car: ae86

engine: beams 3sge running with adaptronic




ive got a pretty weird problem with my motor

ive just got it running and cant get it to start a twice


the story goes like this:
if i start the car with a fully charged battery it will start up first pop and run. now if you try to start the car again it will not start! all it does is backfire out the throttles. now if you swap the battery it will start up fine? ive tryed disconnecting the battery and hooking up it back up and wont start with that same battery!

whats going on? has anyone ever heard of this?
