H22a swap in a 97 civic. I put the ecu in and turned the key and all i got was a "click". So i thought mabey the battery was just low. Grabbed some jumper cables and tried again. All i got a was a click from the starter and an even louder click from the ecu. Engine didnt turn at all. Then i get the wonderfull smell of something burning, pulled the cover of the ecu and it was all burnt up. Any ideas of what went wrong?
