Okay I need your help. I was driving down the road at about 60 when my Celica just died! The RPM's dropped the check engine light flickered and then nothing. I coasted to the side of the road to restart it and it wouldn't crank and all, another funny thing I noticed was that the CEL didn't come on when I tried to turn it on. I replaced the Main relay, and the battery, alternator, and fuses are all good. Can anyone here tell me what I'm dealing with? I'm thinking that maybe the ECU and Ignition aren't getting power? But I could be wrong any ideas?
