So a follow up and my fix.
I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working. It showed an spec number towards the lower end of the rang, but in spec. Then while it was running opened the gas cap and the pressure should change. It didn't change even a tiny bit. The data for the purge valve said it was open...never changed.
So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be. So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in. It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work.
So fuel tank pressure sensor in I cleared the code, and started it up. I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit. So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed. Drove it to and from work for roughly a week plugged in the scan tool no codes. I took it in to get tested and passed. In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29.
