Water intrusion is an unlikely, and therefore, overlooked cause of ignition coil damage.

How do you test a ignition coil?

Connect your multimeter to the positive terminal or pin of your coil, and to the high output terminal that goes to the spark plug. Most ignition coils should have a secondary resistance falling somewhere between 6,000 to 10,000 ohms;however, refer to manufacturer specifications for the correct range.

How much does a new coil pack cost?

The cost of a new ignition coil depends on the make and model of the car. Some coils are as cheap as $75 while others cost in the $300 range. If you have the replacement professionally done then the labor costs will be between $50 and $100 per hour.

What causes a coil pack to go bad?

Excessive heat and vibration can cause the insulating material to break down and create internal coil failure. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.

Can ignition coils get water damaged?

Moisture is another cause of ignition coil damage, coming from the most likely and unlikely of places. … Overtime the seal between the valve cover and that spark plug tube can fail, causing oil to leak in and fill up around the spark plug and ignition coil.
