2000 chevy Impala LS - Code P0440

I have a 2000 Impala LS, 3.8 ltr. I have a P0440 code showing. On May 14, 2008, I could not put gas in my car . The shop scanned it and the same code came up. They replaced the EVAP solinoid and all was fine till May 25, 2008. I bought a code reader and its the same code. I cleared the code and removed and reinstalled the gas cap. Anyone have any other suggestions? Thanks.

There's more P0440 tips here - http://www.obd-codes.com/p0440

did the replace purge solenoid under the hood or the one valve back by the tank?

I had the 1 near the tank replaced. Should the 1 under the hood be done as well?

I tightened the gas cap and reset the code hoping it was that easy. No go. engine light came on this morning. Now I'm a wrench turner only and venturing to the unknown for me. I did a freeze frame and this is what came up.

I bought a new gas cap and ordered the solenoid under the hood as well. Any other suggestions if this don't work?

Also check for loosen, clugged or broken EVAP hoses near the tank and near the engine.

Update - its been 3 weeks, replaced the purge solinoid under the hood and replaced the gas cap - cost around $35 - all is good - no more code.
