Strange Starting Problem
So over the past week or so my car at times has had trouble starting. I'll turn the key and it will just click, start to turn over but couldn't crank. Nonetheless it would eventually start...this problem had gradually worsened in the past week to the point where I've become less confident that it would start. Finally today when leaving the grocery store the car wouldn't start. Just clicks. It sounded a few times like it would almost want to start but wouldn't fully crank. Tried to jump-start it to no-avail. The dummy light never came on as it had for the alternator when that died so I'm assuming its not that. Could the battery be completely shot? Starter possibly? Could it be something more in depth?
(Lights/radio etc. turn on)
