Hello and thank you for your question,The common cause for these codes to set is usually due to either a failing fuel pump or a bad fuel pump driver module with the driver module being very common. Since the pump is new I would start with checking the driver module. There are known issue with the connector at the driver module becoming corroded due to its location. I have enclosed the steps in the link below for testing the driver module as well as its location . Copy and paste the links to your browser to open and view them. Post back if you have more questions and or need more help and we can work from there if need be..
