TIMING MARKS ON VALVE CAMS AND TIMING

My car is a four cylinder, two wheel drive, manual transmission with 194,000 miles.
Having camshaft on TDC, please help me align timing belt sprocket (two marks on this, which one do I align to front of engine--there is a hole in the sprocket, should it be at 6 o'clock?), And where should the valve cam marks be?

Okay, here is what I was able to find on the belt and chain timing marks and alignment. If there is more needed please just ask I will look for more. Thanks and hope this helps.

With reference to your drawing for the engine timing marks above, I had this same problem with understanding these marks. I replaced the head gasket in my engine without pulling the engine out of the car and have everything put back together but cannot get my car to run. My car is a 96 Elantra 1.8 but these markings appear to be the same.

Do the cam shaft markings have to be lined up with the cam chain markings when the timing belt cam shaft pulley is at TDC? My crankshaft markes lines up with the chain marks but not when the crankshaft timing pulley is at TDC. Is that normal?

The other thing I need to know is this. Since I didn't have an engine hoist and didn't pull the engine, the motor mount on the passenger's side is in the way. I cannot remove the crank shaft pulley or the lower timing belt cover. Ive been using the mark on the crankshaft pulley to line up with the zero degree mark on the plastic TDC indicator on the lower timing belt cover. Is this acceptable for lining up the crank shaft at TDC?

I don't know what I'm doing wrong but if my timing marks are lined up right I can at least eliminate that as my problem. Thanks for your help!
