Car works great, all of a sudden it won’t go. Everything is not working, ie windows, radio etc. Give it a jump. Perfect. I took the cables off immediately after it started. Turned the car off and it started right back up again. Worked again for days. It is completely sporadic. Already replaced battery.

So when you say it wont start do you mean it wont run or the starter is not working? Please let us know.
