Colt, control light no longer glows and doesn’t start again

Hello you dear autobastler, after I have now googled about 5 hours in the net and to my problem really found nothing more precise, I have registered myself like many others here also in the emergency after help. so, immediately to my problem, I have a mitsubishi colt bj 92 113ps I hope that is enough for now, my problem has gone 6 months, the car went in the last 6 months in the middle of the drive just from the approx. 8 times and in the middle console so behind the radi o although the ignition was still on it has clicked a while, so a bit loud noise as if you were turning something on and off all the time, in the time what always about 5 minutes long went so this click on and off, the car didn’t jump on either, when the loud click stopped he jumped again and again without any problems as if nothing had been. yesterday, the car went out again to happiness also where I could stop right now, this time this click just 10 seconds then it stopped again, at the same time when I wanted to try to start the car again, it was smoking under the handcuff a bit rough out a mega stank as if what had gone through, I got out with a shock that the car would burn here place and place, thanks to God the smoking stopped after about 1 minute, which is also my question, what the devil could have been? I am aware that where the smoke came from the control unit and the d the whole wire harness is near, another shock would be it now if it has caught the control unit since the ne is very expensive thing, could be something completely different? and besides, the car now does not start at all, ignition is there, motor noise at the start also but it just doesn’t start. not to forget the control lamp so the check engine lights up when the ignition is no longer on. so no longer at all. could someone possibly pass on to me 11en ? problem or cause search what it could possibly be ? the normal safeguards I have all overcrowded, are all ok. maybe you can help me there in advance ? nice greetings Ricardos
