Ok fellow beemer night riders ..My check engine light doesnt come on and the car wont start. I was hooking up a switch to my a/c fan and little did i know the switch was resting on the frame passenger side, door rail panel was removed for cleaning.. And there was sparks minor finger burn when i hooked the wire up. I know it was a half baked job .What do I do now?

I replaced the white relay, bought a new ecu and it still doesnt start.1995 bmw 318i sedan.
