I have no spark, already changed ignition coil, ignition module, pick up coil, spark plugs,wires, and distributor cap. I have 12 volts at the coil but when i put a good spark tester on i get no spark. I’m at my witts end please help
The next step would be to check the wiring harness. Being as old as it is the wiring may have become damaged. Also check and clean any ground connections. Use the wiring diagram to help trace and check the wiring on your vehicle.
