Symptoms of a Car Fuel Filter Gone Bad

Almost all types of vehicles with internal combustion engines come with fuel filters. Their primary function is to prevent particles present in the fuel from entering the fuel system and damaging the engine components. Over time, the fuel filters become dirty and clogged. Eventually, it will fail to filter out particles efficiently. At some point, it may even restrict fuel flow.

However, these issues do not manifest in an instant. In most cases, you will see early signs that will tell you that there is something wrong with your fuel filter. In this post, we are going to share the symptoms. This way, you will be able to get a fuel filter repair service and address the issue promptly.

The Engine Fails to Start

When your fuel filter becomes clogged with grime, you won’t be able to start your vehicle. The fuel pressure may attempt to push things forward to the engine. However, since the contaminants have not been filtered out, the gasoline will become too thick. If you notice the engine cranking but not starting, then it is high time you checked the condition of the fuel filter.

The Check Engine Light Illuminates

It can be worrying to see the Check Engine Light illuminating on your dashboard. However, in some cases, this does not necessarily mean that your engine is malfunctioning. Sometimes, it is just telling you that there is something wrong with your fuel filter. There are vehicles with sensors that monitor the overall fuel system’s pressure. So, when your fuel filter becomes clogged, the pressure will drop. Of course, the sensor will detect this, prompting the Check Engine Light to illuminate.

That said, there is still a wide range of issues that may set off the Check Engine Light. As such, it is best that you bring your car to a service center when you see it illuminating on your dashboard. A technician should be able to use computer scanning to determine the specific problem.

The Engine Starts to Idle Roughly

Your tachometer may also tell you that you need a fuel filter repair service. While your vehicle is stopped, check if the tachometer is displaying erratic readings for the engine speed. Keep in mind that the normal idle RPM of a car is somewhere between 400 to 800 RPM. If your tachometer shows figures below that while you are idling, then it may be time to replace your fuel filter.

The Engine Wavers During High-Load

Does your engine hesitate when you are trying to overtake another vehicle or when you are driving uphill? If so, then it is likely that your fuel filter is clogged. This situation can be downright scary and dangerous, especially when you need a sudden burst of acceleration or power.

You can trace the issue back to a problem with the inline fuel filter. It is worth noting that your engine needs more fuel whenever you step on the gas pedal to accelerate. So, when the fuel filter is clogged, the engine does not receive enough fuel. If it does get fuel, what it receives is not potent or pure.

The Engine Dies Frequently

Your fuel filter may be clogged if you notice your engine dying from time to time. Your vehicle will start like the usual. However, once you start driving it, you will notice a loss of power. When you stall like this, your engine does not receive the right amount of gas it needs. It is likely that this issue is caused by a clogged fuel filter.

If you see these signs, make sure you bring your car to a mechanic as soon as possible. Keep in mind that a dirty fuel filter can lead to bigger issues and driving hazards when ignored.
