New battery, solenoid, power pack, stator, coils still no spark?
Disconnected the black/yellow kill wire. No Spark?
What else could I check that could cause a no spark situation?
Are there more than 2 grounds on power pack? I only show 1, which is connected to the top of power pack.
I am testing for spark with a auto shop spark tester. One end in plug wire & the other on the top end of plug.
How should I check the key switch?
Yes, test the timer base. It is an integral part of the ignition system. If it does not put out the correct voltage, the engine will not spark. Use the cdielectronics.com troubleshooting guide-look for your specific engine.
