Question about 2004 Kia Optima
Check the crank position sensor.
Also make sure the belt tensioner is in good shape(its hydraulic) Also there is a circular metal plate behind crank sensor that needs to be clean and not cracked/dammaged. check these items and let me know if it fixes.
The timing also has to be perfect or you will have issues. there are timing marks on the belt pulleys
