Hello Everyone
I posted my problem back in the spring sadly i was unable to find a solution, so put the atv away for the winter but with spring here now I'm hoping to get this issue fixed and to get out riding.

I have a 2014 800 terralander, I bought it used and unfortunately it never really worked well it was always running rich and fouling plugs. i found that the previous owner had way too much oil in it, well above the dip stick line. so the atv was running I parked it then 2 days later I removed about 20 oz of oil from the engine so that it was about 3/4 the way up the dip stick. That was all I did and when I tried to start the atv the starter would turn over but I had no spark and my fuel pump wouldn't engage to prime the line. I have tested the kill switch contacts, and i have tested the fuses and swapped relays without any success.

Need to test the power at the pump and coils with the key on. If none, need to work your way back. If there is power and neither won't run then check the grounds. The main ground is on the engine case and chassis ground is with it. The systems ground will be to the frame...somewhere and the manual may help find that.

Now my rad fan isn't coming on and my temp isn't registering. The fan does work when I connect 12 volts to it. Would the CTS be the problem? I was thinking the thermal switch on the rad but the CTS is what registers the temp correct?

CTS?

Coolant temperature sensor which I believe is around the bottom of the cylinder kind of above the water pump.

Oh...then no, the fan switch or thermoswitch is on the radiator. That's the one that's known to fail so much...but it only provides a ground for the fan relay, nothing for the temp gauge. That is straight to the.. CTS.
