Hi, need some help please. In the final stages of doing my 4cyl to v8 swap and I can't find a clear answer. Car is a 90 2.3 and engine harness/o2 harness and ecu are from a 1990 as well. I tried to start the car and the fuel pump is not working. I keep reading the 4cyl have a ccrm? Do I have to splice in a fuel pump relay? Would it be same situation for AC? I can't seem to find a write up anywhere in the v8 swap forum on this issue.

Thank you
