Hot start issue on the T2

Anyone have any issues with starting the T2 once it's been running for a while?

Once the engine is hot, I regularly have to turn the key twice to get it going again. Once I do that, it fires up after two or three seconds. It'll never start on the first shot if it's hot. This is nothing major, but it is annoying.

I've tried tapping the gas on the initial shot, but that was a mistake. I'm guessing the mixture is slightly rich on the hot restart because of this, but I'm not sure.

It turns over just fine both times. I'll explain what I do. I turn the key and the engine turns but doesn't start. I turn the key off for a second or two, then turn the key again. The engine starts fine after that.

I heard of this problem on some Nissans, and Nissan had found no fix - engine starts fine, but only on the second attempt. The manual does have a troubleshoot section for hot start issues, but they speak your language Kinarfi, not mine...

I think I may have the same problem, only cold starts though, but I'm old and retired and have learned that nothing really matters, so if it starts on second or third try, I go play and forget that it didn't start like my GMC that I climb into, put the key in, turn it, it starts, and away I go. I seldom if every crank for more than a second, if it hasn't started by then, I hit the pedal once and try again.

Your fuel pump may not be priming good. Maybe try to turn the key on and let the pump prime then turn the key back off before trying to start and then turn it on again and try to start onlyafter it primes a second time. The pump has a check valve in it to hold the prime pressure. If it is leaking slightly it could cause the problem.

Yeah. I found that doing what Kinarfy does with a cold start helps - pump the gas once before turning the switch. I'll try your idea.

I wouldn't have mentioned it, except that I have the only Joyner in Panama. This means everyone comes and looks, and starting trouble on a hot engine is slightly embarrassing.

Try to hold the throttle to the floor when starting it hot. It could be flooded and holding the pedal all the way down puts it into flood clear mode when starting. In flood clear mode, the computer won't inject any fuel so flooding can clear.

As Lenny mentioned to me over the weekend for every hour of riding he does he spends 8 hours working on it and modifying it. He truly enjoys it that is for sure. I am just appreciative that he shares his knowledge with all of us because it sure makes fixing our problems a helluva lot easier! We lost another contributor in Rocmoc because he sold his. He was at the Jamboree for just a few hours with his new purchase a Dune Buggy with a VW engine. That is no fun to work on compared to a Joyner and you know it Rocmoc. That is just too easy. Our Joyners are what makes us not sleep at night trying to figure out what the hell is wrong with them! You know you want to get another one after seeing us all this weekend. LOL

      2021 Hisun Axis 500 No Start - Need Help Please
      By Hunterman22
      2021 Hisun Axis 500 UTV (From Lowes)
      Will NOT START
      MY apologies if this is to much info just wanted to give yal the most information possible for help.
      I'm a so called diyer. An Electrician by trade 21yrs. I got my S×S from my last job. The contractor purchased this S×S for this specific job brand new, from Lowes. They used it for hauling materials, tools, & a little bit of anything you can think of on an Industrial type job site. 
      I remember getting on the SxS one time & pushed the gas petal all the way to the floor & SxS had very little power. 
      So anyway ,when the job finished up back mid July this year (7/2024) , I asked the contractor what they was going to do with it. I was told to take it. Otherwise it would go to the contractors yard (storage yard) & most likely rust away. 
      Took it home washed it , it had a heavy coat of dust on it & in it dust was every where. My helper & I had to push it on the trailer to get it home.  After washing it throughly I let it sit & dry out for a good day and half, maybe 2 days. Before trying to start it. NO START. Will turn over & try to start but thats it. 
      So here's what I've purchased & installed. New Air Filter, new spark plug, new air idle control valve (AICV), new throttle position sensor, new throttle body, new oxygen sensor, new digital dash speedometer/fuel gauge/clock. 
      Also drained the old oil & gas & replaced with new oil & 93oct. gas. I should probably mention that I've changed the AICV twice. The 1st time I changed the AICV I was able to get the SxS started & let idle for at least 10-15min. Drove out of the garage, with very little power,  turned it around & barely got it back in the garage.That was the one & only time I've been able to start the SxS. I've also cleaned the Throttle Body and & intake with TB cleaner.  So after that the AICV was  making weird noise so I pulled it out & tried cleaning it, pretty sure I messed it up. So I purchased a Throttle Body that came with new AICV & TPS. Still NO START.  I've checked the fuel pump & the fuel injector.  I took the injector off still hooked up to wiring & turned the key over, the injector sprayed a lot of gas out kinda the size of a volleyball. I've also checked the clearance gap on the intake & exhaust valve. But today 11/2/2024 I'm going recheck spark plug gap & the valve gaps. And alot of other checking. Would the driver side seat belt have anything to do with it not starting?? I know the driver side seat belt has to be in gauged for full throttle "going fast". Thing is the drv. side seat belt will latch but feels like might be messed up inside of it. Tired opening it up but to no avail.  I've never had a S×S or 4wheeler so I was really excited when I got the S×S,not so much anymore.  I work on & fix my own vehicles usually no problems.  But this SxS is kicking my ass.
      So if possible & someone could help me with some ideas or tell me what Im doing wrong or did wrong, I would greatly appreciate it.  Thank you for reading thus far.

      bd 300 bulldog shifting issues
      By Dennis
      I have  a bulldog i bought from home depot in 2013.  In the last season it started refusing to shift from neutral to either forward or reverse.  I changed the trans axle fluid and made sure the cables were lubricated and free.  With a lot of coaxing, I can sometimes get it to shift.  once I start driving it, things improve until I let it set awhile.   Any suggestion on where to go from here?

      Axis x550 02 sensor on right after buying the UTV.
      By TPlummer
      We recently purchased the Axis x550. Fueled it with 93 fuel and drove one time around the farm and the 02 fault error appeared. Any ideas?

      2017 Intimidator XD4 800 Check Engine
      By Reynolds Rocket
      I have a 2017 Intimidator XD4 800cc 4x4.  It will run great and then it's like it goes into safe mode and only runs on 1 cylinder.  It's not fouling out the plug when it happens.  Some times when I stop and restart it, it works fine.  First I thought it was a spark issue, then a fuel issue, but I feel like it's a short in the wiring some place.

      Bulldog BD700 Engine Swap
      By lmarkie
      I swapped out the Subaru motor for a Predator 670cc. If I remove the heat shield around the muffler, The stock muffler sits in there just fine with 1" to spare.
      Only problem is the exhaust exit is toward the back seat instead of out the back.
      Do you all think that the stock exhaust would be okay (just as effective) if cut a hole and welded a pipe on the reversed (opposite) end? Of course, plug the old exit end. Other option I thought of was to roll a tube 180° with a 7" center line radius and finish extention of 12" or so.
      Any thoughts?
