48vette

I have voltage to the HEI coil, but can not get any spark to the plugs. I recently replace the Ignition control module , coil, distributor cap and rotor and it did start and run for a short while. Now it will not start and there is no spark to number one plug.
Any help would be appreciated

Measure the resistance of the pickup coil. It should be around 800 ohms. They are known to crack and break into pieces.

I checked the pickup coil and it does measure 840 ohms.
Still no spark. I also checked the Ignition module and it checks out good.

Are you getting 12 volts to the distributor (pink wire) with the ignition on?

I would be looking at the coil. You might have a problem with the contact between the coil and the rotor.
