Why 2004 Ford Expedition Won’T Start

Dead battery

The most common reason for a car not starting is a dead battery.
If the battery is too low, the starter motor will not have enough power to turn the engine over.
To check the battery, use a voltmeter to measure the voltage. A healthy battery should have a voltage of at least 12.6 volts.
If the battery voltage is below 12.6 volts, it will need to be replaced.

Corroded battery terminals

Corroded battery terminals can also prevent a car from starting.
The corrosion can create a poor connection between the battery and the starter motor, which will prevent the starter motor from turning the engine over.
To clean the battery terminals, use a wire brush to remove the corrosion.
Once the terminals are clean, apply a thin coat of dielectric grease to prevent future corrosion.

Bad starter motor

If the starter motor is bad, it will not be able to turn the engine over.
To test the starter motor, use a test light to check for power at the starter solenoid. If there is no power at the solenoid, the starter motor is bad and will need to be replaced.

Bad alternator

The alternator is responsible for charging the battery.
If the alternator is bad, it will not be able to charge the battery, which will eventually lead to a dead battery.
To test the alternator, use a voltmeter to measure the voltage at the battery terminals. With the engine running, the voltage should be between 13.5 and 14.5 volts. If the voltage is below 13.5 volts, the alternator is bad and will need to be replaced.

Ignition switch problem

The ignition switch is responsible for sending power to the starter motor.
If the ignition switch is bad, it will not be able to send power to the starter motor, which will prevent the car from starting.
To test the ignition switch, use a test light to check for power at the starter solenoid. If there is no power at the solenoid, the ignition switch is bad and will need to be replaced.

FAQs: 2004 Ford Expedition Won’t Start

Why won’t my 2004 Ford Expedition start?

There are a few possible reasons why your 2004 Ford Expedition won’t start. Here are some of the most common causes:

Dead battery: The most common reason for a car not starting is a dead battery. If your battery is more than three years old, it’s a good idea to have it tested to make sure it’s still in good condition. You can have your battery tested at most auto parts stores.

Corroded battery terminals: Another common cause of a car not starting is corroded battery terminals. Corroded terminals can prevent the battery from properly connecting to the car’s electrical system, which can prevent the car from starting. You can clean the battery terminals with a wire brush and some baking soda and water.

Bad starter: If your starter is bad, it won’t be able to turn the engine over. You can have your starter tested at most auto repair shops.

Bad alternator: If your alternator is bad, it won’t be able to generate enough power to keep the battery charged. This can eventually lead to a dead battery, which will prevent the car from starting. You can have your alternator tested at most auto repair shops.

Improper spark plug gap: If the spark plugs in your car are not properly gapped, they won’t be able to create a spark strong enough to ignite the fuel in the engine. This can prevent the car from starting. You can have your spark plugs gapped at most auto repair shops.

What should I do if my 2004 Ford Expedition won’t start?

If your 2004 Ford Expedition won’t start, here are a few things you can do:

Check the battery: First, check the battery to make sure it’s not dead. You can do this by turning on the headlights and seeing if they come on. If the headlights don’t come on, the battery is probably dead.

Check the battery terminals: If the battery is not dead, check the battery terminals to make sure they are not corroded. Corroded terminals can prevent the battery from properly connecting to the car’s electrical system, which can prevent the car from starting.

Try jumping the car: If the battery is not dead and the battery terminals are not corroded, try jumping the car. To jump the car, you will need another car with a working battery. Connect the positive terminal of the donor battery to the positive terminal of the dead battery. Connect the negative terminal of the donor battery to a good ground on the dead car. Start the donor car and let it run for a few minutes. Then, try starting the dead car.

Have the car towed to a mechanic: If you have tried all of the above and the car still won’t start, it’s time to have the car towed to a mechanic. A mechanic can diagnose the problem and fix it.
