Hello all, any help would be greatly appreciated. I recently purchased a 2004 Pt Cruiser Turbo and it has been running fine in my opinion up to this point up until a couple of hours ago when it decided to not start. To my knowledge nothing was left on in the car to kill the battery and the lights and stuff all turn on when I move the key into the ON position but the second I attempt to turn it over it instantly loses everything. The lights would come back every few minutes of it just sitting there though. I have done the key thing to try and pull any engine codes but it just says "done" whenever I do it. Also in the ON position, the oil pressure sensor dash light never turns off as well as the engine light and I noticed the engine light would blink three times after being on for a few seconds. Does this sound like a battery issure or something else? Any replies are appreciated!
