Hi,
When you replaced the pump, was it only the pump or was the module replaced which contains the pump?
I ask because there is a vent valve before the charcoal canister which is part of the module. If the only the pump was replaced, there could be a blockage.
I attached the diagnostics below for the code you have. (Pics 1 and 2). Pic 3 is the one I feel is of most interest. Make sure the vent tube that is attached to the filler tube isn't damaged and where it connects isn't bent, preventing airflow.
Also, I highlighted from the fuel tank to that tube. Check for restrictions there.
Let me know if this helps or if you have other questions.
Take care,
Joe
