Symptoms of bad pulser coil has to be checked if an engine is not functioning well.
This is because for an engine to perform well, the ignition system plays a vital role.
The pulser coil is a component of the ignition system that helps time the spark that is being released to the ignition coil.
If the pulser coil is bad, then there will be a wrong timing for release of electric charge to the ignition coil.
Due to this, the performance of the boat or automobile will suffer.
Some of the symptoms of a faulty pulser coil include inconsistent spark timing, vibration of engine, engine backfiring, loss of power at high speed and reduced engine power.
These problems will end up reducing the performance of the engine.
To avoid this, you have to make sure that the faulty pulser coil is replaced with a good one when it is damaged.
This will help maintain a good and consistent engine performance.
Symptoms Of Bad Pulser Coil
1)Poor fuel economy
For power to be released from an engine, combustion has to take place.
This is when the fuel mixture is burnt in the combustion chamber.
But for this to be possible, the spark plug has to deliver the needed electric charge to help ignite the fuel mixture in the combustion chamber.
Without this, combustion will not take place.
But sometimes the spark plug can deliver spark to the combustion chamber at an irregular pattern.
This will affect the combustion of the fuel mixture in the combustion chamber.
Due to this, incomplete combustion will occur.
When incomplete combustion occurs, fuel mixture will be expelled from the combustion chamber without completing an efficient combustion.
This will show up in smoke from the exhaust system.
Due to this, there will be a poor fuel economy due to wastage of fuel through incomplete combustion of the fuel mixture in the combustion chamber.
Apart from having a poor fuel economy when the pulser coil is bad, the performance of the engine will be affected negatively.
When the pulser coil is faulty, it can cause the ignition timing to be shutdown.
This will lead to a variety of problems that include backfiring.
Backfiring is a problem in which the engine experiences an explosion in the intake or exhaust system.
This explosion leads to a loud noise.
When the pulser coil is faulty, it can cause the ignition timing to be incorrect which can lead to an incomplete combustion of fuel mixture in the combustion chamber of the engine.
This incomplete combustion in the combustion chamber can cause fuel mixture that are not burnt to enter the exhaust system thereby causing a backfire.
3) Ignition system failure
The ignition system helps in producing the spark needed by the spark plug for ignition of fuel mixture in the combustion chamber.
But for the ignition system to be functional, it has to be able to produce the needed spark.
Apart from producing the needed spark, the ignition system has to send the spark at the right timing.
Concerning sending the spark at the right timing, the pulser coil helps in making sure that this is possible.
If the pulser coil is bad, the generated spark will not be sent promptly.
Due to this, the ignition system will not function well to aid efficient combustion of fuel mixture in the combustion chamber.
4) Loss of power at high speeds
Any time more acceleration or speed is needed, it is the duty of the engine to help achieve this.
To help achieve this, the ignition system has a huge role to play.
This is because before an engine can produce more speed, it has to burn more fuel mixture in the combustion chamber.
This is what will help in the rapid movement of the piston to produce higher rpms.
But for this to be possible, the combustion of fuel mixture in the combustion chamber has to be efficient.
This is what will help produce the needed power.
But for the combustion to be efficient, the ignition system has to supply the spark plug with the needed electric charge.
If components of the ignition system like the pulser coil is not functioning well, the ignition system will not be able to supply the spark plug with the right charge at the right time.
This is one of the symptoms of bad pulser coil.
This will affect the efficiency of combustion in the combustion chamber.
Due to this, there will be loss of power especially at high speed.
5) Rough or erratic idling
A pulser coil is a component in an engine’s ignition system that generates electrical pulse to trigger the spark plugs to fire at the correct time.
When the pulser coil is faulty, it can cause the engine to experience rough or erratic idling.
This is because a faulty pulser coil can send wrong signals to the engine control module (ECM) which can cause the engine to misfire or run poorly.
If the ECM receives inconsistent or incorrect signals from the pulser coil, it may not be able to adjust the engine’s fuel and air mixture properly.
This can easily lead to rough idling.
A faulty pulser coil can also cause inconsistent spark timing thereby leading to misfiring and rough idling.
The pulser coil works in conjunction with the crankshaft position sensor to determine the engine’s RPM and position which is critical for proper spark timing.
If the pulser coil is not functioning correctly, it can cause the spark timing to be off thereby leading to poor engine performance and rough idling.
6) Poor throttle response
The throttle is the medium in which an operator sends a signal to the engine for speed increase.
For this speed increase to be possible, more combustion of fuel will take place in the combustion chamber.
This is what will help in producing the needed power from the engine.
But if the pulser coils is bad, it will withhold the ignition coil from sending timely spark to the spark plug.
When this occurs, efficient combustion of fuel mixture in the combustion chamber will not take place.
Due to this, acceleration will not occur fluently due to poor throttle response.
This will directly lead to reduced and poor acceleration from the engine.
7) Engine vibration
Another sign of bad pulser coil is high vibration of engine.
A faulty pulser coil can cause engine vibration in several ways.
The pulser coil is a very important component in the ignition system that generates the signal to trigger the spark plug to fire.
If the pulser coil is faulty, it can cause several issues that can lead to engine vibration.
One way that a faulty pulser coil can cause engine vibration is by causing misfires.
If the pulser coil is not generating the correct signal to trigger the spark plug at the right time, it can cause the fuel mixture in the cylinder to ignite improperly.
This can lead to misfires which will make the engine to vibrate as the combustion process is disrupted.
Another way that a faulty pulser coil can cause engine vibration is by causing rough idling.
If the pulser coil is not generating a consistent signal, the engine may not run smoothly at idle. This can cause the engine to vibrate as it struggles to maintain a stable idle speed.
A faulty pulser coil can cause engine vibration by affecting the timing of the spark plug.
If the timing of the spark plug is not correct, it can cause the engine to vibrate as the combustion process is disrupted.
Another way a bad pulser coil causes vibration of a automobile or boat is that it causes lower power production from the engine.
When a boat or automobile is accelerating, it requires more power from the engine.
To make this possible, the engine burns more fuel to achieve this power demand.
But if the ignition system components like the pulser coil is faulty, the efficient combustion of fuel will not occur.
This will lead to less power production.
Due to this, vibration will occur when the engine is not able to produce the needed power.
8) Inconsistent spark timing
The pulser coil is a component in an ignition system that helps in generating the signal to trigger the spark plug to fire.
If the pulser coil is faulty, it may not generate a consistent signal.
This will lead to inconsistent spark timing.
A faulty pulser coil can cause several problems that affect spark timing.
For example, the coil may not produce a spark signal strong enough to trigger the spark plug at the right time.
This will lead to issues like misfiring or incomplete combustion leading to reduced engine performance and efficiency.
Additionally, the signal generated by a faulty pulser coil will be very inconsistent.
This will end up causing the spark plug to fire at the wrong time.
9) No spark at all
The pulser coil in an ignition system helps in generating an electrical signal that is sent to the ignition module.
This helps in triggering the spark plug at the correct time.
If the pulser coil is faulty, it can cause a variety of ignition problems including a lack of spark.
This is because when the pulser coil is not functioning properly, it can prevent the ignition module from receiving the signal it needs to create a spark.
This can cause the engine to fail to start or stall after starting.
If you are experiencing a lack of spark when starting your engine, it simply shows that the ignition system is faulty.
This can be due to faulty ignition system components like a faulty ignition coil or a faulty pulser coil.
This does not mean that it should be concluded that a bad pulser coil is the reason why an engine is not starting.
There are so many reasons why that can occur.
A bad fuel, bad spark plug and even bad spark plug cap can cause an engine not to start.
That is why it is very important to always perform a deep troubleshooting when you discover that your engine is not starting.
This will help you discover the root cause.
When troubleshooting, the pulser coil is one of the ignition system components that you have to troubleshoot.
This is because the inability of an engine to start is one of the symptoms of faulty pulser coil.
If you troubleshoot and discover that the pulser coil is bad, it has to be replaced with a good one.
This will help the engine to produce the needed power and function flawlessly when used.
