I attached the testing for this code. If you run through this I am sure you will find the issue. However, the P12A6 code will cause your issue so we need to perform each of these tests and go from there.

Clearly the vehicle is telling us with this code that the fuel pump driver is not sending a voltage signal so we need to fix that first.

Let me know what questions you have.
