Tried it again and this time it worked, but I had to floor it to get it to start, but at least it started, I've been trying to get it to start using the first part of the throttle, but when I pull it or coast it, I end up floor boarded so I should probably start just flooring it and see if that works. When I try to start with minimal throttle, I ofter notice the smell unburnt gas. I did get my malfunction light hooked up and once the engine is running, it goes out, tried unhooking a few sensors and the light came on.

Good work on the fault code light. Now if we can find a scanner that will read the computer for diagonistic we will be all set. There is not a plug in recepticle for the scanner but the terminals for it are on the compuuter and the schematic for the Trooper shows the plug and which pins the scanning leads from the computer go to, so we could get one hooked up. I'm thinking that a lot of standard scanners would work being that it is a Seimens or is it Bosch computer. I dought that they set up different codes for all the different cars. A lot of the car computers look idenical although they may have different call up tables telling them how to respond to various conditions, they probably all have the same code for same sensors not working. Anybody have any thoughts on this.

When I take my Yukon for for safety and emmissions testing, the tech plugs in the vehicles computer and get all the info, I think he has just the one plug and I bet they are standardized. Ours should follow, I'll look around and call him.

Any one want to set up the Malfunction light? it's easy, I picked up the +12 volts off of the battery at the winch relay, put a 1 amp fuse inline with a 1000 ohm resistor and a red LED to the blue wire and duct taped it to the computer cover. Can't see it while driving, but that can be changed quite easilly too.

Hi , I believe that joyner system diagnostics are obd2 compliant,they should have standerized trouble codes . It would be pretty easy to wire up you can buy obd2 connector just need power,ground data line terminals added to the connector and use a generic code reader .With some research Iam sure we could find a laptop based program and cable lead to read actual data streams

Kinarfi, maybe you could slplit out the talk here about computer diagnostics and put it in it's own thread. That way we may get more input and could resolve the problem for once and for all. Looks like we may be getting close.

Kinarfi, here is a site showing someone having a starting problem. I figure everything can possibly be of help.

      Hisun Axis 500 Problems - Hesitation, struggles to go up incline, and low speed regardless of gear range
      By AlphaSerenity
      Hello,
      Before I invest $10k+ into a brand new UTV for the farm, I want to get my feet wet with a fixer upper and learn the mechanical side of things. I acquired a 2022 Hisun Axis 500 (Lowes-specific model) from an auction for $500. It has only 200 hours and 120 miles on the engine. It looks like the previous owner used it for ranch work and didn't drive it on trails, deep water/mud, or anything too crazy.
      While it runs and moves, it has some problems. It struggles to accelerate up any incline in high and low range and sometimes stalls when I let off of the throttle or change gears. When I apply throttle in neutral, it sounds like it is struggling for fuel/air and pops. When I decelerate, there is a grinding sound coming from the clutch, which I've read to be related to the one way bearing and is semi-common. The last thing I've observed is sometimes the speedometer display sometimes will show a much higher value for a few seconds after barely touching the throttle. Based on the documentation, if a problem is detected from the sensors, the instrument panel display should have an error code rendered on the screen in place of the time, but this isn't happening. Here is a video showing some of these issues (engine is exposed with console removed):

      Here is another video of the clutches in action:
       
      I've done some research, but information on this specific unit and sister units is limited. There does seem to be transmission and clutch issues reported. I still need to check into the head gaskets. I don't have the equipment to test compression right now, but I do plan on ordering what is needed soon. I do have an order in place for some cables to read the diagnostics from the computer. There is a shop two hours away from me that works on Hisun products, but I am hoping the problem can be identified and is something within my ability to handle. Below is what I've already investigated.  I am leaning towards the primary clutch needing replacement right now.
      After getting it home and unloaded, I did the following maintenance/checks to it prior to operating it further:
      Changed the engine/clutch oil (and filter) and gear oils using manufacture recommended viscosity Changed the air filter and checked for cracks in the air intake flow. Verified good suction. Cleaned the throttle body Changed the spark plug and verified the gap was within spec (0.6-0.7mm) Changed the coil and coil wire Changed the fuel lines, fuel injector, and verified the fuel pump was outputting the correct initial prime pressure for ignition and continuous pressure after ignition. Also completely emptied the fuel tank and made sure octane 91+ fuel is being used per manufacturer specs. Ran seafoam through system too. Cleaned the spark arrester and verified no cracks or gaps in the exhaust flow Changed out the O2 sensor Checked all wired connections to ensure they were secured and no breaks were visible Checked the belt for tightness and for any signs of wear and tear Verified 4WD and the differential lock function as expected - still hesitates and struggles uphill Verified the fan gears in the shifter are not corroded and working as expected ECU was reset after replacing sensors and fuel-related parts  
       
      Thanks!

      Only stays running when I throttle it dies at idle Colman 400 utv
      By Richard shepard
      I have a 2021 colman 400utv engine will start and idle, as soon as you hit throttle to move engine dies and will only start when you throttle it, let off throttle it dies, I replaced the injector and plug still the same, anyone have any other ideas

      2016 Hisun 500 turns over,no start
      By Felderlostnspace
      2016, Hisun 500 turns over great but Spark plug is firing when I turn the ignition key on. I’ve got good fuel pressure to the injector. Pulled plug out and it is wet with. gasoline. Air filter is clean. Turns over great just does not even try to pop or start.. I’ve checked off uses and they are good when I turn the key on I’m getting power to the injector.. I’m not hearing the injector pulsing, but may just be my hearing.. With the spark plug getting wet with gas I feel like the injector is pulsing and spraying. Any suggestions would be great. I don’t know the hours on the unit offhand, but it has 600 miles on it. Thank you for your comments and advanced.

      Greetings from Southern Illinois. My name is Bruce and I currently have a Hisun HS550 Performance Rural King. I have had nothing but problems with this unit replaced so many parts of it and of course, it stopped working and will not start again for about the 3rd or 4th time since 2018 it only has a little over 500 miles and has cost me a bunch of money and headache and the Rural King where I purchased it has a repair man who is certified to work on HISUN but he charged me a little over $600 to repair it once back a few years ago and when I got it home after it being in his shop for over 2 weeks the thing worked for a very short time but when I went to start it the next day it was the same thing and they wouldn't check it further without me paying for service, labor, and parts and I went around and around with them and since there aren't any dealer service centers for Hisun near me and even most of them can't get to it for weeks to months and it could be at their shops for months as they tell me they have problems getting the parts needed from Hisun to fix these giant paper weights. Oh, and you can't buy a scan tool (code reader) Delphi 190121 unless you are one of their dealers and I can't find any other scanner tool that works with it except the Tiny Scan Tool which I purchased and it will work if I could find the correct adaptor cable and connector to connect the Tiny Scan to the diagnostic port on the Hisun HS550 Performance Rural King. Yep, I pretty much have been screwed every which way that can happen with this machine. I am disabled, have cancer, and am on a fixed income so I need help if anyone knows what the connector is called (type or part name) that will plug into the diagnostic port to get my scanner to work it is a 6-pin connector and I hear it only has to have 3 wires connected to it.
      Thanks
