Why do I need to replace the spark plug wire?
Every time the ignition cables are replaced, the spark plugs should be inspected. Leaking oil or coolant can cause ignition wire failure. If this is the case, the cause of the leak should be repaired or replaced, or else the new ignition wires will quickly be damaged as well.
Can a spark plug not ignite without a good spark plug?
Well, my response to this question is yes, and that is because the spark plug wires are what makes possible for the spark plug to get the required voltage jolt of electricity from ignition coil in other to ignite the spark plug. So without a good spark plug wires ignition of the plugs will not occur.
When to change spark plug wires, Ricks free auto repair?
The actual value you get from testing each wire isn’t as important as the consistency between the wires. So if you test a 3-ft spark plug wire and get a reading of 10,000 ohms, all other 3-ft. wires should test the same. So if you find a wire with significantly less or more resistance, you know that it’s defective.
What to look for in a bad spark plug?
What to Look For. Be sure to first check spark plug wires for visual damage. Look for any signs of melting or cracking. The following situations call for immediate replacement of spark plug wires: Vibration damage – Constant wear and tear caused by engine vibration can loosen the electrical connection at the spark plug.
Can you replace the spark plug on a Hyundai Santa Fe?
Replacing the spark plugs on a Hyundai Santa Fe is quite intensive and most owners choose to let the dealership perform the procedure. But there are a few that would want to do it themselves.
Do you need to replace spark plug wires?
Damage: It’s possible for spark plug wires to be damaged. If the insulation is compromised, or there’s an internal break, you’ll need to replace your wires even if it’s not yet time.
Are there still spark plugs in newer cars?
Some later models have an ignition system without a distributor, but they still have traditional spark plug wires. Depending on automaker, those harnesses started to disappear in the late 1990s/early 2000s. Newer vehicles have a coil-on-plug ignition system that eliminates electrical problems caused by worn-out spark plug wires.

So if you find a wire with significantly less or more resistance, you know that it’s defective.
How often should I replace my spark plugs?
Inspect the spark plugs. Clear the codes. Ignition wires should be replaced at least every 60,000 miles, but whenever your car is serviced, it’s a good idea to have the entire ignition system inspected. Any time that you have spark plugs replaced, it’s a good idea to have the ignition wires replaced as well.
How are spark plugs used to start an engine?
They transfer the spark from the distributor or ignition coil to spark plugs that ignite the air-fuel mixture, starting the engine. Over time, the cables can get weak and break down. This will make it harder for the spark to reach the engine cylinders, resulting in engine misfires.
Can a bad spark plug cause a car to not start?
The car may not start at all. If one of the spark plugs has gone bad, the car will still start and run, but it will run poorly. Ignition cable failure is often caused by other failing pieces in the ignition system; a mechanic should check for any other malfunctioning parts, and replace any parts of the system that don’t work.
How are spark plugs connected to the ignition coil?
Spark plugs ignite the air-fuel mixture in the combustion chambers of the engine cylinders. See the 4-stroke animation. An ignition coil can be placed right over the spark plug (coil-on-plug) like in this illustration, or connected to the spark plugs through spark plug wires, like in this photo.
Are there spark plugs in an old car?
Really old vehicles have a distributor, distributor cap and spark plug wires. Some later models have an ignition system without a distributor, but they still have traditional spark plug wires. Depending on automaker, those harnesses started to disappear in the late 1990s/early 2000s.
Why do I need to change my spark plug wires?
However, there are other factors that can play a role in the timing. Damage: It’s possible for spark plug wires to be damaged. If the insulation is compromised, or there’s an internal break, you’ll need to replace your wires even if it’s not yet time.
Is it possible to replace a coil and spark plugs?
Yes. If that is the case then try switch the boots (i take it they are not apart of the coil pack) and see if it happens then. Basically try to track down what part it is by switching stuff around.
