Does this issue only happen after you fill with fuel? How do you get the vehicle started? Do you have to wait for a while? If so it sounds like you have raw fuel in the charcoal canister and the purge is stuck open.
Basically what happens is when you fill the fuel tank it pushes vapor into the canister. When you top off the fuel tank or leave the engine running while filling the tank it can push raw fuel into the canister. Once this happens it breaks down the charcoal and gets stuck in the purge solenoid.
I would suggest removing the purge and the canister to inspect for black dust or residue in the solenoid and raw fuel in the canister.
Let me know what you find and we can go from there. Thanks
