Hey there!
P025A and U0109 trouble codes can be a bit of a pain, but we can tackle this. The P025A is related to the fuel pump control module, and U0109 is a communication issue with the Fuel System Control Module. These codes are covered in depth in our company's articles. Click here for P025A and this link for U0109.
Since you've already replaced the fuel pump, it's a good start. Now, I'd recommend checking the wiring and connections around the fuel pump and the fuel system control module. Make sure everything is snug and in good shape.
Next, scan for any loose or damaged wires and connectors. Sometimes, a simple loose connection can trigger these codes. Also, check your fuses – a blown fuse can lead to communication problems.
Use a multimeter to test the voltage and resistance at the fuel pump connector. If the voltage and resistance are within specifications, then the problem is likely with the fuel pump control module.
If you have determined that the fuel pump control module is faulty, you will need to replace it. You can purchase a new fuel pump control module.
Once you have replaced the fuel pump control module, you will need to clear the trouble codes from your vehicle's computer. You can do this using a scanner or by disconnecting the negative battery cable for 30 minutes.
If you are still getting the P025a and U0109 codes after replacing the fuel pump control module, then the problem is likely with the wiring harness. You will need to repair or replace the wiring harness to fix the problem.

We hope this information is helpful. Good luck!
