O2 and Evap monitors remain incomplete

I am working on a 2002 Chevy S-10. Unfortunately its way overdue for emissions and in CT the registration can't be renewed until it passes. It originally had a check engine light for a secondary air issue which I diagnosed as a bad motor and a bad vacuum switching valve. I replaced both as well as all of the vacuum lines. It has been driven daily for 2 weeks since that repair and the check engine light has remained off and the monitor for the secondary air system has completed

The problem I am facing is that the monitor for the 02 and Evap still remain incomplete. It has been through several tanks of fuel and the temperature has been moderate enough that I can't see how it has not run the Evap test. It has not set any codes for these systems either.

I did hook a smoke machine to the evap system and I am not finding any leaks. I also energized the vent valve and confirmed that it seals and energized the purge valve and confirmed flow through the purge valve while open and no flow while its closed. My smoke machine is a cheap one so its possible I missed a small leak. I am just unsure why a code would not have set for this yet.

I also looked at the O2 voltage and the O2 sensor seems to be responsive. again there is no code the monitor just remains incomplete.

If anyone has any suggestions of a direction I may be able to go in I would appreciate it.

Thank you in advance.

Evap doesn't even remotely surprise me, because they can be really picky. You can probably force EVAP to run if you have access to a Tech2. It is a little odd that o2's haven't run after 2 weeks, but it's not totally uncommon either - especially if they don't have enough variances in their normal driving conditions/commute.

Print off the drive cycle/test enable criteria and give it to the customer. Explain that it doesn't matter how much they drive the vehicle, if they aren't fulfilling the requirements of what the PCM wants.

Most states allow for 1 test to be incomplete if all the others passed, IDK if that's the case in CT, but the customer may only need to get one of the 2 monitors to run.
