Have you checked for ign voltage on the pink wire at the purge solenoid?

hi not yet i told my mech about your reply be he is thinking its the fuel sylinoid in gas tank
but to me vacuum purge would not have any thing to do with fuel tank only thing i found we have not tried yet is
check pink wire to purge valve
replace vacuume switch
or aproblem with the PCM board
what might you think?

RE: 96 corsica error code PO441
 

There is a pressure valve in the gas tank that could fail, and cause the system to not hold a vacuum, which in turn could cause that code to set
There are many things that could contribute to the code being set from a crack\broken hose, bad purge solenoid, bad vacuum switch, or the pressure valve in the tank

I think we got it fixed I was wrong I had not bought a charcoal canister we replaced it last week found 2 lines mild splits and finally replaced this GM OEM Efe System-Switch 24506192
which I think was main problem in 2008 1 day so far no light on dash im hoping in 2 more days of driving the light stays off make sure if you have a purge vacuum leak replace this switch on back of motor GM OEM Efe System-Switch 24506192 thanks for all your help
