7.3 running on one bank

Ive got a 97 f250 7.3 and I am only running on my drivers side bank. Ive done uvch new pcm and idm checked the wiring from the idm to each injector and changed all 8 injectors. I ran a buzz test and all 8 injectors buzzed and I got a p1661 p0113 p0603 and a p1668 codes. Where should I look next to find my issue.

Here are the pinpoint tests for P1661 and P1668. If you have wiring diagrams you figure out what they are trying to accomplish by doing them (and you can at least look in those areas for problems). Cheers!
