1. Ensure the gas cap is securely tightened. This prevents fuel vapors from escaping and causing issues.
2. Turn the ignition key to the "on" position (but don't start the engine yet). This allows the fuel pump to prime and fill the fuel lines. This step is especially important if the car sat for a while after running out of gas. You might hear the fuel pump whirring for a second or two – that's normal.
3. Start the engine. It should start normally after a brief pause for priming.
If the car doesn't start after following these steps, there might be additional issues beyond simply running out of gas. You should check the following:
* The gas cap is securely on. A loose gas cap can prevent the car from starting (especially newer cars with electronic fuel pressure monitoring).
* The fuel pump is working. A faulty fuel pump is a common reason a car won't start.
* The battery is charged. If the battery was drained trying to start the car with no fuel, you might need a jump start.
* The starter motor is working. The starter motor is responsible for turning the engine. A problem with this would need mechanical attention.
* There are no other electrical issues. A blown fuse, corroded connections, or other electrical problems could also prevent the car from starting.
If the car still won't start after checking these things, you might need professional help from a mechanic.
