No trailing spark

Ok I Have Done My Search And I Have Come Up With The Folloing:

I Have No Spark To Either Trailing Pulg Or Coil.

So Do I Replace Wires , Coils, Ignitors, Ignition Or All

Or Am I Wrong Could It Be Something Other Than The Above

The elders may give you a different answer, maybe one more precise, but I have always been told to work my way backward. If the plugs aren't getting fire, then go to the next connection back. Check for fire between the coils and the wires, for example. Check for fire from the distributor cap to the wires. That kind of thing. No fire there? Go inside the distributor and check the rotor button and such. Hope that helps!

If theres no spark at the trailing coil then your trailing igniter is probably bad. Theres a way to test it in the shop manual.

Check the condition of the cap/rotor first though. You never know....

If the tach is dead during cranking, ignitor, otherwise, coil, rotor or wiring.

Trochoid is right. Bad ignitor--no tach.
