Thought I’d post this in the general forum to try and get some more ideas. 
2008 Joyner Renegade

800cc EFI Chery engine

1100mi

Starts and idles fine, drives well until you actually try to go, then starts to sputter as if it’s starving for fuel. Does this no matter what fuel pressure I set it too. I’ve tried 35-80psi 

New fuel pump

New fuel filter

Cleaned injectors

New thermostat

Fresh Fuel

Any smarty smarts out there with ideas?

I thought that too, but it’s just the super skinny tips make it look like the gaps are huge, did just pickup a feeler gauge though, we’ll see whet they are currently at. Any idea what recommended plug gap is? .035…..

What are the spark plugs gapped at? It's probably just the pic, but those gaps look kinda big. 

Gap was about .050, gapped them to .030 and ZERO difference 😕😕😕

According to my service manual, the gap for mine is 0.6-0 7mm. Not sure how that converts to inches. But, it is a moot point since you already regapped the plugs. 

.023  -  .027 thou

so, Throttle Position Sensor was faulty?  that will cause problems 

Yes, I missed it because I noticed there was a spare TPS in the glove box. Swapped em out and  it would barely run. So I put the original back on, but never actually tried just unplugging it. Once I did that, holy $hit does this thing rip!

      I have a 2013 Hisun with a 686 Yamaha engine.
      I purchased it from an individual and it ran fine as long as the battery was full.
      I replaced the stator and now it will not start (run).  It cranks fine, has fuel pressure, but will not fire up.  I replaced the coil, no luck there.
      a technician told me that it was the wrong stator and wants a mint to replace it.
      the wires all plugged in when I installed the stator.

      Hey Guys, I have been chasing a stalling condition for about two weeks now. The bike will crank up and idle fine, then after about 20 seconds it will fall on its face and stall. It happens at both idle and while running at various rpms. You can turn the key off, turn it back on and it will fire right back up without trouble. I have verified spark on both cylinders with a spark tester. I have also added an inline fuel filter, and pulled the injectors to verify proper pulse on each. Things I have replaced - (relearn procedure performed after each component replaced): spark plugs, ECU, relay/fuse box, fuel pump, & throttle position sensor - all with no improvement of the condition. The only warning light I get when the condition occurs is the oil lamp. The bike only has 14 miles. I am at a loss and appreciate any help and suggestions! Thanks

      I'm looking for an engine for my Hisun 700 SXS.
      I've found a LOT of scam sites, and need to find a legitimate business to purchase a used engine.

      This post will explain how to hook up your PC to the ECU of a Hisun/Coleman/Etc UTV to be able to read error codes & engine parameters for troubleshooting purposes.
      This is applicable to all small engines using the Delphi MT-05 ECU. This should cover all fuel injected Hisun models, as well as various other Chinese FI engines, as the Delphi MT-05 ECU seems to be the favored ECU solution.
      Even though we get actual engine error codes to display on the dash, sometimes we have “pending codes” (not yet confirmed by the ECU) or other intermittent issues that are hard to diagnose, for example a poorly connected sensor that may give intermittent false readings, or a sensor that’s putting out bad date, but not bad enough for the ECU to realize.
      The setup requires 2 cables, which are available for around $25 combined, a PC with a USB port, and some charityware software called “HUD ECU Hacker”. This gives the same functionality as the $300 dealer code scanner for a fraction of the price.
      In searching I found info about HUD ECU Hacker, but I have yet to see info anywhere about how to hook it up to a Hisun, so I took the leap and bought some cables, and made it work. I will show a step by step of how to do so in post two.
      I will be breaking this down into 2 posts:
      Delphi ECU Info & Overview (This post) System setup & use Delphi ECU Info (Skip ahead to the next post if your eyes glaze over technical details)
      The Delphi MT-05 ECU was developed to allow small engines to use fuel injection. A fuel injection system requires feedback from various sensors to operate efficiently. This feedback allows the adjustment of ignition timing, fuel injection volume, etc to efficiently and cleanly produce the most power possible from a given engine.
      The MT-05 ECU has a number of sensors that are required for proper functioning including; Coolant temp, crankshaft position, intake temp, intake pressure, exhaust O2, throttle position, as well as some other optional sensors that are used on more complex vehicles.
      From the sensors the ECU adjusts: Fuel injector timing/pulse, Idle air control valve, and ignition coil

      The Delphi MT-05 puts out diagnostic data, however it is not ODB2 like a modern car, where is where it gets tricky reading it. There are three options, there is an old 16 bit piece of software Delphi has that is not able to run on a modern computer, there is the motorscanner tool for dealers ($300), or there is freeware HUD ECU Hacker with the proper cables.
