starts up you have keep rpms up for 5 minutes till it warms up then runs fine. But if it stalls wont start unless you unplug fuel pump and hold it to the floor till it starts then plug pump back in and run it till it warms up then it is fine all day.

Have you tried resetting the ECU? Likely something funky happened with the IAC settings or the fuel trim.

When running rev it to redline in neutral, and shut it off with the pedal still floored. Wait 5 seconds and then let off the pedal and restart as normal

...or you can use the codescanner method if you have the codescan cables and HUD ECU hacker

got mine off ebay, should not require any cutting if you get the right adapter.

Mine came slow boat from China, but there were domestic alternatives there for more money.

I am curious Does the 2008 Cub Cadet Tracker have this chip in the ECU?  How do I go about checking codes in it, does anyone have an idea please.

If I had to guess a model that old is likely carberated, and would not have the Delphi ECU.

Sometime in the mid/late teens is when Hisun switched to fuel injection/Delphi ECU system

      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.

      Hisun E1 Power Plug Replacement
      By John M in Louisiana
      Quick question about replacing the plug.  One of the prongs pulled out, so I'm thinking it will be an easy fix to connect the old cord with a new plug but I'm unsure about the specs.  15amp 125v?  Is it more complicated than that?  I do plan to buy a plug that's water tight.
      Thanks in advance!

      2022 Coleman outfitter 500 had a loud snap then a metallic grinding noise
      By Browner010
      Recently I had an overheating issue on my 2022 Coleman Outfitter 550 (Hisun UT550) and to check to make sure it was fixed I took it out for a ride around the block. After a couple cycles on the LED coolant meter, I took it for a couple mile ride and on my way back I heard a loud metallic snap then a grinding noise. It was still able to move under its own power but very slowly. I was about 2 blocks from the truck so 'I limped it home and up onto the trailer. I know I need to tear it apart and look for what broke, but anyone have a guess as to where to start? I'm seriously getting tired of this damn machine! 750 miles on it and already replaced the belt, wet clutch, primary clutch, clutch roller weights among a few other things. Seriously, this friggin machine has spent more time on the lift than on the road. I thought I bought this new because it was from the owner of a tractor supply, but he registered it under the stores name making me the 2nd owner voiding any and all warranties.
      Any Ideas what to look for would be appreciated.
      Thanks
