So im getting P1223 (injector 1 output circuit) and P1241 (injector 7 output circuit) also P0089 which I thought odd because my LBZ FPR is only a year and a half old as well as my exergy 60 overs.

Has anyone experienced this problem before? Im guessing a wire is chaffed, loose, pinched, or burnt lol. Pulled the codes at dusk and ran out of light. A fellow member here instructed me to wiggle the harness going into the FICM while the motor was running but could not make the symptom active by doing that. Any advice on where to go from here? Maybe the wires connecting to the injector/s are loose? Bad harness alltogether? Thanks in advance!

Unhook the ECM connectors. Blow them out with air and let them dry for ~60 minutes before you reconnect them.

I could be wrong, but I think all three run off the same +12 source. I know those two injectors are off the same source.
