While the actual codes may have helped, I'll give it a shot.
1. The PCM uses a compareative value from the Map and Mass sensors to determine its fuel strategy. One of them is way out range or is unplugged. Check the plugins, I figure a plugged air filter or a massive air leak,
Air filter not seated correctly, filter sentenal not plugged into the houseing, something of that nature.
2. The A circuit of most sensors is the power circuit check the wireing to the turbo circuit.
3.Check the harness plugin at the FICM is fully seated on the first plug, and snapped in.. This is the PCM to FICM circuits. The injector harnesses are the next 2 plugs. One for each bank. Check them as well.
4.Check plug in for #5 injector. Since ya were moveing the harnesses aroung it may have pulled loose.
5. Five and 6 are related check EGR circuit wireing for short/open chafes etc.
Just a few things to check
