I am having trouble starting my 92 sundance, 2.2 Auto trans. The engine turns over like it is going to start up, but it doesn't because it not getting any spark. I have replaced the distributer cap, rotor, distributer shaft, and that round thing in the middle of the two. The spark plug wires are fine. It is getting power all the way to the distributer cap, but yet I get no spark. If anyone could help me, please help!
