I have the same setup... 1995 S14 chassis and a 1998 S14 SR from a Kouki half cut I have. The correct code for the ECU is NA, so unless someone changed the ECU sticker (which would be totally retarded) then you have the right ECU. Checking with a friend's car is perfect, but the part I don't understand is how your NA ECU ran your friend's red top!??
The problem I ran into with my swap was the same as yours and I found the issue was in my wiring. The fuel pump and start signal wires can get messed up because they have the same colors as other wires and can get confused. Once I took apart my harness and found where each wire was going I was able to get it right and presto!...3 months later mind you
Figure out why your ECU worked in your buddies red top and then if you have the right ECU and harness, and everything else you mentioned, I would have to believe your problem is in the wiring. Where did you get your ECU and original harness from?
