You have a problem with the distributor assembly. I recommend replacing the distributor assembly. This will replace all the possible sensors and coil for the ignition and fix the problem you have.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
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.
If the ignition coil does not have spark, it`s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
A Bad Crankshaft Position Sensor The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.
Worn/failed spark plugs, coil packs, or spark plug wires can trigger your check engine light to come on. In today`s cars, say Firestone Complete Auto Care technicians, if a plug starts to fail then the most obvious event should be the check engine light coming on or even flashing.
One of the first symptoms of a problem with the ignition module are engine performance issues. If the ignition module fails or has any problems it can lead to performance issues with the vehicle, such as misfires, hesitation, loss of power, and even reduced fuel economy.
The most common causes of misfires are worn, improperly installed, and mishandled spark plugs, malfunctioning ignition coils, carbon tracking, faulty spark plug wires and vacuum leaks.
your engine misfires and shakes: if a map sensor reports a false high pressure reading, the engine`s computer will signal for more fuel. this results in a rich mixture, which can foul the spark plugs and cause a cylinder not to fire.
The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.
Bad spark plug wires can interfere with the electrical current flowing to the engine, making it difficult for the engine to complete the combustion cycle. An incomplete combustion cycle can cause an engine to misfire, which means your car may jerk, stumble, or briefly lose power.
Engine stalling
One of the first symptoms of a bad ignition pickup is an engine that stalls. An old or failing ignition pickup may cut out signal intermittently, which may cause the engine to stall. The engine may suddenly just shut off, almost as if the key had been turned off.
The ignition control module is a solid-state switching device that controls the operation of the ignition coil or coils. It is a small, high-current circuit used to ground the negative side of the coil in order to build charge.
Car suddenly stalls while operating: One of the most common symptoms of a failed ignition relay is a car that suddenly stalls while operating. If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system.
A difficult start could be due to a number of things, from a dying battery to a faulty starter. But if your vehicle has a hard time starting after sitting for just a few hours, it can cause an extra layer of confusion. When this happens, one of the most common causes is low fuel pressure.
Bad Spark Plugs
If the engine holds compression well, and the fuel system is working correctly, but it still won`t start, that tells us that your car`s spark plugs may not be working. The spark plugs ignite the air/fuel mixture inside the engine`s cylinders. It`s the resulting explosion that actually powers your car.
A clogged or failed exhaust gas recirculation or crankcase ventilation valve or faulty oxygen sensor can send the wrong signals to the computer and cause misfires.
A dead battery is one of the most common reasons why your car won`t start. Check the battery terminals for corrosion and clean them using a wire brush or battery cleaning solution. If the battery is old or damaged, it may need to be replaced entirely.
Make Sure the Gas is On
Therefore, the first step in diagnosing ignition failure is to make sure the gas is turned on. If your furnace starts after the fuel source is turned on, you`ve solved your problem.
The ohmic resistance of the coil is around 0.2–3.0 Ω on the primary side and around 5–20 kΩ on the secondary side.
Reasons for failure of the camshaft sensor can be: Mechanical damage. Break in the encoder wheel. Internal short circuits.
The most common failure is the crankshaft position sensor. These fail much more frequently than the cam sensor and will cause a no start. It can also occur if the timing belt broke or jumped a tooth. I would do a compression test also to see if there is low compression.
As the MAP sensor fails, it can cause various issues with the fuel system and vehicle performance. An inaccurate reading from the sensor will cause the computer to change the amount of fuel it sends, which can rob the engine of power or cause it to run poorly.
Hard start symptoms and starter failure may NOT be caused by the starter, but could actually be caused by the crankshaft position sensor. If your vehicle is experiencing one or more of these symptoms, the crankshaft sensor may be at fault.
The O2 sensor will not cause the no start. The no start can be caused by the fuel pump or the ignition system. You should check the engine for spark and fuel pressure, when it is not turning on to help narrow the problem down.
make sure every ground wire is connected properly . Some loose ground wire could even make your vehicle not to start. Yes, it will cause a misfire, just dirt on a coil can cause a misfire, bad plugs, wrong plugs, wrong wires all can cause a misfire even a sticking valve can cause a misfire.
