MCX Apex not starting in the cold

[BOOST]

Got an 07 MCX Apex and all of the sudden it wont start when its outside and it's like 10-20 below. Drag it in the shop and when it warms up starts right up. When its out in the cold it cranks over fast but wont fire once. Once i get it running it restarts just fine and runs great. Anyone got any ideas? Muchly appreciated. Mike

Sounds like a sensor. Last year I had to change atmospheric temp sensor and that fixed my issue. Mine was doing exactly the same as yours.

it hasnt thrown the code for it yet. i already changed the barametric pressure sensor this year. its really weird the way it wont fire. i just swapped out the plugs, which im sure isnt the problem but it was suggested. goes like a raped ape when its running, and restarts fine when its been running. thanks for now

what type of fuel are you running? If its c-16 they wont start in the cold, just remove your air filter and put a little reg in there it will fire rite up.

just running premium, and a gallon of race in each tank. only running 10-12 lbs. boost.
