2018 Textron Stampede 4 Engine quit and will not start.


Recommended Posts

What a wonderful service manual--I need to send it to Hisun and Coleman so they can see what one is supposed to look like!

In reviewing the wiring diagrams I see that he injectors, Lambda (O₂) sensor and ignition coils share a common power feed from terminal C6 on the main harness (this is good news as it links directly to the DTCs):

On the wiring harness it looks like this--with SP1 (SP=splice???) being a common connection point:

They also provide this splendid illustration of where all this stuff is located (though the O₂ sensor does not seem to be shown)

Before hauling it 100 miles check that main harness connector, and the  connectors at he injectors and coils  to make certain they're not corroded or otherwise fouled. Check all ground connections as well--check the O₂ senor connector as well as it is quite possibly located is a place that can collect all sorts of crap.

Also, the usual suspects, battery connections, voltage

 While cranking [at the terminals, not he battery posts], , etc. It may be coincidence that all three reported "low voltage" at the same time but I'd look for a common wiring problem.

Cliff, thank you so very much for taking the time to show me some possibilities that could be the cause my issue.  I will do my best to sort it out with your most welcome help. I have checked the main grounds and connections to frame grounding and they are all tight and seem to be in good condition.  I will certainly take your advice and do my best to check things out.  Thanks again Cliff, I really appreciate your help!

You are quite welcome--let out a yell if you have any questions, or just want to bounce around some ideas. I don't believe the O₂ sensor issue would prevent the engine from starting.  Try unplugging it, if it's heater is drawing too much power and dragging that circuit down disconnecting it "might" allow the engine to start--worth a try, if it starts you know which part to buy...

Thank you for another most welcome suggestion Cliff.  I hope to check all of your suggestions this weekend.  I have looked around the engine compartment and it is pretty tight with all wiring covered, so I hope I can find the connections........ I will post what I find or cannot find.  Thanks again for taking time to help me out...

Hello Cliff, I wanted to say thanks again for taking time to help me out.  I had to take it to a local ATV shop and hope for the best.  They figured it out!  It was a bad cam sensor and it caused several other codes to be displayed as well.  The common error was the cam sensor.  I ordered one through Country Cat (a great source for many makes and they are helpful as well) and had the part it 2 days and all is good for now....  Thanks again Cliff .   Paul

      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!

      ATV just clicks when trying to start. Battery is good, has a new starter, and all the wiring looks good. any suggestions on where to go from here? thanks

      My "R" light on the dash will not go out when I take the UTV out of reverse and put it into any other gear. Is this just the light switch issue or will this effect engine performance in the other gears?

      We just bought a used 2017 American Landmaster TW450. No hour meter that I can find, so not sure exactly how much it has been used. 
      The first 2 days we had it, the starter was a little sketchy, but it started after 2-3 tries. Sometimes when turning the key, we would hear a loud metal "clink" sound. Like the starter made contact, but didn't have enough power to turn. 
      THIS MORNING... Turning the key, we hear a single click sound. That's it. Even with a new battery, the starter is still doing the same thing. Both batteries (old and new) were reading 12.8 volts on volt meter. So I'm wondering what else could be going on? Any ideas on what to look for would be greatly appreciated...
      Thank you!

      Spent today at a Honda dealership looking at their 520 side by side, then on the way home past our Lowes noticed they had several new UTVs on site, so we U-turned and ducked in there. We were impressed that all that came for $9,999 metal whole length skid plate, nice sized bed, roof, windshield, side mirrors, winch, upgrade looking tires… all of which would have added thousands of dollars to an already expensive Honda 520. Now Honda does have a great reputation from my trusted UTV experienced buddy, so it has that going for it.
