P500 2020 500 with CEL

[buford1983]

2020 Honda 500 has a check engine light, Neutral flashes with CEL flashes. It just came back from 20hr maintenance and ran good. I thought it was bad fuel so I siphoned it out and put fresh fuel in. It barely starts, barely idles and dies when I hit the gas pedal. Any ideas? I'm new to the UTV world

Just went through my second bout of water in the gas. Wouldn't start, but everything else seemed normal (no lights or weirdness on the display). Pulled a couple gallons of gas out, got it going but rough, finally started running normally again. Don't know what gremlins you've got, but good luck.

Coolant temp sensor indicator is on too so that may be it

Is there a pattern with the CEL? If its the CTS, the fan will run anytime the key is on.
