How do you diagnose the problem with a pulser coil?

To diagnose a problem with a pulser coil, first, visually inspect the coil for any signs of damage, such as cracks or corrosion. Next, use a multimeter to check the resistance of the coil; it should fall within the manufacturer’s specified range. Additionally, test the output voltage while the engine is cranking to ensure the coil is generating the appropriate signal. If the readings are outside the expected parameters, the pulser coil may need to be replaced.
