Hi, I am fairly inexperienced with cars, but yesterday I bought a pertrnix ignitor and coil and I am having problems starting my car back up. I thought that I did everything right, but the car is making the cranking sound, but it never turns over and starts the engine. I have the ground wire connected, and the black wire fromt he ignitor onto the negative side of the coil and the red on the positive. The litle top that goes over the tube coming out of the middle oft he distibuter is on and the ignitor is screwed down to the rotor, or whatever then name of that piece is. What am I missing? I have a feeling that there is a simple soultion. the instructions mentioned something about an air gap, and I didnt do anything invloving an air gap, I didnt even know wat it WAS. so I assumed that maybe that it has something to do with this. the instructions also said that the ignitor installs the same way as points, so if someone could please tell me what they think my mistake is, or clearly explain how to install points, I would be eternally thankful!!!
