing on what to order.  Does anyone have the data for the original spring compression rate?  I am willing to give up a little ground clearance for a softer ride. Right now when sitting still the rear suspension is at or near full extension and the rear tires have several degrees of camber which will cause uneven wear if allowed to continue in this state.
