i'm very interested in this situation,i'm having the same problem with my 91 corrado. I had a swap done from 1.8 to vr6 worked well for a while so i did some refurbishment of the corrado and did a rebuild of the vr6. However since that was taking long i bought another vr6 and had it put in and started it now i dont get fuel and the same voltage you see at the pump fuse 18 no pwr and the relay seems not working. I bridged the big pins and the pump came alive like i have never heard it before.That didnt even get it started. I took the fuse box apart used another one same issue. I fail to believe its the ecu cause at one stage i had the engine running dont know what to think. Its very frustrating and its causing me to think about selling the car. What did you find that was causing the problem. I change the harness for the fuel pump on my corrado so that i could use the big pump in the tank. I change the tank also the harness all worked back. Its mind boggling.I bet its something simple. Also you said due to it being an obd2 you dont need the ecu relay in position 3 for relays?I'm willing to fly someone in to make it work,i live in barbados by the way. Let me know whats up.
