just got my s2 couple months ago was a track before and it was always a summer car for previous owner and Its my daily driver and yesterday I left it outside all day it was freezing and car was fine before when I was driving, so when I came back and tried to start it wouldn't turn over and I heard a loud pop like a gun shot the third time I tried to start it. And maybe once or twice it sounded like was about to start but just wouldn't stay on when I gave it gas New to this forum any help would be appreciated.

Today I went to a mechanic And he said there's no response from the cam and crank sensor whatever the hell that means I'm not that mechanically inclined clearly and he told me to take it to somewhere that specializes in s2 because of the kpro he says he can't do anything
Any suggestions?

 

Mods are kpro I/h/e thanks

 

Check cam positioning sensor. Car will not turn on without it in working order. Will also make the car backfire.

 

At least try and clean the connectors then try and start the car. The cam positioning sensor is located on the back side of the valve cover.
