aight, heres what happened. we hooked up all the power lines, fule lines, vacum lines and pluged in the old dx ecu to test it out. My old dx ecu works, but here is where things went wrong. All the grounds are hooked up by the way. We put the battery in and i turned the key. I got all my gageface lights, and headlights to come on. Then i pushed in the clutch. All good so far. Then I turned the key all the way and my freind said he heard one loud click from the starter motor. Then everything went black. I thought i saw a flash just before everything went out though. Now we cant get battery power to anything and no turning over of the starter. One Loud click then a flash then black now no power what could have gone wrong and what should i look to replace. plz help
