Q: If fuel system monitor not ready and NO codes??? on 2002 Hyundai Elantra

The emissions control system has 3 monitors that are supposed to be continuously monitored. They are the component monitor, the misfire monitor and the fuel system monitor. The PCM is monitoring and evaluating the performance and accuracy of these sub-systems 100 percent of the time. Why would my fuel system monitor be NOT READY and therefore will not pass emissions testing. There are NO codes be displayed neither hard codes or soft codes. Car runs great with no MIL codes but this system is not ready. Can anyone PLEASE help me to get thru emissions. Thank you for your time.
