Please help with codes!!!

[Houston Ben]

Hi all, I am at the tail end of my swap with a 2011 5.3 and 6L80 trans and have run into a problem. The engine will start and then die after approximately 10 to 15 seconds. I was able to borrow a code reader and when I hooked up the code reader I got 10 codes as listed:

P0036 Heater control circuit bank 1 sensor2
P0056 Heater control circuit bank 2 sensor 2
P0443 EVAP emission system purge control valve circuit
P0449 EVAP emission system vent valve solenoid circuit
P0452 EVAP emission system pressure sensor / switch low
P0463 Fuel level sensor A circuit high
P0480 Fan 2 control circuit
P0481 Fan 2 control circuit
P0690 ECM / PCM power relay sense circuit high
U01090 Lost communication with fuel pump control module


I erased all but 5 would not erase
P0443, P0449, P0452, P0463, U0109
I erased again and only 2 showed but forgot to write down which ones. I attempted to start engine and it ran for a few seconds but tripped codes again and died. Ran code scan and came back with 12 codes, all the same except for
P0054 H02S heater resistance bank 1 sensor 2
P0060 H02S Heater resistance bank 2 sensor 2
I deleted codes again and started, it wanted to run but codes tripped it again.

Does anyone know what these codes mean?? What can I do for these???? PLEASE HELP!!!
