Another Cold Start Issue

[rezs1ckness]

My 2007 Nissan Frontier M/T will continuously crank on cold mornings (below 25 degrees). Jumping the vehicle will get the truck to start with no problem at all. Here's a list of things i've tried to diagnose the issue. Has anyone experienced an issue like this before? Any idea on what's causing it? I'm out of ideas.

- Replaced battery twice.
- Read somewhere that the ECM could be frozen. Like a cell phone that doesn't work because it's too cold. Took the ECM out overnight and connected in the morning. Still cranks.
- When temperature hits around >29 degrees. Truck starts just fine.
- Took a spark plug out and used jumper cables to connect it to negative battery terminal with it's coil pack attached. Had someone try starting truck. Truck started without any problem at all.
- Checked body grounds. They all look fine. Didn't do any voltage testing on them though.
- Did some parasitic drain testing. Stays steady around 80mA.
- Batteries never seem to stay around 12.6v. Ends up being anywhere between 12.3-12.7.
- Battery terminals and clamps look alright. Took some light sand paper to both just in case something funky was on them.
- Because truck starts fine with jumper cables attached, i'm assuming fuel pressure and fuel pump are fine. I don't believe there's a fuel pressure test valve on this truck.
- Put some seafoam in the gas tank in case any water was in there that would freeze and clog fuel lines?
- Tried disconnecting MAF, no difference.
- Throttle body looks fine.

As an update; I was checking out my starter the other day and moved the cables feeding into the starter around out of the way. This must have corrected a bad ground in the wire because the truck started right up without any issues this morning (about 4 degrees in the morning). Fixing this issue also corrected a couple other problems I was having with the truck such as my passenger side A/F sensor throwing codes, door locks being spotty and unresponsive, and key fob being slow to lock and unlock car. I couldn't believe how many problems a bad ground could cause. Those dam electrical gremlins!
