Welcome to the forum. I hope we can help you.
Judging from the fact that you mention what sounds like 2 stroke ignition parts we're assuming you have a Chinese 2 stroke. It's always best to tell us what engine you have when asking for help.
My first question would be how are you checking for ignition (spark)?
Have you tried it with the kill button disconnected?
Have you confirmed good electrical connections between the blue and black wires? Those kit supplied push-together connectors can cause problems.
