Tech: Chevy Ignition Module Install
Thursday, February 9th, 2006
I drove my ‘87 Rangie home the night before, and it was running just fine. I don’t rebebmer if I worked on it or not, but the next morning it wouldn’t start. It didn’t even sound like it wanted to try. I quickly discovered that I had no spark. Great, the amplifier module is fried, and I don’t have a spare. I remembered hearing rumors that a GM module could be used with some minor modifications. I searched and searched, but could find no Rover related information about the swap, but I did find information. I found that the module I needed to try is a 4 wire module. The part numbers for the Chevy module needed are: NAPA ECHTP45 Wells DR100, Niehoff DR400, AC Delco D1906. So here is the story of what I did.
