How to Troubleshoot: 1999 Ford Expedition Won’t Start

Symptoms

There are a few different symptoms that may indicate that your 1999 Ford Expedition won’t start. These include:

The engine doesn’t turn over when you turn the key in the ignition.
The engine turns over but doesn’t start.
The engine starts but dies immediately.
The engine starts but runs rough.

Causes

There are a number of different things that could cause your 1999 Ford Expedition to not start. These include:

A dead battery.
A bad starter.
A bad alternator.
A problem with the fuel pump.
A problem with the fuel injectors.
A problem with the spark plugs.
A problem with the ignition coil.
A problem with the engine control module (ECM).

Diagnosis

The first step in diagnosing why your 1999 Ford Expedition won’t start is to perform a visual inspection. This involves looking for any obvious signs of damage or wear on the vehicle. You should also check the battery terminals for corrosion.

If you don’t see any obvious problems, you can start by checking the battery. You can do this by using a voltmeter to check the battery’s voltage. The battery should have a voltage of at least 12.6 volts. If the battery’s voltage is low, you’ll need to charge it or replace it.

If the battery is good, you can then check the starter. You can do this by using a test light to check for power at the starter solenoid. If there is no power at the starter solenoid, you’ll need to replace the starter.

If the starter is good, you can then check the alternator. You can do this by using a voltmeter to check the alternator’s output voltage. The alternator should be providing an output voltage of at least 14 volts. If the alternator’s output voltage is low, you’ll need to replace the alternator.

If the alternator is good, you can then check the fuel pump. You can do this by listening for the fuel pump to prime when you turn the key in the ignition. If you don’t hear the fuel pump priming, you’ll need to check the fuel pump fuse. If the fuel pump fuse is good, you’ll need to replace the fuel pump.

If the fuel pump is good, you can then check the fuel injectors. You can do this by using a fuel pressure gauge to check the fuel pressure at the fuel rail. The fuel pressure should be between 35 and 45 psi. If the fuel pressure is low, you’ll need to clean or replace the fuel injectors.

If the fuel injectors are good, you can then check the spark plugs. You can do this by removing the spark plugs and inspecting them for damage. The spark plugs should be clean and free of deposits. If the spark plugs are damaged or fouled, you’ll need to replace them.

If the spark plugs are good, you can then check the ignition coil. You can do this by using a spark tester to check for spark at the spark plugs. If there is no spark at the spark plugs, you’ll need to replace the ignition coil.

If the ignition coil is good, you can then check the engine control module (ECM). You can do this by using a diagnostic scan tool to check for any codes. If there are any codes, you’ll need to have the ECM diagnosed and repaired or replaced.

Repair

Once you’ve diagnosed the problem, you can then repair the issue. If the problem is a dead battery, you’ll need to charge the battery or replace it. If the problem is a bad starter, you’ll need to replace the starter. If the problem is a bad alternator, you’ll need to replace the alternator. If the problem is a problem with the fuel pump, you’ll need to replace the fuel pump. If the problem is a problem with the fuel injectors, you’ll need to clean or replace the fuel injectors. If the problem is a problem with the spark plugs, you’ll need to replace the spark plugs. If the problem is a problem with the ignition coil, you’ll need to replace the ignition coil. If the problem is a problem with the engine control module (ECM), you’ll need to have the ECM diagnosed and repaired or replaced.

FAQs: 1999 Ford Expedition Won’t Start

Why won’t my 1999 Ford Expedition start?

There are a few possible reasons why your 1999 Ford Expedition won’t start. Here are some of the most common:

Dead battery: The most common reason why a car won’t start is a dead battery. If your battery is too low on power, it won’t be able to provide enough power to the starter motor to turn the engine over. You can check your battery’s voltage with a voltmeter. If the voltage is below 12 volts, you’ll need to have the battery charged or replaced.

Corroded battery terminals: Another common cause of a car that won’t start is corroded battery terminals. When the battery terminals are corroded, they can create a poor connection between the battery and the starter motor. This can prevent the starter motor from turning the engine over. You can clean the battery terminals with a wire brush and some baking soda.

Bad starter: If the starter motor is bad, it won’t be able to turn the engine over. You can test the starter motor by jumping the starter solenoid. If the starter motor doesn’t engage when you jump the solenoid, it’s likely bad and will need to be replaced.

Bad alternator: The alternator is responsible for charging the battery. If the alternator is bad, it won’t be able to provide enough power to the battery. This can cause the battery to die, which will prevent the car from starting. You can test the alternator by checking the alternator output with a voltmeter. If the output is below 14 volts, the alternator is likely 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 won’t be able to send power to the starter motor. This will prevent the car from starting. You can test the ignition switch by checking for power at the starter motor with a voltmeter. If there’s no power at the starter motor, the ignition switch is likely bad and will need to be replaced.

What should I do if my 1999 Ford Expedition won’t start?

If your 1999 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 check the battery’s voltage with a voltmeter. If the voltage is below 12 volts, you’ll need to have the battery charged or replaced.

Clean the battery terminals: If the battery terminals are corroded, clean them with a wire brush and some baking soda.

Jump the starter solenoid: If the starter motor is bad, you can try jumping the starter solenoid. To do this, you’ll need a set of jumper cables. Connect the positive jumper cable to the positive terminal of the good battery, and connect the negative jumper cable to the negative terminal of the good battery. Then, connect the other end of the positive jumper cable to the positive terminal of the bad battery, and connect the other end of the negative jumper cable to a good ground. Once the jumper cables are connected, start the good car and let it run for a few minutes. Then, try starting the bad car.

Have the alternator tested: If the alternator is bad, it will need to be replaced. You can have the alternator tested by a qualified mechanic.

Have the ignition switch tested: If the ignition switch is bad, it will need to be replaced. You can have the ignition switch tested by a qualified mechanic.

How can I prevent my 1999 Ford Expedition from not starting?

Here are a few things you can do to prevent your 1999 Ford Expedition from not starting:

Keep the battery charged: Make sure to keep the battery charged by driving the car regularly or by connecting it to a battery charger.

Avoid deep discharges: Avoid deep discharges of the battery by not letting the car sit for long periods of time without being driven.

Clean the battery terminals: Clean the battery terminals regularly to prevent corrosion.

Replace the battery as needed: Replace the battery as needed. The battery’s lifespan is typically about 5 years.

Have the alternator tested regularly: Have the alternator tested regularly to make sure it’s working properly.

Have the ignition switch tested regularly: Have the ignition switch tested regularly to make sure it’s working properly.
