Check the downloads section here, should be a service manual for your machine in there.

Nope!

It could be moisture in fuel, not uncommon. For future reference , I burn nothing but highest octane in mine and use good quality fuel such as BP. Hisun 550 and runs like a champ. Good luck buddy!

Hello.  I purchased this unit as a "non runner" with the intent of using the frame to build a go-cart, but once I got it home it seemed way to good to part out.  The motor cranks over, and I have spark, but no fuel.  If I put a little fuel in the cylinder it fires up until that fuel is burnt, then of course it dies.  The fuel pump is not running and I have removed the plug and there is no power going to it.  I have checked the safety switch on the brake pedal and its fine, I have checked the fuses, all good, but am not sure where to go from here. The shifter is missing on the unit, but the indicator light on the dash shows its in neutral, and the e-brake indicator switch is working as well.  I am thinking of jumping power to the fuel pump next to see if it runs and if the motor will start.

What am I missing?  What can stop the fuel pump from getting power to it?

 

 

Just for the sake of knowing, can you attach jump wire from positive side of battery to pump and see if it stays running?  You might have to find a hot wire when key is on to by-pass. Just a thought?????

Hi Randy,

I'm interested primarily to have a way to identify problems and ensure I maintain it in tiptop condition.  It is a 2019 that I purchased back in August and had 45 hrs run time. About a month after purchasing it, it was running rough.  I have replaced the fuel injector, put an inline fuel filter and new spark plug all of which made a huge difference. It then began to run rough again so I replaced the injector. Ran good, then starting doing it again. I noticed that it was doing this when fuel level was low so last weekend, I cleaned out the fuel tank and checked the fuel pump screen. Really didn't find anything that would indicate a fuel/tank problem though. The recurring issue right now seems to be when starting first time in morning. It will run fine while start up diagnostics are running, then when the amber check engine light goes off, it dies. Yesterday, it took a few times then ran fine and did perfect throughout the day. Probly put about 1 hr run time yesterday.

The other issue I was having was when starting it would act like it was coming up on compression stroke and starter was not strong enough to overcome. I reached out to Motorcycle Dr (eBay) and they recommended checking the springs on the De-compressor. I did and found one of the springs looked to be overwound so I replaced the Cam Gear and also installed a new starter solenoid while I was at it. It still does the same thing but just not as often now.

 

Wow, this is another obstacle that may hit me one day? Mine is a 2019 too and was brand new when  I bought it, 30 days later it was in shop for a month, they said it was a drivers side seat belt safety issue, I was told that they replaced the seat belt assembly and that cured the problem, come to find out, they did not replace anything.  I returned to dealer to look at their work order on it and surprisingly they lost that work order. In other words.., they lied. Took it to a local mechanic and he fixed it within an hour. Clogged injector, blew it out and it ran great for about a month, then same issue, I pulled injector, blew out the port and injector and runs great again for about another month, called  local mechanic for any advice and he told me to run premium fuel, higher octane and see if that helps,  that was several months ago and it’s been running flawlessly so far! Sounds like you having same issues, might try higher octane and see if it helps???

Thanks for the Video Ridge Runner. I haven't looked to see if I have that connector yet, but from some of the responses, it is most likely that I do not. There is a code reader that is mentioned in the owners manual (will have to go back now as I can't remember name) but I've not been able to find anything on it. 

I have contacted Hisun themselves in Texas and all they will tell you is to contact one of their dealers for help, when I contacted them for my issue, they told me that they are trying to learn themselves how to work on them and they charge $125 an hour to “GUESS” at my problem.  I asked dealer about codes and how to do diagnostic and their answer was We Don’t Know....... yet?? I’m doing my own troubleshooting and luckily, mine had been fuel issues and that’s not to hard to figure out.  A learning experience but so far it’s still running ok!

👍

Ok.   

I have watched several videos on mine and on Coleman’s. They do have some similarities but unfortunately for me, that port doesn’t exist in mine. I wished it did but as of now, it’s running flawlessly.🤞

Yep, I have no such connector, none that I seen so far and I’ve been over every inch visibly as possible without dismantling.

Might help a bit to know what issues you’re having, if any? If none, then finding the port might be tough. I’ve looked everywhere on my Hisun 550 and had no luck. Hisun sure won’t give you no support! Great machine when it runs.

Howdy Everyone,

New member looking forward to learning and sharing more about UTVs. I have a 2019 Coleman Outfitter with the Hisun 550 engine. Does anyone know what Code Scanner will work with it ?

Finding the connection port would go a long way to solving the mystery. If you go with the TS, keep us updated. 

I’ve had  a 550 for 2 years and I’m still looking for it

Interesting problem.   My Massimo runs great - but when the fuel level drops just a bit, it just stops.    It restarts easily, but I have to keep my foot on the accelerator pedal.   When I top it off with gas, it again runs fine.   I already replaced the fuel pump, but that didn't work.

Thanks for your help!

Try blowing out injector.  Mine  did same thing. Had plastic particles in it I’m guessing from inside gas tank as it’s all plastic anyway, maybe a burr from injection machine that form it??  Mine since idles fine after warming up a few seconds. Hope this info helps!

Unfortunately Mick, Hisun will provide you with little to no info. They want us to depend on their dealers to handle these sub-par machines. I’ve had issues with mine in the past and when you contact the requested dealer, they admit that the are behind in their work on these because they personally don’t know enough about them themselves! At least they were honest enough to tell me and at $125 an hour, you can’t afford to have them fix it and let them sit at shop for weeks in end till Hisun finds the issue and pass through info onto dealer’s technicians.  I found a local country boy who works on arc/tub’s out of his garage and he fixed mine up within couple days. I know you perhaps don’t have such a local -yokal in your parts, but Hisun techs won’t give you time of day on these. I’ve filed complaint. with BBB as to warn potential buyers to do extensive research on these! It’s a fine machine when it runs otherwise it’s a piece of junk!  Chinese Crap!  Sorry I can’t offer a motive CPU orcrank sensor would be a starting point? Good luck.

Sorry for spelling , i meant atv/utv’s

Well I have tried everything I can. Called the dealer I bought in from just a few months ago and less then 500 miles. That are a month out and I cannot take it there till the appointment. I explained to ruthenium all the issues I have had already and there suggestion was to take to a different Hisun dealer!!!!  Wow!!!  So guess that’s what I will be doing. They too are a few weeks out but are happy to look at it. Apparently they get a lot from other places that don’t want to deal with these machine. Wish I would of done a little more research on this brand of side by side now.

My understanding about the blinking clock, is that it does it automatically. Whenever it encounters a fault. Fixing the problem is the only way to stop the blinking. So it sounds like it hasn't encountered a fault.

That's why I mentioned the CPU. If it were a position sensor, you would've definitely noticed, and likely mentioned the blinking clock. 

I have no idea where to find the code reader port. My guess would be that it's under the dash. All that I've seen on the reader, seem to indicate that it's a Delphi type.

Do you have a service manual? One of our members has been kind enough to offer free manuals to others. I know that he was providing manuals for the Massimo. You might see if he's able to provide the one for the Hisun. 

If you're interested, then hit Strike 250 with a p.m. and ask about availability. 

I found a plug in port on mine under hood by radiator. Not sure if that the diagnostic port or just an adapter for power supply????

Personally, ( & I own one) these thing are junk! The suspension and body/ frame and steering work well but the schematic on motor are worthless! Chinese crap but I’m like you... mines a 2019 with 400 miles. 3 weeks after I bought it, it was in shop for 2 months! I’m considering switching to carburetor for mine and do away with efi. Motor runs good when it runs!

Sorry, meant to say schematic on EFI are worthless. Motor runs fine

Welcome to the forum!

I don't know what the ethanol mix in your area is. But ethanol in the fuel can cause injector problems also. Not saying that it's the actual cause of your issue. But it's very possible. And certainly worth looking into. 

I was told by mechanic that did first initial repair that these motors need  good grade fuel such as BP, Mobile Oil, Chevron, Shell etc,  plus a higher octane would improve performance greatly.

I had to put a new injector in my 2019 Hisun 550 at only 250 miles. Now at almost 500 miles it started actin up again. Haven’t looked into it much yet as it just happened last night. But have heard that injectors a a big problem with these. 

Hi Mick, after my first issue, mine started doing same thing, thus I pulled injector and throughly cleaned and blew it out, runs fine again. I’d suggest putting a new one in. They come with cheapo’s from China, but that’s not saying new ones are built there too but they are cheap in price. Check fuel pump assembly to make sure it has a filter to catch garbage being sucked up from gas tank. Should correct your problems. I’ve learned a lot about mine lately but it still runs great with a little maintenance!!

I just started narrowing things down as suggested by many, electrical, air, fuel filters, fuel pump, oxygen sensor, then injector was last and it turned out to be culprit. Had white plastic shavings in it and was clogging the fuel flow and spray. It only had one injector! Hope this helps everyone!

Actually some on here gave me clues, plus internet helped out too!

Yes, it's such a shame. People who own one, really seem to like these things. And it is a good looking, good sized, adequately powered little buggy. There's good dealer distribution infrastructure already in place, to buy these things. Really, if you think about all the logistics, of bringing something like this to market. All the hard part is mostly already in place. The only thing missing is service after the sale. If this company ever beefed up a parts, and service division. They'd have a serious contender for all the other brands to contend with. Mostly because of price point.

We'll be here to help, any way we can. I wish that everyone would remember that all the information that's shared here with us, is a permanent record that others can search. To better, and more easily solve the same problem. So thanks for sharing any new developments. Good luck!

Just to update everything, got my Hisun running again,  bad injector.  These machines are now know for such issue. Put in new injector (compatiable, better built one) & it runs better than new! Thanks for everyone’s help here. Hopefully it’ll help others with same issues!

If it's an OBD2 port, then, in theory it should be easy to connect. I'm sure that it won't have all the pids that an auto has. But if it has a compatible protocol, it should give up what it does have. A live data reading would solve the problem in short order.

The OBD2 port has a distinctive shape, as do all the different diagnostic ports. The tester is cheap enough. I buy the cheap ones at harbor freight. Make the shape comparison, to be sure it's actually the right port. Non OBD2 is a bit more difficult, because it's not universal. So there's no point wasting time on that.

That belt sensor is probably hard wired then. I've got the same thing in my car. Short of unraveling the harness. Only an electrical diagram would tell where it goes. Even then, it likely goes through the CPU. 

Nothing much to add, unless you haven't tried jiggling the buckle while it's clasped and driving. Listening for any change in engine tone, or cadence. 

So waiting on the service tech would be my move. Otherwise you're chasing things that likely aren't broken. Which isn't necessarily a bad thing, if you had the tools, and the time. Ask the tech, if you get the chance. If it is indeed standard OBD2. This information will come up later! 

Now would be an excellent time to source a service manual. If it's even available now, it certainly won't be in a couple of years. 

 

 

Thanks Ken, yeah I’m gonna wait on tech to give me an appropriate answer but he said he had to go thru the channels with a Hisun tech because he doesn’t even know himself. Hisun needs to educate their service reps and service what they sell. It’s common practice everywhere else. This is a good running machine WHEN it’s runs!!!! I will let everyone here know when issue is diagnosis and cure is found so that others won’t go thru so much red tape for a fix!

The book shows trouble codes so I’m assuming a plug I found in front by storage compartment & radiator is my OBD2 port. To trace this wire will result in complete wiring breakdown as it’s involves other circuit wiring  in the harness itself. I did use jump wire on seatbelt also checked voltage thru it. It test low voltage thus I jumped with no different results.  Appreciate  the info bro.

It’s s  the same issue I had last yr, wasn’t a clogged injector.
