Battery was dead, so When jump starting, I hear a fast clicking sound.

What is your question?

2016 Kia Sorento sat for 2 weeks. Battery was dead, so got jumper cables and donor car. Now have power, but pushing start button gives a fast clicking sound for 30-60 seconds. I heard you can try tapping the starter to get it to engage. But can’t find where the starter is. Where is the starter? Does it sound like the starter has gone bad?

What makes this problem better or worse?

Nothing

How long has your 2016 Kia Sorento had this problem?
