Second Attempt to Start: Engine Turns Over, No Spark

What happens here

After installing the new ground wire, the creator attempts to start the Willys Jeep again, applying starting fluid to the carburetor. This time, the engine successfully turns over, indicating improved starter function, but it still does not 'fire' or run on its own. He connects a voltmeter to check the coil's voltage, confirming adequate power (4.7-4.8 volts) is reaching both sides of the coil and the top. Despite this, there's no visible spark from the spark plug when tested. He deduces there's an issue with the spark delivery.

Goal: Confirm starter engagement and diagnose lack of engine fire
