Me and my freind just finished dropping in my motor, B18CR, and we started to start up the car. It cranked, and cranked. Then, when it cranked again, something went "Pop", like as is something sparked...and lost all power to the car. We used a battery jumper box(which was fully charged) or whatever its called, and it still is not getting any power. All fuses seemed fine, checked all the ground wires too. What I dont understand is, if the battery jumper is connected to the battery, wouldnt there at least be power throughout the car? Nothing electrical works at all. Is it possible to short the ecu? Please help!! Trying to at least drive this damn car before it starts snowing!!!
