The "clicking sound" when you try to start the car is either due to low battery voltage (bad battery, battery draw when car is turned off or charging system issue), a voltage drop (due to bad electrical connections) or most likely a bad starter motor/starter solenoid
Purge control solenoid is located in the center rear of the engine compartment on the firewall. Hyundai as a car manufacturer put a lot of free technical information and workshop manuals on line for Hyundai owners. Check out www.hmaservice.com lots of great information.
