Just fired up the heater in my garage and started diagnosing. Fuel pump recall was done last week, so new fuel pump. Solid 50psi while running.
Did the leak test and it holds about 42 psi over an hour, but at this point the engine was a lot warmer than last night!
I'm guessing my battery was a little weaker than normal, and/or the injectors could have leaked a little over night with these super cold temps, and i also didn't start the truck yesterday at all with close to the same temps as today.
I give up!!!

Also i don't think we have the IVN module in the E70's as i'm trying to diagnose a starting issue with another E70 but a 3.0 where the starter does one click for half a second.
I found the starter relay in the CAS module under the steering wheel with a burnt surface mount diode and a trace by the white starting relay on the board. if I jump the starter wire to the main power supply wire it starts.
This is another issue which i know is caused by bad ground from the body to the engine block.
