I am workin' on a buddy's car right now, and I was doing a tune up on it, and when i got all done it wouldnt start. So I did all the normal checks, and i found that it had no spark, the ditributer has an extra wire from it that it is suppsoed to go to, but i dont know where it is supposed to go. It has to atatch to something inside of the distributer. It is a green wire.
