Answer
 Hello Jerry:

 Send me the Make, Model, Type and Code Numbers Off of the Engine, Please. With these I can Locate a Breakdown and Better Assist you. If you have the Coil Shutoff Wire Disconnected at the Coil and Still have No Fire, the Coil May be Bad. Depending on the Model it May have an Igniter that Assist the Coil. The Model Numbers will help. Thanks.

 Respectfully

 John
