4th wire isn't usually used, if it is connected to anything its to reduce interference ( Can;t remember specifically what the component is called)

 

 

You need to check that you have power on that plug when you turn the ignition on.

 

Got a crank sensor plugged in?

 

Got the wasted spark type ignition amp, NOT the original 205 amp?
