My car has been sittin for a little bit and yesterday I added some fuel and tried to start it(I used a different ECU too). It cranks, but won't fire. The fuel pump doesn't turn on at all(relay is good), and there's no spark. Is the ECU the problem? Could it be something else? Also another thing; I had tried to hook the fuel pump directly up to the battery by wiring the black and yellow/white, but nothing happend.??
