from what i can understand is that the fuel pump worked before the swap?and now it doesnt? did you make sure all grounds are tight? did you check all fuses?

As for the ecu yes use the pr4 ecu not the hf

 

Check the main relay under the dash on the driver side. It is bolted to the side forward of the door. That is the most common reason for pumps not working.

 

check ur battery connections... that happen to my ef when i swapped a b20 into it...i couldn't figure out why i wasn't getting fuel and i check the connections and it was on the battery good but still i have to move it around then it started to work...
