Causes of Car Barely Starting After Getting Gas
There are several reasons why your car might barely start after getting gas. Let’s explore some of the most common causes:
Fuel Pump Issues
The fuel pump is responsible for pumping fuel from the tank to the engine. If the fuel pump is malfunctioning or worn out, it may not be able to provide the necessary pressure to start the engine. This can cause the car to barely start or stall frequently. Signs of a faulty fuel pump include:
- A clicking sound when you turn the key
- A slow or erratic fuel pump
- Difficulty starting the engine
Fuel Filter Issues
The fuel filter is responsible for cleaning the fuel before it reaches the engine. A clogged or dirty fuel filter can restrict fuel flow, making it difficult for the engine to start. Signs of a clogged fuel filter include:
- Difficulty starting the engine
- Stalling or sputtering
- Reduced engine performance
Fuel Line Issues
Fuel lines are responsible for carrying fuel from the tank to the engine. Cracked, damaged, or clogged fuel lines can restrict fuel flow, making it difficult for the engine to start. Signs of fuel line issues include:
- Difficulty starting the engine
- Stalling or sputtering
- Reduced engine performance
Spark Plug Issues
Spark plugs are responsible for igniting the fuel-air mixture in the engine. Worn out or fouled spark plugs can cause the engine to struggle to start. Signs of faulty spark plugs include:
- Difficulty starting the engine
- Stalling or sputtering
- Reduced engine performance
Idle Air Control Valve Issues
The idle air control valve regulates the air-fuel mixture when the engine is idling. A faulty idle air control valve can cause the engine to struggle to start. Signs of a faulty idle air control valve include:
- Difficulty starting the engine
- Stalling or sputtering
- Reduced engine performance
Diagnosing the Issue
Diagnosing the issue is crucial to determining the cause of the problem. Here are some steps to help you diagnose the issue: (See Also: Car only Starts When Putting Gas in Throttle Body? Troubleshoot Now!)

Next, check the fuel filter for any blockages or damage. A clogged fuel filter can restrict fuel flow, making it difficult for the engine to start. Check the fuel filter regularly and replace it as needed.
Check the Fuel Pump
Check the fuel pump for any signs of malfunction or wear. A faulty fuel pump can cause the engine to struggle to start. If you suspect a faulty fuel pump, have it replaced by a professional mechanic.
Check the Spark Plugs
Check the spark plugs for any signs of wear or fouling. Worn out or fouled spark plugs can cause the engine to struggle to start. Replace the spark plugs as needed.
Check the Idle Air Control Valve
Check the idle air control valve for any signs of malfunction or wear. A faulty idle air control valve can cause the engine to struggle to start. If you suspect a faulty idle air control valve, have it replaced by a professional mechanic.
Fixing the Issue
Once you’ve diagnosed the issue, it’s time to fix it. Here are some steps to help you fix the issue:
Replace the Fuel Filter
If the fuel filter is clogged or damaged, replace it with a new one. Make sure to check the fuel filter regularly to avoid any future issues.
