Died at idle and no start


Recommended Posts

Last October we were sitting at an idle on a Sunday morning and it died for the first time since we time since we bought it new I've already sent it to the shop because it's under warranty after trying to fix it. New fuel injector new spark plug couldn't do a compression check because I couldn't find anything to fit it but now that it's at the shop I have a feeling that the exhaust valves tighten themselves up and they are not closing anybody ever have this problem?

what model is it. This can be a few things, of course the three most basic things are spark, fuel and compression. Its pretty easy to check for spark, and fuel test is also easy to test. You only need to use a compression tester for motorcycles/atv as they have the smaller adapter needed for some of the small openings in the cylinder head. But on a guess it should be putting out in the very high 165 or more.

shop said zero compression. Upon further inspection found timing chain very loose and said it needed a cam tensioner. Hisun wants the maintenence records to cover the warranty so I'm trying to find receipts from 6 months ago. But I will keep yall updated

 

BTW its a 2020 hisun sector 750. 

As soon as I get it right I'm getting rid of this dump and getting a Polaris. I should have known better than getting Chinese crap

Exactly thats why I was like wth man. Its got 161 next oil change isn't until 200. I think I'm just going to pencil in the maintenance log at the back and that better work. These people are ridiculous; 160 hrs out of a 15k machine I mean come on. I am going to report them to the bbb

according to the factory owners manual, you are required to perform an oil change at 50 miles. and the next service is not due until 250 miles. But none of these have any bearing to a faulty cam chain tensioner. I think the dealer is the one pushing back not hisun. Hisun has never asked me for customers service records. Even though they can, it is very rare. The dealer is the one asking. In the owners manual it states: As the vehicle owner, you are responsible for the performance of the required maintenance listed in your owner’s manual. HISUN recommends that you retain all receipts covering maintenance on your vehicle, but HISUN cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance As the vehicle owner, you should be aware that HISUN may deny your warranty coverage if your vehicle or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications. You have not done any abuse, you did not neglect this uvt, you did not do improper maintenance as well. Lack of a timely service is not improper maintenance, simply late on the service.

Sorry I just seen this. But I gave them the receipts and they covered it under warranty. Rebuilt the whole motor. Should be ready to pick up this afternoon. Thanks for the input strike, I'll let you know how it pans out. Hopefully we get it back before the foot of snow next week. Would love to ride in it. We never see any in east Texas

      Hi I have a 2008 Joyner Renegade that died and will not re start It had been sitting for about 2 months while I waited for a new rear diff and then finally found time to work on it. It started OK after I filled it with gas and charged the battery. It started and ran for about 5 minutes and died I pulled the outlet line off the fuel pump and am getting lots of fuel the engine It has electrical power to all circuits as near as I can tell. Any schematics I have found are microscopic and when you expand them they are written in Chinese. I found one fuse box at the right front frame Who knows what the fuses are for They are not identified on the panel or cover. I replaced one fuse and all others were good I found some fuses and 3 relays tied up behind the battery Switched relays around and made no difference. There is a huge 40 amp fuse in line I cleaned the corrosion off the terminals on it. I still have the same issue It is cranking over, has fuel delivery to the engine but is not firing
      Is there another relay/fuse panel I am missing? Does the system use a TPS and or crankshaft position sensor that could be the culprit?
      Does anyone know of an on line service manual for this beast
      Thanks for any assistance

      Hi friends, I have a new utv Hisun 700. My problem is idle adjustment.  How is idle adjustment done? While my engine is idling 2500- 2700 rpm. I need idling adjustment 1500 rpm. Where I am, there is no master who understands this tool. How do you do the idle setting? Can you help me? Hello everyone. Thank you.

      2007 Mule 610,  owned for 8 yrs and valves were ticking when I got it and had them adjusted twice and this is when plugs began to foul.  I replaced battery (used battery I had on hand) a yr ago and didn't foul a plug for some time and replaced batter (new) with a bigger lawn mower type battery again a month ago and have fouled two plug since.  Had carb cleaned and valves adjusted and still fouls plugs way to often.  Friend has a mule just like mine and his does same thing. Have read this is a common problem with 610 mule.  Any help or suggestions would be welcomed.  Thanks and stay healthy.
