Spark Plugs spark once
My car suddenly didn't start. It’s been working great and now it won’t start. I've checked the injectors, fuel relay, fuel pump OVP relay, and they are good. The spark plug wires, distributor are new, and I checked the coil and EZL and CPS and they are all good on ohms. The thing that is puzzling is that my spark plugs only spark once. They have a nice bright blue spark, but the cylinders spark only once. One other thing I noticed was that my rpm needle goes up and down between 500 rpm – 1500 rpm when I crank the engine. This happens even though the engine spins at the sa
Experienced mechanics share their insights in answering this question :
Either a failing crankshaft sensor or impulse wheel could be the cause of the fluctuating RPM reading. The crankshaft sensor signal is often used to start both fuel pump operation and start the ignition coils with the camshaft sensor setting the sequential injection and ignition firing order.
You may want to have faults read out of the ECM prior to replacing the crankshaft sensor and look at the crankshaft sensor wheel. If the sensor is mounted on the front of the engine the sensor wheel may be part of the dampener and may have slipped or vibrates. If it is a sensor wheel that is part of the flywheel, a bent tooth may be the cause. To have this resolved, you may want to enlist the help of a mechanic, such as one from YourMechanic, who will have the equipment and expertise to correct this hard starting issue.

spark plug, also called Sparking Plug, device that fits into the cylinder head of an internal-combustion engine and carries two electrodes separated by an air gap, across which current from a high-tension ignition system discharges, to form a spark for igniting the air–fuel mixture.
Your car should have as many spark plugs as it has cylinders. Technically, an engine can run so long as at least one spark plug functions, but running with any spark plugs out of order can damage your engine. To keep your engine running its best, it`s always wise to change or repair your spark plugs whenever necessary.
A spark plug can fire 400 times per minute per cylinder or 1,600 times a minute on a four-cylinder engine,” said Rich White, executive director of the non-profit Car Care Council. “Many car owners delay spark plug repair on their vehicles, even after they have failed.
Your spark plugs are what supply the spark that ignites the air/fuel mixture, creating the explosion which makes your engine produce power. These small but simple plugs create an arc of electricity across two leads which are not touching, but close enough together that electricity can jump the gap between them.
There are three basic types of automotive ignition systems: distributor-based, distributor-less, and coil-on-plug (COP). Early ignition systems used fully mechanical distributors to deliver the spark at the right time. Next came more reliable distributors equipped with solid-state switches and ignition control modules.
The working cycle of both spark-ignition and compression-ignition engines may be either two-stroke or four-stroke.
Without spark plugs, some vehicles won`t start — or go anywhere. Because the health of this car part is directly linked to engine performance, bad spark plugs can often lead to more significant problems, including prolonged cold-starting and misfires during acceleration.
It depends on what type of engine and how fast the engine is spinning. The spark plug on a two-stroke engine fires once each time the piston approaches top dead center, which is once per revolution.
A spark plug works continuously to ensure your engine running. In a gasoline car, the fuel is mixed with the intake air in the throttle body before being injected into the combustion chamber. The spark plug receives a high-voltage charge from the ignition coil, causing it to spark and ignite the fuel-air mixture.
How many spark plugs does a car need? Only cars with internal combustion engines need spark plugs, and cars get one spark plug per cylinder. For example, a four-cylinder internal combustion engine has four spark plugs, while an eight-cylinder engine has eight spark plugs.
The ignition coil transforms low voltage from your car battery into high voltage. The spark plug takes the spark created by the coil to ignite the fuel in your engine.
When the ignition key is turned on, a low voltage current from the battery flows through the primary windings of the ignition coil, through the breaker points and back to the battery. This current flow causes a magnetic field to form around the coil.
Basically Convectional Ignition systems are of 2 types : (a) Battery or Coil Ignition System, and (b) Magneto Ignition System. Both these conventional, ignition systems work on mutual electromagnetic induction principle.
In two stroke cycle engines, the whole sequence of events i.e., suction, compression, power and exhaust are completed in two strokes of the piston i.e. one revolution of the crankshaft. There is no valve in this type of engine. Gas movement takes place through holes called ports in the cylinder.
1:fuel injection, 2:ignition, 3:expansion(work is done), 4:exhaust. The four-stroke engine is the most common types of internal combustion engines and is used in various automobiles (that specifically use gasoline as fuel) like cars, trucks, and some motorbikes (many motorbikes use a two stroke engine).
The first electrical ignition system or electric starter motor for cars was invented by General Motors (GM) engineers Clyde Coleman and Charles Kettering. The self-starting ignition was first installed in a Cadillac on February 17, 1911.
Dual Ignition is a system for spark-ignition engines, whereby critical ignition components, such as spark plugs and magnetos, are duplicated. Dual ignition is most commonly employed on aero engines, and is sometimes found on cars and motorcycles.
The ignition coil transforms low voltage from your car battery into high voltage. The spark plug takes the spark created by the coil to ignite the fuel in your engine.

Spark plug chaos. Rubber stoppers are preventing the spark plugs from coming out.
ANSWER : Hi there. Try using a pair of small needle nose pliers to pull off the rubber boots from the spark plugs. As you pull, twist the rubber boots to break them free. If you cannot get the rubber boots off, then try using some mineral oil on the boots to aid them off, then clean off the oil with soap and water with degreaser. If you need further assistance with removing the boots from the spark plugs, then seek out a professional, such as one from Your Mechanic, to help you.

After part replacements, spark plugs do not work – 1996 Lexus LX450
ANSWER : If you have a Check Engine Light on, first check for those codes to determine what engine management thinks is going on. If no trouble code, check the ignition fuse behind the driver side kick panel (carpeted panel at foot level on the left – for left-hand drive vehicles). If the engine is spinning quickly, and doesn’t appear to be meeting any resistance (as a motor with good compression would have), you may have a broken timing belt. If so – STOP, call a professional mechanic, like a certified technician from YourMechanic for help.

Just replaced spark plugs and wires and my car is still miss firing and I can’t pin point why and my old spark plug is oil covered
ANSWER : Hello there, many faults will cause your 1988 Ford Contour to have a misfire even after the spark plugs were replaced. When oil is seen on the spark plug this indicates that the valve cover is leaking onto the plugs. When this happens it fouls the plugs and can cause a misfire. Until the oil leak is addressed the spark plugs will continue to become fouled. If the misfire persists there are many potential causes such as the plug wires, fuel pump, vacuum leak, oxygen sensor, MAF sensor, or the cap & rotor. A qualified Technician such as one from YourMechanic will be able to diagnose your misfire fault and make any repairs required to resolve the issue.

Car turn over won’t start have new battery starter and altinator and changed spark plug and spark plug wires and crankshaft sensor
ANSWER : Hi there. The first thing I would recommend would be to have a professional mechanic complete a digital scan of your ECU to see if there are any stored error codes that might pinpoint the source of your problem. However, one thing you might want to check yourself is the electrical harness connected to the crankshaft position sensor. In most cases, if this is diagnosed a being damaged, it’s actually the harness that is bad and needs to be replaced.
