i have an r32 with an rb20det and the ecu isnt powering up, it was fine a week ago until we took the motor out to fix the sump gasket and install a 25 box. everything is plugged back in and now the ecu wont power up, the headlights and tail lights work so does the central locking. there is power to the main fuse and engine Cont. fuse. any ideas on what the issue could be?
