Hello All,

New member here, thanks in advance for the help, I hope I can return the favor in the future!

My wife and I recently bought of 2021 CForce 500S (Brand New from a Dealer) in April 2022, currently with 103.7 miles on it and used mildly on a Homestead....well, it won't start. I am done a fair amount of research, some of which on this site. When we first got the ATV when you turned the Key to Ignition, you could hear (what I assume) was the Fuel Pimp Priming. As time went on this happened more or less randomly; though, the ATV still started. Then it only started after the 'Priming Sound' happened, which may have taken a few Key Turns (On/Off) to get working...not the end of the world. Now, no matter what we do the 'Priming Sound' doesn't happen and the ATV won't start.

I have tried checking all the Fuses and Relays, no Fuse are blown that I can see and the Relays all 'Click' as expected....also checked with a Multimeter. I used some Starting Fluid (yes I know, bad idea for new engines) and got it started...sometimes. First it would only burn off the fluid and die again, then I got it to Start with the Fluid and continue to run...perfect! Sometimes after reseating all the Fuses it starts again, like new...still no 'Priming Sound'...then drives for 100 yards and just dies.

The last time I got it started with Starting Fluid, Reseated the Fuses, and Boom...worked and stayed working. Drove it for about 200 yards, let it run idle for 10 minutes, then bumped the Fuse Box putting the Hood on and it died. Haven't been able to get it started since and don't want to continue trying more Starting Fluid. Seems to be a Short on the Fuse Box Connection and/or something with the Fuel Pump.

Called the Dealer and basically was told to 'Pound Sand' and/or have a 4+ week delay before they will even LOOK at it, starting after I drop it off. Can anyone help?

Thanks!

Welcome. First I would report this dealer to CFMoto. Next, if there are no other places to take it, fuel pumps don't run because of very few reasons. The main reasons are- One-the pump or pressure switch is going bad, Two-the ignition or the kill switch is failing, Three- the AUX relay is failing..although if you have spark to run it with starting fluid it probably isn't that. If it has it might also check the roll-over sensor.
