I am Scott and I will assist you with your vehicle concern.
I am sure having worked on on vehicles, you have the information from KIA or Motor/Alldata, ect: The one thing that is VERY important on this motor is the belt deflection and the cam marks.
IN THIS ORDER ONLY "Align the timing marks of each sprocket and install the timing belt in this order. Crankshaft sprocket → Idler pulley → Exhaust camshaft sprocket (LH) → Intake camshaft sprocket (LH) → Water pump pulley → Intake camshaft sprocket (RH) → Exhauft camshaft sprocket (RH) →Tensioner pulley"
Now if you are hearing a click, and have resistance, I would bit start the engine yet. I would do a cylinder leak down test first. I fear, that somewhere a valve kissed a piston.
The firewall cam shafts tend to have more spring tension and may spring back. I have had instances with clients having a cam spring back when removing the belt and actually, inadvertently bent a valve if returning it counter clockwise.
Play it safe, do the leak down test and if it passes, get a belt from KIA. It comes with the reference marks that carguy had mentioned, and takes the guess work out on the beck cam sprockets.
