You said you already replaced the gas cap. Did you buy a new or used one? For the cost, I would try another cap before going any further and make sure the one you get (or the one you have) is properly and completely sealing the fuel system.

I purchased a new cap with a key from AutoZone

When I installed it the cel went away for a week but came back

To really know it should be a Volvo fuel cap not a generic from Autozone or some other aftermarket supplier. Many of these aftermarket caps do not seal that well.

check lines going from gas pipe to evap canister. there is a J hose that usually breaks. jack up vehicle on drivers side and go under car and you will see evap canister. looks like a box. then also follow those lines up to the engine. they are plastic and go to another small hose, which also usually cracks. I had same issues with my 98 Volvo s90.
