You used foil tape like used on air ducts ? Then wrap all three wires with tape or something to hold them together?

@hap9915 9 ай бұрын
Sir.. great video. Thanks for taking the time to explain in detail, but not overtalkin. I have a 2016. Hard start... Unless I use starting fluid. After it warms up, it starts perfectly every time. Sometimes if I crank and and crank the CPS code will come up. . But if I just spray starter fluid, whike cold, and start it up, no CPS code. Runs fine. A lot of videos mention adjusting valves, if it starts up once warm. Any thoughts from a guy who has dealt with these?
@performance406 6 ай бұрын
Could be valves, but if they are that far out you'd probably be able to hear the rattle well when cold, not only that, as your valvetrain ages you usually get tighter tolerances as the valves wear into the head, not looser, and the symptoms would say the tolerances are so far out when cold it starts hard, but after warm up and expansion they are close enough to aid in starting OK again. Could also be fuel injectors, fuel pump, or even spark plugs. I' would still lean towards a bad wire somewhere , these have terrible harnesses. Start with the cheapest stuff first. Good Luck!

Thanks for your video. I'm chasing this issue myself. My issue is it starts find some days, but if it has rained or high humidity it will not. And I keep it in a building so it's not out in the rain. So far, I've changed the sensor no change. So I changed the fuel pump and it started and kicked off quicker even. But I had checked the pressure is it was ok, but I did the pump anyway. Worked for a week then it rained again. So it's not starting again. I've got new plugs and they are sparking. Of course I don't know if the are at the correct time or hot enough. I've started to work on the wiring and I'm not very comfortable with that. I started at the sensor and see a bare wire there. But it goes into insulation down by the plug and looks like there is a broken strand or two there. So wondering if it is probably that before going further into the wiring.

@performance406 3 жыл бұрын
@@johngould2288 You could go a hundred different ways on this. Really depends on budget and applications. For shocks, I usually recommend Fox. They offer some really good budget shocks, but the higher end , like the 2.0 RC Race shocks are really good, for higher speed control and dampening. If you want tuned shocks to your specific wants I strongly recommend Shock Therapy. www.shocktherapyst.com. Shoot them a message. As for exhaust I lean towards Big Gun, believe it or not, however, unless you are going very high performance just about any exhaust on the market will be suitable. My 2 cents. hope this helps, and have fun with the build. Check out all that wiring! Polaris builds a good machine, just wish they put a little more quality into the wiring. Hope this helps

Hey man I’ve got a 2016 900xp ranger and I’m having issues with it cranking. It started out back a few months ago I got it out one day and it took me like 3 times of turning it over for it to crank and it kept doing that all throughout the day that day. The next weekend it wouldn’t crank at all. So since then I’ve replaced fuel pump, new spark plugs, and ignition coil. Currently waiting on fuel regulator to get here. But I’m not sure what to do next, it turns over strong, but just not firing. I have no codes or anything. Any feedback would be awesome!

Having the same issue. But mine has shown CHK ENG code of 0 636 2 (CPS code). Started fine all this time, but we've had really cold weather and I didn't start it for a few days. Now just cranks and cranks and cranks. I'm assuming maybe bad gas although it's fairly fresh. Or something frozen or stuck? Let me know what you find out on yours.

Have a 2016 xp4 1k and it is having a tough time. Will crank and crank but wont start unless i jiggle the wires just right. How far back up the harness have you seen a bad wire. I replaced the sensor and the connector and still have same issue. once i get it to start it runs perfect. Is there another sensor in that part of the harness that could cause this. The TMAP, Speed sensor, Shifter sensor, and whatever sensor in exhaust are all in the same harness at the rear of the machine.

I'll bet you it's a broken wire in the harness very similar to the video. The one in the video was the farthest one I've ever seen it was almost at the seat. They can be a real pain. Look for a twisted wire like the video. Good luck.

Yes, Very good chance of it, most complaints I've seen start with the warm engine comment. Could also be your stator or fuel pump, but probably not in my opinion. When things warm up they expand, if you have bad connection or wiring it can cause it to separate more and quit working. Usually why you see stators failing whenever only when engines warm up. Thanks, Hope this helps.

I have a 2013 rzr 800s that is throwing the same code. Starts fine cold, runs fr 15-20 till it gets hot then sputters and dies. Wont start again till cooled off. How would heat play a factor with a kinked or unprotected wire?
@performance406 4 жыл бұрын
In that situation you might just want to start with the actual sensor any electronics as they warm up expand from the heat. This will in turn caused them to stop working if there are any broken or loose connections inside the sensor or on a circuit board. However this machine that is in this very video had those exact same symptoms. if it's a seven-year-old Polaris, you better dig into that wire harness in my opinion and look for any kinks or rubbed through wires. Thanks. I hope this helps. Good luck
