Hey everyone/anyone. I have a bizarre problem with my 91 zx2+2 NA. As far as I can determine, it has no alterations beyond a pair of run of the mill aftermarket mufflers. My problem is that when the ignition key is turned off, the car remains running. Some symptoms are: rpm drops, gauges all shut off. I believe fuel pump remains on, though I haven't checked this by listening for it, but car ran for approximately 3-4 minutes after key turn, so I think it's remains on. Any help would be appreciated. I saw a IG reel that was about engine swaps having this problem and the cause was a problem with the alternator backfeeding the key. Can't see that that would be my problem, though I have yet to install a new trans/alt wiring harness. Hoping that cures it. But any assistance would be greatly appreciated.
