Fuel System Cleaning Cost – What You Need To Know!

Fuel System Cleaning Cost – What You Need To Know!

Over time and after months of use and driving your vehicle, you are going to have to get some cleaning done on your fuel system to ensure it runs properly and safely for many more years to come. Your fuel system can get clogged and become dirty over time, causing other parts of your car to misfire and work incorrectly if you do not fix this issue. 

Auto Repairs Are EXPENSIVE


Knowing how much the fuel system cleaning cost will be for your car can determine the best method on how to proceed. We need to go over a few key issues and components of the fuel system to make the best decision about if you are willing to spend the average amount on the fuel system cleaning cost for your car. 


Having a clean fuel system can provide many benefits. We will go over the benefits of having a clean fuel system, the process of fuel system cleaning, and the cost of fuel system cleaning, which generally runs on average at about $80 for the entire fuel system cleaning to be done. 

Car Fuel System Function


The function of the vehicle fuel system in your car is to store the fuel safely and supply the proper amount of fuel to the engine when needed. The engine intake system is where the fuel is mixed with the right amount of air, atomized, and then vaporized, in that order specifically.


After this process occurs, the air and fuel mixture will be compressed within the engine cylinder and then ignited to produce ample energy or power to let the vehicle run. Fuel systems change depending on what car you have and what engine you have in your vehicle. 

Car Fuel System Mechanism 

However, all systems are the same in one aspect – they must supply enough fuel to the combustion chamber and control the amount of fuel supplied with the proper air ratio. Without the proper ratio of air to fuel mixture, the fuel system will not work properly.


After this, the fuel is stored in the fuel tank to be used consistently throughout your vehicle’s driving, when the fuel pump draws fuel from the tank. The fuel then travels through the fuel lines, which must be clear during the fuel system cleaning, and then delivered through a fuel filter to the fuel injectors. The fuel filter is a key process in the fuel system cleaning process since it has to filter out the correct amount of fuel and any debris or particles within the liquid. 


When the fuel is delivered, the laser conditions required for providing complete combustion within the fuel system are atomization and the fuel’s spray pattern. Atomization can only be accomplished correctly by an injection of pressure, which occurs with the diameter of the holes in the injector. 

Faulty Fuel System Symptoms

There are a few basic symptoms on any vehicle fuel system that show signs of wear and deterioration and can let you know it is time to finally fix your fuel system and have it cleaned, despite the fuel system cleaning cost. If you do this, even if it costs a lot of money, you will be saving thousands in the long run if you initially pay for the fuel system cleaning cost. 

  • Sputtering or Shaking

The symptoms are the engine’s difficulty, like a sputtering or shaking when you try to turn on the engine. 

Car Shaking Instances

There are various instances in which your car might be shaking while you’re in the vehicle. One common instance of when your car would shake is while you are idling. The car shaking occurs when you are sitting still and not moving on the road, which typically signals some type of engine issue. Your car will usually be vibrating, and your engine will be shaking, causing you to look at the overall fuel system cleaning cost.  


The next instance is your car shaking every time you accelerate. When you press down on the gas pedal to go quicker, your car begins shaking. The car shaking while you accelerate typically due to a problem with the engine mounts or suspension system. Engine mount problems will cause the engine to begin shaking while you’re speeding up. 

Car Shaking Causes

If too many parts become worn out, or just the right combination of parts, it can cause shaking in your car. If your axle is somehow damaged, this can cause vibrations throughout your car, causing it to shake while driving and get worse while driving quicker. The axle on your vehicle can get bent during minor accidents, driving over potholes, or hitting something on the road. If you notice these causes of your car shaking and vibrating, you have to look into the fuel system cleaning cost. 

  • Hesitating During Acceleration

The second sign is a slow or hesitancy felt during acceleration, meaning it takes longer to get up to the right speeds, which you will often see during highway driving. 

  • Stall While Driving

The third sign of deterioration of the fuel system and the necessity for fuel system cleaning cost is that you might stall while driving, which can be very dangerous if not taken care of since you could stall out in the middle of a moving road. 

Fuel Pump 

The second reason your car stalls while driving is that there is something wrong with your fuel pump. The first time you will notice a problem with a fuel pump is that the car can stall while driving and cause you not to restart the car. The fuel pump might show signs of why the car stalls while driving, like a slight buzzing noise while it is running. 


If you do not hear any noises while using the fuel pump, you likely have a bad fuel pump and need to look into the fuel system cleaning cost. 


There are clear signs that your fuel pump is going bad and can be the reason why your car stalls while driving. One sign that your fuel pump is damaged is that the car will sputter at high speeds since the engine can struggle while supplying a constant stream of fuel to the engine at the right pressure. 


In addition, the rising temperature of the fuel pump can cause the heat to rise, the car to stall, and the fuel pump motor to be having problems. If you notice any of these symptoms, you need to look into the fuel system cleaning cost. 


In addition, the fuel pressure gauge shows how much fuel is getting to the engine, showing how much fuel pressure should be exerted when the pump is operating properly, and anything less than that is a sign that your fuel pump needs immediate attention and can cause your car stalling while driving. 

  • Intermittent Power Loss 

The fourth symptom is an intermittent power loss, meaning your vehicle can shut off during driving, causing all electronics and the engine itself to stop working. 

Bad Battery

A bad battery is one of the most common reasons why your car will stall while driving. The car battery is the rechargeable battery that supplies the necessary electrical current to a motor vehicle, with the main purpose to feed the starter, which in turn powers and starts the engine to run your car. If the battery is dead, your car will not start. Furthermore, you might not even know that when your battery is undergoing damage or going back, it can also cause the car to stall while driving. 


When your battery is not putting forth enough power to your car, the alternator must work even harder to keep the engine running and power the car to the right performance. When the alternator has to work too hard to turn on the engine, it can overstress the engine in the car and cause it to work harder. The engine’s stress in your car can cause the car to stall while driving, and the need to look at the overall fuel system cleaning cost. 

  • Dashboard Lights Turn On 

The fifth symptom is that the dashboard lights may turn on, showing there is an issue in your vehicle. It usually is the Check Engine Light illuminated on your dash, showing the fuel system cleaning cost will be more plausible than a damaged engine. 

  • Rough Idling

The sixth sign that your fuel system cleaning needs to occur sooner rather than later is rough idling with your engine. Rough idling can mean anything from a minor problem to a severe issue. The average sedan can have an idle speed of anywhere between 600 to 1000 RPMs, so you need to check this number out if your car feels damaged or idling incorrectly. 

Causes of Engine Rough Idling

A few reasons for a rough idle is the incorrect set idle speed, damaged spark plugs, an electrical parts failure, oxygen sensors are dirty, and the airflow sensor is not working, or – as we are talking about now – the fuel filter or fuel pump is clogged. 


You can tell your vehicle is having a rough idle when cold if there is a shaking and bouncing

sensation in the vehicle, and you feel like the car is vibrating too much while your car is not moving. Although some cases are less severe than others, the rough idle is usually pretty identifiable by both the driver and passengers.


In addition to the vibrations, you might also notice strange sounds when the car is running rough idle when cold. Along with the strange sounds coming from your engine and under your hood, there might be an inconsistent engine RPM while driving and accelerating. Typically, a healthy vehicle will have a smooth RPM that stays at a consistent level of around 1,000 revolutions. If your vehicle is going too far below this line or moving too far above, then you might be dealing with a rough idling issue. 

  • Excessive Engine Smoke

The seventh sign that your fuel system cleaning cost is immediately necessary is excessive engine smoke. 

Cause of White Smoke from Engine

CondensationIf you live in a certain climate, especially colder climates, condensation can build up on your vehicle’s windows and internal parts. Suppose it is cold outside, and you notice white smoke from the exhaust on the startup. In that case, this is probably a minor issue that just happens due to the circumstantial situation, but not because of any internal problem.


Coolant LeakIf you see white smoke from the exhaust on startup after the engine has already warmed up and you have been driving for a few minutes, then this is a sign you could have a coolant leak in one of the pipes or engine in your car. If the coolant leaks, the engine will not cool itself or provide the proper lubrication for the parts, leading to overheating and an excess reaction.


You might have a coolant leak because there could be cylinder head damage or internal engine issues. The cylinder head is above the cylinders on the cylinder block, housing components like the intake and exhaust valves to help circulate the necessary coolant. 


Valve Seal LeakIf you find that your valve seals are leaking or piston rings are damaged, this can lead to white smoke from the exhaust on the startup. If this is the case, the oil will leak into the combustion chamber, where the oil will mix with the fuel and disrupt the precious air to fuel mixture ratio within the internal combustion engine. The oil leaking will cause white smoke from the exhaust on startup.

  • Fuel Odors

The eighth sign of fuel system damage is noticeable fuel odors, whether from fuel or gasoline itself, coolant leaking, other liquids leaking, or odors coming from combustion processes, like burning smells. 

Cause of Burning Smell

The fuel odors and burning smell can be a warning sign of transmission failure – you can tell if the transmission is bad, you can notice a burning smell in your car. When you notice a burning smell coming from under the hood or while driving in your car, you need to visit an auto shop right away. This odor is often a sign that your transmission is overheating or the transmission fluid is too old and filled with debris. 


A second warning sign of the transmission failure and how to tell if the transmission is bad is that you can notice a burning smell in your car. When you notice a burning smell coming from under the hood or while driving in your car, you need to visit an auto shop right away. This odor is often a sign that your transmission is overheating or the transmission fluid is too old and filled with debris. 

  • Decreased Fuel Economy 

The ninth and final sign that your fuel system cleaning cost needs to happen right away is decreased fuel economy or lower miles per gallon than normal for your vehicle. 


Noticing the signs of a faulty fuel system and other mechanisms in your car can help give you an average idea of what you may spend on the overall fuel system cleaning cost for your specific vehicle.
