Possibly not sure why it went flat

Thanks for your input mate but what do u exactly mean by make sure the ECU is in the right mode? Also check the ground leads off the battery?

Hi guys, I was wondering if my ecu is stuffed. Well I have a stock r33 skyline, the other night i had to jump start it cause battery was flat so i got standard jumper leeds and started it. What i noticed soon after is my cars idling is all over the place and almost going to stall and the abs, hicas and battary lights all light up now. What yous think?
