This Malibu 3.5l 2007 took a long time of various driving and still doesn't pass the evap emission test. Other tests passed since code clear.
So many codes are showing up, making me very confused. Is there any pattern to this? Is it a fuse/wiring issue or computer?
The battery voltage was 12.27v, maybe that contributed to it. But I ran the vehicle for a while. Then measured, it was 12.6v. I shut it down, then started it up before reading the code again for the ignition cycle.
Please help.

All of these codes are not set, this is the Not Run or Failed This Ignition Cycle: list which means either they did not get tested yet or failed the test during this ignition cycle (only since key on) this list will always be full when you start the car and slim down as a drive cycle is completed. As for emissions not testing did you perform drive cycle and does your fuel gauge work and is it between 1/4 and 3/4 tank of gas?
That helps alot. Thank you.
The tank initially has more than half full. After a long drive, it didn't mark the evap emission complete, so I filled it up to full. Maybe I should have waited 8 hours (that what I read somewhere), before trying again.
So it looks like I need the gas level down to less than 3/4 to test this.
The EVAP monitor will not run with a full gas tank, generally it should be between 25% and 75% to execute the test. You should check service information to get the exact numbers for your car but with the aforementioned values you should be in the ballpark
