Default cel codes help? Pleeze

Fault codes on JDM sti 02 engine.
Have recently done a full engine and loom swap.
Into bc5 RS.
Almost there boys
Starts and runs, but has a lil pop and misfire .

The configuration:
Running with just down pipe, hardwired external fuel pump no FPC, the relay as trigger, the front 02 is new, it's position is at the bottom of the up pipe.
Rear 02 is in down pipe. Running a rising rate fpr.
And removed charcoal canister. Td05 with boost pill in the waste gate vacuum line.

I'm getting the following codes:
P1237 - fuel pump secondary circuit
P1239 - exhaust control valve solenoid circuit low
P0444 - evaporated circuit open
P1230 - FPC malfunction
P1235 - ?? Misfire?
P1130 - air fuel circuit open bank 1 sensor 1
P1249 - ?? No idea
P0249 - waste gate solenoid waste gate solenoid
P1247 - ??
P1199 - Differential
P1237 - fuel pump secondary circuit

If anyone could take the time to check to see if my code IDs are correct and any info about how to fix my problem would be awesome.
I just want major/important codes sorted not fussed about minor ones. As I know my setup of fuel pump etc is causing some of them.

p1235 is a fuel pump thing, seems like you need to have someone go and turn all the fuel pump stuff of and then work to see whats left

Why not run a FPC? It looks like that would fix a few of the issues right there.

P0444 - evaporated circuit open- this you can just shut off since you know the issue- you got rid of the carbon canister.
