Can AutoZone test ignition coils?
While you’re under the hood, you may want to test the spark plugs as well.
Ignition coils can fail due to the heat and vibration of the engine, but the most common problem is faulty spark plugs.
It’s easy enough to test your vehicle’s ignition coils yourself with a few tools from your local AutoZone..
Can you drive with a bad ignition coil?
It is possible to drive with a faulty Coil On Plug (COP), but not advisable. Driving with a faulty wast spark ignition system won’t be possible. Driving with a faulty coil pack can damage other components of the engine.
Why am I not getting spark from my coil?
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
Do you need a resistor with a 12 volt coil?
If a 6 volt ignition system is converted to 12 volts and a Delco style 12 volt coil with an internal resistor is installed as part of the conversion, no external resistors are required. The 12 volt battery must be connected so the negative (-) battery terminal is connected to ground.
Is it hard to change an ignition coil?
Changing ignition coil is easy enough that you can do it on your own. Just make sure that you have the correct tools and the right replacement part.
How much does coil pack cost?
The average cost to fix the ignition coil is between $264 and $376. This price includes labor costs and the cost of the parts. The labor costs will range from $99 to $126 dollars. So if you replace these on your own, you will be able to save that amount of money.

How do you check the power of an ignition coil?
Locate the positive or power wire attached to the engine coil. Check for power using a test light. If this wire has no power, then your ignition coil is not receiving current. You should check the wiring from your ignition switch to the coil for breaks in the wire and repair them.
Why is my coil not getting power?
You may have a bad ignition module. You can check it by removing the affected ignition coil, also remove the fuel injector fuse. Connect a test lamp across the two terminals on the ignition module. Take a look at the test light while you crank the engine over.
Should negative side of coil have power?
if the points are CLOSED,you should have 0 or very little voltage at the negative side since all the voltage is dropped across the coil. the points act as the ground. turn the engine by hand and watch the points close and the voltage should drop near zero.
Will a bad ignition coil throw a code?
A shorted or open fuel injector solenoid, or a shorted or open coil will usually set a code, but a dirty or weak fuel injector or a weak coil probably won’t set a code. Bad spark plug wires are a common cause of misfire codes.
