despite what the guy at the autoparts store said, its either the battery, or battery connections.

 

i dont know it has to be today it acted like nothing happened wieeeerd

 

original battery?

 

Original battery is known to suck ***, so I'm guessing that's your problem. Easiest way to check is that when you start it you'll hear like a ticking noise coming from the battery meaning it's dead.

Also maybe your ECU could've randomly gone out.
