In the majority of cases, the most common reason why your Ford Mustang will not start is often due to the battery, it’s either weak or dead, and you have to either charge up the battery or change it. The vehicle’s battery supplies the electricity required to start the engine, and power all the electrical components in your Ford Mustang. Symptoms of a weak or dead battery problem in a Mustang, are things like the vehicle being sluggish to crank the engine, weak or dim headlights, or a lit-up battery caution light on the dashboard. A portable jump starter allows you to jump start your car if the battery is dead without needing another vehicle. And a battery charger can help recharge a dead battery and diagnose battery issues.

Ford Mustang Alternator Problems

Signs that your Mustangs alternator may be faulty include a lit-up battery or alternator caution light on the dash, poorly lit headlights when the engine is idling, and also a whining or grinding sound from the engine while it’s running.

Ford Mustang Starter Motor Failures

Over time fuel injectors can also get clogged, so using a fuel injector cleaner like Red Line can help clean them and improve starting.

If you think it’s possibl a battery issue is the reason your Mustang has difficulty starting up, then the first thing you ought to do is inspect the battery terminals. You want them to be clean, not corroded, and firmly connected. If you discover that the terminals are in fact corroded you can attempt cleaning them with a mix of baking soda and water.

Once you have checked the battery terminals, you can check to see if the battery is just out of charge, or worse, it’s old and weak, or dead and needs to be replaced. For this, you can charge the battery in a few different ways:

If the battery charges up and works fine, great, problem solved! However, you will need to replace the battery if it’s old or weak. Otherwise, even if you charge it up enough to start the Ford Mustang, it will likely die once again in the near future. You can make use of a multimeter or OB2 scanner as a way to test the life of the battery to see if it’s worth saving or if it needs replacing. You can get a replacement car battery for your exact Ford model by visiting Amazon here, and selecting “enter a new vehicle” to filter the results for your Ford Mustang, and choose a suitable one, from a seller with great reviews.

If the alternator is what you think is the culprit, you can test it. If you can get the car to start up temporarily (you may need to jump-start the car for that), but when it’s going, let the car run, and while the engine is running, disconnect the positive terminal of the battery. It’s most likely due to a fault with the alternator if you discover your Ford Mustang dies pretty quickly when you disconnect the positive terminal. You should be aware however that this method can be risky and dangerous, and may damage the sensitive electronic elements in your Ford Mustang, so it’s necessary to consult with a reliable car mechanic locally or online, before ever trying this.

How to Identify Starter Motor Failures in a Ford Mustang
