Does the Spark Plug Create the Spark
The question, "Does the spark plug create the ignition spark?" is a very common one to have after changing a worn-out plug or after installing a new plug but how do we know which one? A plugged up or damaged plug will not create an ignition but if you have the ability to see a black smoke odor coming from your vehicle this is most likely the case. It is highly suggested you have the vehicle inspected by a professional before attempting to repair your own ignition spark plug
You should also know that the vehicle codes will vary between vehicles so it is best to have the vehicle checked by someone qualified as they will be able to determine which type of plug your vehicle has. There are three different codes for plug wires so once you identify yours it is a simple matter of finding the corresponding fuse and removing it in order to replace the plug. Once you have replaced the plug, it will be time to run the vehicle's engine for a few minutes to see if the vehicle starts. Once again if there is no fire then the wires may be faulty and need to be replaced.
A faulty or bad plug may be caused by a number of factors but usually include losing factory warranty, improper installation, poor wiring, loose bolts or screws and even worn out spark plugs. One of the easiest ways to tell if your vehicle requires a replacement is if you hear a popping or crackling when you first start the engine; this is usually an indication that the plug needs to be replaced. If you notice the vehicle makes noise when starting or when cold then you will most likely need a new plug. With the correct plug in place and your vehicle on a flat or incline the spark should be lighting easily and the carburetor should be working efficiently.
