I have put a 93 gsr engine in a 99 civic ex, I use the ex loom on the GSR motor. I have converted it so all the plugs are in the right location and repined what was needed for it to work. So I go to start it and nothing. I am not getting 12volts at the ecu. The main relay is not clicking over for some reason. I dont have a spare yet so just wondered does that control the power to the ecu. Any help will be great thanks.
