l put jump leads on wrong way and now l dont even get lights even after changing a battery no clicks not a kick HELP!!!!
fuses are good and checked could it be the ECU

ck fuses.

Oh my. thats not good

Did you check all the engine fuses as well? (There is a fuse box in the engine in addition to the fuse box on the interior of the car)

You should get lights or something even if your ECU were fried as the lights arent tied into the ECU. l would guess you blew some of the 50amp fuses in the engine bay. But it could be far worse..
