Question 550 EPI Sports,man

2012 Sportsman 550 EPI
Rode Hatfield & McCoy this past week (dusty, muddy conditions)

Now she doesn't start. It will turn over and I have spark but it wont fire. (replaced air filter, and new plug as well)

Should I check all sensors? I pulled the TMAp sensor and cleaned it ... nothing. Do I check and clean connections? Can I use WD40 to clean connections with? Please Help!

:hmmm:
