emission system on 1997 Hyundai Sonata

When I turn the key to start the car it will only click. Then one day it will start. I have changed the fuses, battery and still does same thing. Went to Autozone and had it check Code PO443 came back, Purge/vent solenoid circuit condition.
Purge or vent solenoids defective, where do I find these thing. and can they to repaired or replaced.

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.
