Will try to explain the most as possible.
Car won't start. Usually, when I put the key in, I hear some kind of a click sound. I don't hear it
When I turn the key, all the lights go on, the needle for speed flickers a little but I don't seem to hear the engine running. I only hear some electronic sound.
All the electronic seem to be working fine (headlights, fan, radio). On my old car, when I had battery trouble, usually power would be weak but now the power in the car seems fine.
