Hi mate, check all fuses, in the engine bay, front boot(frunk), and in the interior(drivers floor).

Other people have done it a few times at work and it turns out to be just a fuse(usually a main 75a one)

I know of cases where the fuse doesn't blow quick enough and the power and ground went right to the ecu and fried it before the fuse disconnected the system, but better of looking for dead fuses to start with.

Oh no... Check all the fuses and fusible links and reassess.

hi
i had a flat battery on a 1990 3sgte and i put jumpers on the wrong way to jump start it, jumping battery was sitting on the ground to jump not in a started car so i'm hoping that helps me a little
can someone tell me what possible fuses i may have blown and or problems i MAY encounter apart from the ecu {fingers crossed that is ok}
I just replaced the alternator 2 months ago so im hoping that isnt #%#$@##'d

i noticed the fusible link off the positive on the battery has blown
fan instantly works when a good battery is now connected
i also read somewhere about an am2 thingy which i could see in the "Frunks" fuse box but don't know what it is could be shot also

i got the brb electrical manual to help me along as well
thanks for your time
