Code problems -p1211 and p0603
I have a 2002 F250 7.3L 4x4. I just rebuilt my HPOP, Fuel Bowl, and High pressure lines. After that was done my engine light came on. It showed these two codes p1211 and P0603. 1211 reads injector pressure above desired pressure. P0603 reads Keep alive memory . I have replaced the ICP. The IPR and the pigtails on them both also.
I am asking for help to tell me how to get rid of the codes and how to repair the problem.
Thank you for your help in this matter.
