7 Reasons Your Car Won’t Start After Getting Gas

EVAP purge control valve Failure

Your car won’t start after getting gas can be a common problem, but it can be easily fixed.

One of the main reasons this happens is due to a faulty EVAP (Evaporative Emission Control) purge control valve. This valve is responsible for controlling the air pressure in your gas tank. When you fill your tank with gas, the air pressure builds up and needs a place to escape.

If the valve is stuck open, the excess air pressure is pushed directly into the intake manifold, causing too much fuel to enter the combustion chambers when you start your engine. This can make your car difficult to start.

How To Fix It

To fix this, you need to check for any leaks or clogs in the EVAP system and make sure the valve is functioning properly.

This information will help you get your car running again after a trip to the gas station.

Clogged Fuel Filter

One of the most common reasons why your car may not start after refueling is a clogged fuel filter. The fuel filter is an important component in your car’s fuel system that helps remove impurities such as dirt, water, and other contaminants from the fuel before it reaches the engine.

Over time, the fuel filter can become clogged, preventing fuel from flowing freely to the engine. This can result in poor engine performance, reduced power, and difficulty starting your car.

How To Fix It

To fix this issue, you will need to replace the fuel filter. The frequency of replacement depends on your car’s make and model, but most cars need a new fuel filter every 20,000 to 30,000 miles.

To prevent clogged fuel filters, it’s important to use high-quality fuel and follow the recommended maintenance schedule for your vehicle. If you notice any issues with your car’s performance or starting, be sure to check the fuel filter and have it replaced if necessary.

Corroded or Dead Battery

Another reason your car won’t start after getting gas is due to a dead battery or loose battery connections. The battery provides the power needed to start your car and it typically lasts between 3-5 years.

Signs that your battery is starting to fail include dimming lights or trouble with car accessories.

How To Fix It

To fix battery problems, make sure the battery connections are tight and clean any corrosion with a baking soda solution. If the battery is dead, jump start the car or replace the battery if necessary.

If your battery is dead or the connections are loose, your car won’t receive the power needed to start, so be sure to check these things first if your car won’t start after filling up with gas.

Alternator Failure

The alternator is a critical component of your vehicle’s electrical system.It produces electricity and stores any surplus in the batteries, so your car can start right away. It also powers other electrical features such as the headlights, windshield, stereo, and more.

The alternator is responsible for charging the battery. If your battery is fine but your alternator is not working properly, it could be because the accessory motor belt is broken or loose.

If your starter takes a long time to start, the headlights are blurry, and a warning light comes on, the alternator’s power is weak.

You can use a multimeter to check the alternator’s condition. First, turn off the engine and test the battery voltage.

The voltage level should be between 12.5 and 12.8 volts. Next, start the engine and take another reading. The reading should show a significant increase compared to the previous reading. If there is no significant increase, it means it’s time to replace the alternator.

Poor Starter Motor Or Circuit

If the starter motor fails, the engine won’t crank when you try to start the car. The starter motor is activated when you turn the key in the ignition. If the starter motor is not working, you may hear a clicking sound when you turn the key.

This is a sign that the starter motor is the problem and needs to be repaired or replaced. If you are experiencing difficulty starting your car, it’s important to get it inspected by a mechanic as soon as possible to determine the cause of the problem.

Defective Fuel Pump

The fuel pump is located in the gas tank and is designed to run at cooler temperatures. If the fuel level in the tank drops too low, it can cause the pump to overheat and become damaged.

The fuel pump is crucial for delivering gas to the engine, and if it is not functioning properly, you may experience symptoms such as sputtering while driving at high speeds, a whining noise coming from the tank, or stalling of the vehicle.

To determine if the fuel pump is the issue, you need to check the pressure using a gauge. This can be a complex process, and replacing the fuel pump can also be challenging best done by a professional mechanic.

To prevent problems with the fuel pump, it’s important to maintain proper fuel levels and keep your car’s fuel system well-maintained.


Spark issues

Spark plugs are important parts of a car engine that help start the engine. They create a spark that ignites the fuel and air mixture in the engine. If the spark plugs get dirty or stop working properly, the engine might not run smoothly and may have trouble starting.

However, spark plugs are not the only parts of the ignition system. There are also spark plug wires, an ignition module, and electrical circuits and switches that can cause problems.

To keep your car running smoothly, it is important to replace the spark plugs according to the schedule recommended in the owner’s manual. This will help prevent any issues with the ignition system and keep your car running smoothly.

Faulty Security System

Some vehicles have an engine immobilizer as part of their anti-theft security system. This system can cause problems if it becomes damaged or if its chip fails. If this happens, it may prevent your car from starting or running properly.

If you’re not sure what’s causing the issue, look for a warning light on your dashboard. This can give you an idea of what’s wrong. You can also run a diagnostic scan to get more specific trouble codes. Your vehicle’s owner’s manual can be helpful in this situation.

However, if you don’t have the proper equipment, you won’t be able to fix the problem yourself. In this case, it’s best to take your car to a dealer for repair. They will have the tools and expertise to diagnose and fix the problem.
