I have an M100 too. I can say from direct experience that the ECU for these don't like being shorted out - mine burned part of the pump power circuitry when the pump lead shorted, meaning it would not come up to idle properly. So maybe your lead somehow shorted when it came out? I'd be thinking it's the ECU.anyway.
