Ford F-350 Battery Issues

In the majority of instances, the most common reason why your Ford F-350 won’t start is often because of the battery, it’s either dead or weak, and you need to charge your car’s battery or replace it. The car’s battery stores the power required to start the engine, and power all the electrical parts in your Ford F-350. Symptoms of a bad battery problem in a F-350, can be things like the car being slow to crank the engine, poorly lit headlights, or a lit-up battery warning light on your car’s 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 F-350 Alternator Problems

The alternator is responsible for charging the battery from the engine while the vehicle is running. A faulty alternator can certainly stop your Ford F-350 from starting as it will not have the ability to charge up the battery, from the engine, so it will drain all the way down till it’s completely drained and you don’t realize it until you get into your beloved F-350 and it refuses to start. Symptoms that your F-350s alternator may be faulty can be a lit-up battery or alternator warning light on the dashboard, dim headlights when the engine is idling, and also a whining or grinding sound from the engine while it’s running.

Ford F-350 Starter Motor Failures

The starter motor handles turning the engine over (cranking) when you start your Ford. If the starter motor is failing in some manner then the engine won’t crank, and your F-350 can’t start. You can tell if your starter motor has a problem or not often by listening, if you hear a clicking noise when you turn the key or a grinding sound throughout the startup, or your car starts up but only intermittently, then the starter motor may very well be the problem.

Ford F-350 Fuel System Complications

Now we’re not talking about when you just run out of gas here, but the fuel system itself having problems. Your Ford F-350 uses a combustion engine, andfor that reason to start and run, it requires a proper mix of fuel and air. If your F-350 issues are due to a faulty fuel system, this could be a clogged fuel filter or a damaged fuel pump relay, which could indicate the engine might not be receiving the fuel it needs to get the vehicle started. Over time fuel injectors can also get clogged, so using a fuel injector cleaner like Red Line can help clean them and improve starting.

Ford F-350 Electrical System or Wiring Problems

Ok, so that image is a joke, but all the same, today’s modern Ford F-350s rely greatly on electronic components, which can mean there are lots of things that can potentially break. Even in an older vehicle, you can still have fairly normal problems such as blown fuses, spark plug problems, a faulty ignition switch, or a damaged sensor, and more. These can be a few of the various electrical reasons that your Ford F-350 will not start. Symptoms of a circuitry or electrical problem can vary widely but can often include the engine not cranking, or your F-350 can start but just intermittently or various alert lights are lit up on the dashboard. To properly diagnose and repair these kinds of issues, you will need the abilities of a skilled car mechanic in your area or online.

Solutions & Repair Tips

If you think it’s possibl a battery problem is the reason your F-350 has difficulty starting, then the first thing you must do is inspect around the battery and check the battery terminals. You want them to be clean, not corroded, and securely connected. If you find 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 weak or old. Otherwise, even if you charge it up enough to start the Ford F-350, it will probably die once again in the not so distant future. You can make use of a multimeter or OB2 scanner as a way to test the life of the battery to find out 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 F-350, and choose a suitable one, from a seller with great reviews.

If you can get the car started temporarily (you may need to jump-start the car for that), but once it’s going, let the vehicle run, and while the engine is running, disconnect the positive terminal of your car’s battery. It’s most likely due to a fault with your car’s alternator if you discover your Ford F-350 dies pretty quickly when you disconnect the positive terminal. However, be warned this test can be risky and dangerous if you don’t know what you’re doing, and might damage the delicate electronic parts in your vehicle, so its best to consult with a reliable mechanic in your area or online, before ever trying this.
