starter works but engine won't fire. Gas ok, there is voltage on pink wire going up under flywheel. There is a black wire going up to the coil, is it supposed to have voltage on it or is it a ground? Help
The black wire is just a ground. Take one of the stark plugs out and watch the stark plug while cranking the engine. If there is no spark, you may have a faulty ignition module. Does your Craftsman have the original Briggs & Stratton I/C engine. If so, punch in your engine numbers at the Briggs & Stratton website and download a manual, that should have a trouble-shooting section that could help you diagnose the problem.
