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.
you have to do the gm drive cycle and also it wont test the systems if you have a cooler thermostat installed. here ya go...

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