Just finished rebuilding my 1992, 2.2 toyota camry engine. It was a headache just gething the cams to be in sinc. I finaly got the hole thing done and most of my sensors are new. But I started the car And it was runing great. But the next day, it wouldnt start. I put the scaner to it and it gave me trouble code 12(Engine revolution signal missing). I changed the distributor and it started, but it shut down in the next minute or so. Is it a faulty distributor or the knok sensor just went bad. I need help fast, because this is the secon distributor I got for it and it doesent seem to be the issue. I made sure all conections and grounds are connected. Could someone please help?

    code 12 is normal for key on engine off. it just means it did not see a tach signal. it should not be there with it running. then you have a issue with the distributor.
    are you using new distributors?? I hope so because used ones are not a good idea.

    Yes, they are Cardone rebuilt from Advance auto. I replaced it 2 times all ready and it just did it again. Im thinking maby they are defective, or maby I got a bad ground. But Im concern the most because im actualy beliving its the knock sensor. But I havent had time to do a more elaborated diagnostic.
