P0232 code help

[ian.jones5557]

First off I'd like to say hello to everyone. New to the group. I have a 08 with 135k on the clock. The truck is completely stock. 2 days ago the battery terminal corroded and split in half. I replaced the terminal and I immediately started having hard starts and cruse control not working. I will have a wrench occasionally and when I have the wrench I think I am in limp mode.

Had the codes pulled today and I got a P0232 (fuel pump secondary circuit high), C1145, and C1234.

What causes the P0232? Could it be the injector pump failing? Any help will be appreciated.
