Looking for input/tips. Thinking ill try replacing the gas cap first. Sorry for bein very short. I'm just overly frustrated with the situation I'm in

Re: p1440 question
Welcome to NICO!
There are many possible causes for P1440. It is best to start by replacing the gas cap with a new OEM one. If that does not resolve the code, try following the diagnosis procedure that is described on page EC-400 of the factory service manual from step 8 and onward as best as you can.

thanks. Tried the gas cap. Light is still on. I'll take a look at the link you posted
Re: p1440 question
trying to make heads or tails of that manual. Canister and purge valve seem ok. As far as I can tell the hoses are ok too. Haven't tried smoke test or use the leak detector shown in the Manuel
