Coleman 400 UTV fuel issue

[weasel]

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

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.

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.

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
