So this car I bought for $700 for a non start. So I got my analog volt meter and put it into OBD1 and it was showing a blown ECU. I found a 90 GST Eclipse ECU so I snagged it up. I changed around the prongs 6 and 14 on the ECU plug in. The car started right up!!!!:hell yeah: Put the check engine light came on and it seemed like the mass air flow sensor was unplugged. I unplugged it and plugged it back in but the same problem. So i checked the OBD! again and it was showing the readings for the mass air flow sensor. But I read that if you did the prongs wrong it would do the same thing. So do you think i did it wrong somehow? Or maybe the mass air flow sensor is bad?
