My car wouldn't start or turn on at all. So I installed a brand new battery into my Lexus Lx570 and it started well the first time. Second time I come to start it, it does not start. Only the dashboard lights come on, and also the remote works as well. However, I hear no clicks, no sound. The engine just wont run at or start at all. I tried replacing the starter relay with another like it, but that didn't work either. The battery is set up right and tight. The terminals are not loose.
