Running out of fuel in a car can be a harrowing experience, especially if you are on a busy road or in the middle of nowhere. When your car hits the E sign, it is a warning to look for the nearest gas station. If you ignore this warning, your vehicle will start showing signs of fuel starvation, and the engine will start sputtering, followed by intermittent power surges, and eventually, a loss of power. This can cause severe damage to your car, especially to critical parts like the engine and fuel pump.

What You'll Learn
The car stops with no warning
Running out of fuel can cause severe damage to your car. A car needs fuel to function, just like the human body needs water. When a car is completely out of fuel, it will start sucking in air, which will cause issues when you try to start it up again.
When your car is about to run out of fuel, you will notice some warning signs. The blinking light on your dashboard and the gauge near the "E" mark will indicate that your fuel levels are low. Your engine light will start blinking, and your engine may start sputtering. Your car may also keep stalling, and you may experience intermittent power surges and backfiring. These are clear indications that your car is running out of fuel.
If you find yourself in this situation, it is important to pull over as soon as possible to get out of harm's way. You will then need to push your car to the nearest petrol station or call a tow truck, which can be a terrible inconvenience, especially if you are on a busy road or in the middle of nowhere.
Additionally, driving with an empty fuel tank can cause problems with your fuel injection and filter system, as it may become clogged with debris from the bottom of your fuel tank. This can damage your electric motor and may require a visit to a professional mechanic.

Fuel starvation
In cars, fuel starvation can cause the engine to sputter and surge intermittently, leading to a loss of power. It is recommended to refuel a vehicle when it hits the "E" sign to avoid these issues and potential damage to the engine.

Engine sputtering
When a car runs out of fuel, it will start sucking in air, which will cause problems when you try to start it up again. You may notice some symptoms before the car comes to a complete stop, including engine sputtering, intermittent power surges, backfiring, and loss of power. Engine sputtering can be caused by a variety of issues, and it is important to identify the root cause to prevent long-term damage to your vehicle. Here are some of the most common causes of engine sputtering:
- Fuel injectors: Fuel injectors play a crucial role in maintaining a steady spray of gas into the engine's combustion chambers. If the fuel injectors become dirty or clogged, the fuel flow will be inconsistent, resulting in a sputtering engine. Clogged fuel injectors can also cause a lean fuel mixture in the combustion chamber, leading to engine sputtering.
- Fuel filters: Over time, fuel filters can get filled with dirt and contaminants, leading to a sputtering engine. Replacing the fuel filter may resolve this issue.
- Vacuum hoses: All vehicles have vacuum hoses that create fuel pressure. If one of these hoses leaks or is damaged, it can result in a significant loss of fuel pressure, causing the engine to sputter.
- Exhaust leaks: The vehicle's exhaust system can impact engine performance. If there is an exhaust leak, harmful exhaust gases can flow back into the engine, leading to major problems, including engine sputtering.
- Catalytic converter: The catalytic converter is responsible for burning off the most dangerous elements in the exhaust gases. If it becomes clogged, the exhaust gases back up into the combustion chamber, causing the engine to sputter.
- Mass airflow (MAF) sensor: The MAF sensor monitors and controls the mix of fuel and air in the engine. If it sends incorrect data to the engine control unit, it can result in a lean fuel mixture and cause the engine to sputter.
- Oxygen sensor: The oxygen sensor measures the oxygen levels in the vehicle's exhaust system. If it malfunctions, it can send skewed information to the engine control unit, leading to an incorrect air-fuel ratio and causing the engine to sputter.
- Spark plugs and wires: Worn spark plugs and wires can cause the engine to misfire or sputter.
It is important to note that engine sputtering can be a sign of other issues with your vehicle. If the problem persists or is accompanied by other symptoms, it is recommended to consult a professional mechanic for proper diagnosis and repairs.

Fuel filter gets clogged
The fuel filter plays a crucial role in ensuring that only clean fuel reaches the engine. When the fuel filter gets clogged, the engine does not receive enough fuel, which can lead to various problems. Here are some detailed explanations and instructions regarding a clogged fuel filter:
Signs of a Clogged Fuel Filter
Firstly, it is important to recognize the signs of a clogged fuel filter. Some common indicators include:
- Misfire or rough idle: A clogged fuel filter may cause the engine to misfire or experience rough idling due to insufficient fuel supply.
- Vehicle stalling: A clogged filter restricts fuel flow, especially during acceleration, which can lead to the engine stalling, especially when idle.
- Fuel system component failure: The electric fuel pump may fail prematurely as it struggles to push fuel through the clogged filter.
- Unusual noises: Loud and sudden unusual noises coming from the fuel pump could indicate a clogged filter.
- Check Engine Light: As fuel struggles to flow through the clogged filter, it can cause low fuel pressure, triggering the check engine light.
- Acceleration issues: If your vehicle struggles to accelerate, especially uphill or when carrying heavy loads, it could be due to a clogged filter restricting fuel flow.
- Increased fuel consumption: A clogged fuel filter can cause the engine to burn more fuel as it attempts to maintain performance.
Preventative Measures and Maintenance
To prevent a clogged fuel filter, it is recommended to change the filter regularly. The general guideline is to replace the filter every 2 years or 30,000 miles, whichever comes first. However, if you frequently drive on unpaved roads or in dusty conditions, you may need to change the filter more often. Regular maintenance and replacement of the fuel filter can help avoid engine problems and save you from costly repairs.
Professional Assistance
If you suspect that your fuel filter is clogged, it is advisable to seek professional assistance. Trained technicians at service centers, such as Firestone Complete Auto Care or Jiffy Lube, have the necessary tools and expertise to diagnose and fix the issue. They can help clean or replace the fuel filter, ensuring optimal performance and longevity for your vehicle.

Fuel pump gets damaged
A damaged fuel pump can cause a range of issues with your car's performance and drivability. The fuel pump is responsible for delivering fuel from the tank to the engine, so a damaged pump can cause disruptions in this process. Here are some common issues that may arise when your fuel pump is damaged:
- Engine Misfires: The engine may sputter or misfire, especially during acceleration. This is often due to low pressure caused by a faulty fuel pump, which affects the fuel and air mixture needed for combustion.
- Difficulty Starting: You may experience difficulty starting your car, requiring extended cranking before the engine turns on. In some cases, the car may not start at all.
- Stalling or Surging: The engine may stall or surge unexpectedly while driving, caused by too much fuel being sent to the engine.
- Decreased Fuel Efficiency: There may be a significant drop in your car's mileage or fuel efficiency, indicating that the fuel pump is not delivering enough fuel to the engine.
- Sudden Loss of Power: The car may experience a sudden loss of power, particularly when accelerating or climbing hills, due to insufficient fuel being pumped to the engine.
- Whining Noise: You may hear a high-pitched whining or humming noise coming from the fuel pump area, indicating possible damage or blockage in the pump.
- Fuel Smell: You may notice the smell of gasoline inside or around your car, which could be a sign of a fuel leak or a faulty fuel pump.
It is important to note that these issues can also be caused by other factors, such as bad fuel, damaged fuel lines, or a clogged fuel filter. Therefore, it is always recommended to consult a professional mechanic for a comprehensive inspection and diagnosis to identify the root cause of the problem.
