Well The wifes truck had officially given us our first "problem"... and its a good one LOL
Getting a P069E and a P0191 and some lean codes also. Cleared the codes and the truck will run fine, rev etc... no problem for about 15-20sec and then it'll bog and die. I havent attempted to mess with the fuel system on any 07+ trucks and am aware of the module etc... I'm sure someone has ran into this BS before... What to do?!?!
Our reg cab is down with the trans out of it and now her truck is KIA... awesome...

I Looked real quick and didnt see a PID for it. I honestly didnt spend a lot of time with it tonight. Its sitting in her office parking lot backed in a space, I had to push the SOB about 40yds 
to get it into a parking space to leave for the night. I'll go back tomorrow and do more diag. It was 40deg with 50mph wind gusts... I really didnt want to spend much time out there LOL...
The fact that it'll run fine for a few seconds and then the SES comes on, then runs like shat sort of points toward the pump itself being ok IMO... The truck only has about 80K on it...

On that year vehicle, they don't specifically call it fuel pressure. Its injector pressure delta. Those codes point to the FPCM...
greeeeeaatttt..... LOL
Yeah, I didnt even think about it not being called actual FP. I'll have another look tomorrow.
from what I understand, you've gotta buy/replace the module and then a dealer has to flash it?
I wish I could get ahold of the GM workshop manual for this thing and go thru the pinpoint tests for the module. I'd rather do that and spend 20min and save several hundred bucks in diag fees than pay some goober to misdiagnose it and waste my money...

I should have all the harness info for the FPCM, if you want it... I had to dig into all that when I E38 swapped my 04.

From what you are describing. You need to look at the fuel pump. The p069e is a warning code that the fpcm sends to the ecm to tell it that something is not right. The lean codes are probably from the fuel pump laying over and not supplying the proper pressure. You need to put a fuel gauge on the fuel rail port and see what the pressure is doing. See if you can find a pid for commanded fuel pressure and compare the command to the actual.
