Answer 1

Some tests need to be done to determine exactly what the problem is, but based on the P025A code and the symptoms, the most likely cause of the problem is the Fuel Pump Control Module (FPCM). The P0171 and P0174 codes are set when there is a lack of fuel, which is caused when the FPCM fails. You could start by checking the FPCM, making sure the FPCM connector is secure, and there is no corrosion. The module is located above the spare tire.
