System has 4.9 v running to evap selinoid valve but not actuating. I tested it and it functions only when I use 9+volts so I bought a new one but still not opening.
I'm lost, any direction would be appreciated.

I tried clearing the code by disconnecting neg lead on Bart but still there.

How are you testing for voltage? Check from a known good ground like the battery negative post, or engine block.
