Check and double check all your grounds, even if they look good take them off clean them then reinstall. Really you could probably benifit from a full battery cable and ground replacement.

Then you need to start troubleshooting the injector harness. Get a multimeter if you dont have one set it to continuity mode and start shooting wires between the injector connections to the PCM, you may need to wiggle parts of the harness while doing this to see if you can replicate a wire break.

Those codes are specifically related to the injector circuit so nothing on the ignition side should be an issue.
