P0171 Lean Bank 1 - This was stored when I ran the codes
P0174 Lean Bank 2 - This showed up after a clear -

Then my car died After letting it get hot for a while, We took a break, I went to leave, and it sputtered and stalled until sufficient time passed it cooled and was able to start.

We are possibly leaning twords a fuel issue now that maf codes are gone.

Failing pump?

Just to be thorough and for knowledge in the post, Here is a full list of codes that first pulled some may be redundant and coincidence from messing with stuff, most are my steering lock (pulled fuse) I think.

B2014 - Chain of Steering lock BCM
B2562 - Low Voltage
B2607 - Lock Relay
B2609 - Lock Status
B260A - Ignition Relay
B26E8 - Clutch Interlock Switch
B2109 - Lock relay off

Engine stuff

P0300 - random multiple Misfires
P0171 - Too lean Bank 1
Po174 - Too lean Bank 2

Thats all I got this time around.

And Which relearn do you speak of exactly? Idle relearn?

Also lslightly off topic, but SouthArk or anyone, do you know What shape fuel Strainer we have? Is it the Moon/Half circle shape? Or square bag shape?
A lean condition is caused by 2 primary things, air & fuel. If the MAF sensor doesn't read the air flow correctly, the ECM compensates by altering the injector duty cycle (length of time open and size of aperture). Some common problems that are starting to appear on 09-11 models are the fuel pump 'hats' breaking off and the pump is laying in the bottom of the gas tank. Phunk (CJM) has a fix for that.

The pictures I've seen in the parts catalog from Nissan is that the strainer is a rectangular 'sock'. But they could be using a 'generic' picture.
