So I have a 2001deville dts and have been chasing the p0440code for a while now. Had smoke test done twice by firestone and replacement of evap canister, purge valve, solenoids, gas caps, fuel pumps w/new gasket, fuel pressure sender. So I go to the junkyard to pull a fuel filler neck of a 05 deville and see that its plastic? The p0440 is holding up my state inspection so going to swap the filler pipes now and see what happens...:confused:

Well if it's plastic it clearly isn't rusted out, unless the '01 used a steel one.

This place is very clearly just throwing parts at it (or having you do so).

You might check that the green plastic cap is in place on the EVAP test port in the engine compartment.

Sounds like you've covered all the bases.
Have you checked for a clogged or ripped, cut or chaffed vacuum line?
