Exclamation SoCal Desperate for PFC/Stock ECU help

So i'm quickly running out of time to get my car running so i can drive it for work due to my wife recently starting school and now i'm having possible ecu problems.

So to start here is my mod list:
Apexi Power FC with oled commander
Downpipe, hi flow cat, apexi cat back
Intakes
Intercooler
Koyorad Radiator

A few weeks ago I put the radiator in, never had problems with the car starting and after the install the car would start for about 4-5 seconds then stall. Nothing is wrong with MAP sensor and I replaced the fuel pump and fuel filter yesterday. Last night it started for about a minute after the fuel pump and filter then stalled again. So today it would still start but then stall so I dropped my Power FC in the car for the first time, I reset the FC to the base map and tried to start the car but now the car will only crank and crank but not fire up. Does ANYONE have any tips on tweaking the power fc to get my FD running for 2 weeks so i can get it down to Neptune Speed for my tune. Running out of time and options lol any help would be appreciated.

Lets see if this time line is correct as per you statements.
1. The car ran OK on stock ECU.
2. You installed Koyo rad.
3. Now engine stalls after installing the Koyo.
4. Installed PFC ECU and problem still exists.

If so; you screwed up some wiring during the Koyo install.
You first have to determine what you messed up doing the Koyo install before going anything else.

Yes that's correct except with the PFC now the engine just cranks not even fire up. Do you have any pictures or know exactly what wiring I should be checking?

Did all that weeks ago, that stuffs good.
Today i took off the UIM and found 2 wires that connect into a plug idk i think its called the BAC? Anyways went and reattached those and fix some silicone hoses that were loose, coming off etc. Battery is dead from sitting for like 3 weeks so gonna charge it tomorrow and hope it fires up.
