What makes a spark plug not fire on a coil pack?
Carbon deposits act like resistors effectively delaying the spark. A plug with worn electrodes would also fire late. But on a coil pack driven car, like the Corolla, firing happens by computer and is completely independent of spark gap distance.
Can a car not start with a faulty coil pack?
The coil pack within your car is an important piece of the ignition system. Without the coil pack properly functioning, the ignition system won’t work, and your car won’t start. Although numerous parts of your car are imperative and must work together in order to function at an optimal level, the coil pack may be one of …
Can a spark plug be replaced with a coilpack?
So basically, it would seem, that the best thing to do is to simply visually inspect the plugs from time to time and make sure the electrode wear is not excessive. If it is, you can either bend the electrode down a little to return to a more reasonable distance (if you are really cheap), or just replace the plug.
Can a bad ignition coil cause an engine to stall?
If one or more of your ignition coils under the hood begins to fail, this can cause the car to stall. The coils will send irregular sparks to the spark plugs. The electrical charge provided will be uneven and prevent the engine from running at a consistent and smooth rate. The engine stalling is a symptom of a faulty or bad coil pack.
Can a bad coil pack cause a misfire?
Ohm out the wire harness for the coil Pack for Cyclinder number 2: You may have a chaffed wire, bad ground, or bad connection at Coil Pack 2 ??

What should I do after replacing coils and spark plugs?
The code P0353 on this after you only had misfire codes and you changed the coil and plugs on cylinder number 3.

What happens when you have a failed ignition coil?

What should I do if my spark plug is misfiring?
I suggest first removing and checking the spark plug and swap in a new one or swap with cylinder next to it. This way the misfire moves to other cylinder then you know it was plug and replace it. If misfire still on number one then check for spark and injector pulse and replace injector or coil as needed. Was this answer helpful?
