i have the same problem man, im on a 1012

 

havent changed anything since the day the car was tuned. it ran great for a month then developed this problem. i tryed putting a big ass boat battery and still had the problem. iv heard main relay? and yea maybe the starter? i emailed aem and they said this doesnt sound like an ecu problem. the ecu problem was, it would cran normally and just not start. mine cranks very slow when hot. thanks for the help guys. i guess ill try finding someone with an s2k to swap relays with first, if not ill try the starter $$$

 

Let me know, I'm gonna send my aem in
