Ok, I just swapped my friends 1994 integra rs with a gsr swap. Everything seemed fine till i cranked it. Started idling funny. Well it was a minor vacuum leak. Fixed it. Then the fuel pump went out. I replaced it. It was passing gas but still would crank. Then it went out again. So i just went and bought a brand new pump and still doesnt turn on when you open the igintion switch. I already changed ECUs and still i dont hear the pump turn on. What could it be?
