Welcome,this question may need more than a single answer. Please post back with additional questions on this at any time.
You may not have a good ground. Go to an auto parts store and buy an adjustable spark tester. About $10 - $15. Put it on the plug wire, clip the other end to bare metal and crank the engine.
If no spark test the stop circuit.
