Have you checked the digital clock on the dash for codes?

A lot of the models made in the last decade or so, blink the clock, and you count the blinks, to get the code. Others will display a digital number, that represents a code on the clock instead.

I haven't seen any blinking, no. I'll double check though.

Sometimes it's displayed as a number on the clock. It might not blink, but just display the number. I don't know how many sensors there are on yours. But with what's going on with yours, there should certainly be a code. Have you looked at switching the upstream, and downstream exhaust sensors?

^^^this^^^ The codes display just like the clock display, but the colon (":") is dimmed out--they are easy to miss except that they do not change each minute--The EPS  (Engine Protection System) warning light should be on if any error codes have been logged.

I haven't seen mention of the oxygen sensor (in the exhaust pipe)  in this discussion.  A dead or dying O₂ sensor will  generate a low, or no,  output voltage; this makes the ECU think the engine is running lean, it compensates by adding fuel, I.e. making the AFR rich. This can happen without triggering an error code.

For more (than you probably want to know) about O₂ sensors--including how to test them with a multi-meter and a propane torch--click here.

Well there were no flashing lights on the dash. We think we resolved it though, we replaced the injector and it's running much better. Maybe something got stuck in there? Hopefully it stops burning through plugs now. It still has it's hiccups like wants to stall if sitting idling sometimes and hot, and i stomped the throttle once when colder and it had a good bog. Definitely doesn't run like new.

If you find out the problem please share.  Mine is do the same thing. I have replaced all the electrical components and still doing the same thing. The only thing that I have not replaced yet is the wiring harness. My 02 sensor is also shooting sparks out when starting.

Changing the injector seemed to have fixed it. We ended up selling it this spring.

      I just bought a new 2024 Hison 550 Stryker 2 months ago. this is the second time I have had this issue.  It only has about 20 hours on it. The last time it happened we took it back to the dealer. it was a fuse.  Since we live three-hour time driving there and back. I would like to find another solution if possible.  I have tried all the fuses that seem to have anything to do with starting.  Currently checking the battery. The battery is new. it came with the unit. It is probably 6 months old.  the UTV has all power to everything electrical. lights turn signals and radio all work.  When trying the key to start . it is 100% dead. as in it doesn't even click.  There is a low whirring like the fuel pump is turning on though. The Unit was running and driving just fine.  we shut it down for the night. The next morning my wife found it in this condition.  Thanks for any Ideas or solutions???   Otherwise, it goes back to the dealer tomorrow. Just hope I didn't buy a lemon. Great little UTV when it does run.😅  anyone else ever have this Issue..?

      I turned off the key and then tried to start it a minute later and it would not start. I changed out the fuel filter and the injector. still nothing. if i have the injector pulled out and close to the hole the injector will spray fuel into the hole and it will run but the minute you put the injector in it will die. any idea's please

      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.

      This mod is not for the fainthearted, as it requires some basic metal fabrication and welding skills.  But the result is worth the effort IMO.  I chose an aftermarket Honda Talon windshield based on economy, size, and construction (aluminum frame, DOT glass, folding, windshield).  It fits OK, a little narrow at the top, and you need to incorporate the lower section of the original acrylic windshield and build some additional plates, but better than being too wide.  If you are wondering why I attacked this mod, it's because mine is driven daily on the street.  Tired of fading, scratchy, hazy plastic.  Sucks in the rain; sucks at night.  Now I can see.

      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!
