Can you locate the tapping sound? Did any dash lights come on before it lost power? Is spark getting to the plugs?

The tapping sound is coming from a box at the top of the engine on the passenger side not sure what it is. No dash lights came on it just died and I don't know if there is a spark getting to the plugs or how to check that.

I'm looking at a few pictures of the engine compartment of this year Sonata and I'm not seeing any boxes. Can you upload a picture of where the sound is emanating?

Disconnect one of the plugs wires by grasping it near the base of the plug and twisting while pulling. Next, if you have a #2 Phillips screwdriver, insert it into the plug boot until it makes contact with the electrode at the bottom of the boot. Hold the screwdriver in the boot 1/4 inch from a good ground and have someone crank the engine. You should see and hear a strong and bright blue or white spark. If not, Use a meter to see if the coil is getting power.

Check out the images for the ignition circuit troubleshooting steps.
