Why is there no spark at the tip of the spark tester?

While the engine cranks, you should see a bright, blue spark at the tip of the spark tester. If there’s a good spark, including the rest of the cylinders, the ignition system is working properly. If only one or a few cylinders have a weak or no spark, the problem is in the secondary side of the system.

Where is the spark in an ignition system?

Electronic ignition pickups are a component found on traditional electronic distributor ignition systems. They are located inside the distributor and function as the trigger for the ignition system to produce spark. The pickup coil monitors the rotation of the distributor and triggers the ignition system.
