Update:
I successfully connected the scanner and was able to perform a scan yesterday evening. I couldn't load the bin file for the 3.4 DOHC so I tried the scan again after loading a 3.1l bin file.
As expected it indicated that I was running rich however it also came up that my electronic spark control module was faulty, placed another one on order, just awaiting it's arrival.
Keep you folks posted!

Went back and found that in your initial thread.
You need to explain in detail what you've done and where you are right now. Don't replace parts on a whim, test them first. You should never have bothered your fuel pump without first confirming a problem with fuel pressure.
The injectors for the 3.4 DOHC are specific for that motor due to the spray pattern of 4 ports angled in a manner that directs two at each intake runner in the head although others will work.
Sounds like you have a wiring problem, or a code mask and ECM mismatch. At this point I believe it best that you start from scratch by properly programming the correct code mask into the chip. If you can't do that, don't do anything else until you correct the cause that is preventing you from doing so.
Afterwards you should be able to connect with Tunerpro. If you can't find out why as that program will tell you everything you need to know about the state of your sensors and whether or not they are working properly, or at all.
If you accomplish the above; proper code mask programmed in the chip with the correct ECM, connectivity with Tunerpro and proof of properly reading sensors, it should run normally.
If it doesn't, get a multimeter and back probe your ECM pinouts to their respective assignments and make sure you don't have anything connected backwards and that you don't have missing grounds, or grounds that are in the wrong place.
