Coleman 400 UTV won t start

[Kpw]

My Coleman 400 UTV is about a yr old  started it up yesterday parked it outside..later on the day it would not start. Has gas, cranking trying to start but won`t turn over. looked at trouble shooting tips and it said check spark plug. Where is the sparkplug located and any other suggestions

You say cranking but won't turn over? Do you mean it won't fire, or it won't crank?

First check your battery voltage is about 12.5V, make sure you have fuel in the tank.

From there you can check for spark the spark plug is on the back of the motor under the bed. Connect an inline spark tester and make sure you have spark when cranking.

Then I would remove the fuel injector and verify fuel pulses when cranking.

If all that's good I would check the valve lash & timing.

I just purchased a 2021 Coleman UT400 and had a similar problem. Now the manual states the grade should not be more than 15%. The hill on my property, and there is multiple ones, is probably around 35%, but I got it to get to the top, about 30 +/- feet or so. I did read in the manual that when going up hill, to put the UTV into 4WD for better traction. I have to try that to see if by having both axles pulling, the UTV will not struggle as much.

Information on climbing hills in my manual is on page 7-10.

I'll update, but give it a try and see if it helps.
