I don't know if this has happened to anyone, but I can't figure out how to correct the problem. For a few months now I could not get my car to start, I changed/replaced just about every thing that deals with the ignition. Today, I found the problem; I only see spark when I ground the spark...

Ever since my MSD went out, my coils (or power transistor) have been making a high pitched tone. The thing is, the noise doesn't begin until the car is warmed up. When I rev the engine up to 6k, there is no change in the noise. It doesn't look like anything is affected because the car runs...
