I also took a look at my noise filter, and its grounded to a point on the ignitor bracket, and is a small black resistor looking part. It has that white connector with two wires, one black with orange stripes, and one white with black stripes. I can take a picture of it for you if your would like. I cant say for sure if that would give you an ignition issue, because I have my car half tore apart, and cant fire it up at the moment.
