Hey All!

So, I've been wanting a G35 or G37 for a while now and I ended up finding a nice 2009 G37x on Copart. Issue is, besides it being a Copart car, they never charged the battery, left the windows down, and then used it as a trash can.

After about 2 days of scrubbing, degreasing, cleaning, and applying protectants, you can officially get in the car and not instantly want to gag or feel like you need to check your tetanus shot records. I've slowly pieced the car back together as the window regulator cards and door cards were removed and the passenger door latch decides when it wants to work (replaced with an OEM latch and cables).

Now for the fun part, the hood latch lost the metal end (inside the car below the steering wheel) due to them trying to pull the latch open. I followed the latch wire, pulled the wheel shrouds down and was able to open the hood. I put the battery on a trickle charger, but wanted to see if I can pulls some codes and see what nightmare or dream I had ahead of me to get this running and driving. Well, here's the list it shot at me:
U1000
U0415
B2014
B2553
B2557
B2562
B2601
B2603
B2604
B2605
B2607
B260A
B260F
B2612
B2617
C1704
C1705
C1706
C1707
C1708
C1711
C1729
U1300
U1256
B2109
B210C
B210E
P1721
P1815
C1155
C1109

My question (and prayers to the Infiniti and Nissan Gods) is can this just be the fact that the battery was probably dead for over a year and I pulled the codes on a low voltage (5% charged) battery? Or have I just bought a money sink?

Any information would be greatly appreciated. Sorry if this is in the wrong place, but I needed to get help.

Hope it was bargain!
Yes, wait for it to fully charge or replace the battery.
Clear the codes, then try again
