Assuming that you have all of these sensors and emission systems in place the only thing you can do is to drive the car. The PCM has to see a certain set of conditions to run these monitors and without driving it they won't run. There are drive cycles that you can perform but usually driving the car a bit will run them without issues.

All you can do is drive it.
some cars only take a few miles, and some take a lot of driving,

If they were improperly disabled through tuning they will never set ready.... just a possibility

You should hear the mechanics from New York City cry about trying to complete the GM drive cycle. They can't finish the drive cycle before they run into a traffic jam.
