    Check the wiring again and see if fuel pump relay is seated correctly. It's located under the driver's side dash. You will need to remove the lower part of the driver's side console to reach it.

    Check the heavy-duty fuses on top of the battery and check fusebox also.

    Oh, it also seems that your MAF is on it's way out from 16486 error and your pre-cat lambda sensor had better days by the looks of things... Although, I'm not sure if these can be caused by related electrical issues with injectors.
