There is nothing more frustrating than a car that won’t start. That’s why a starting system is one of the most important parts of your vehicle. That said, an issue with your starting system can be fixed pretty easily. Especially if you own an F250 pickup truck.
F250 Starting System Fault is caused due to:
- A damaged engine control unit
- Key issues
- A faulty battery and
- A malfunctioning alternator
All these fixes need you to take a trip to the mechanic. It is essential to be well-informed on any topic before going to a repair shop. Otherwise, you open yourself up to various scams. Luckily for you, this is a complete guide to fixing a starting system.
4 Most common F250 Starting System Faults fix guide
A car doesn’t stop starting out of the blue for no reason. If one of these components is damaged, the entire system will fall apart.
#1. Key Issues– Replace Your Key
You probably already know this but you can’t start your car without your keys. Putting the key in and turning it is your car’s equivalent of grabbing a cup of coffee and starting the day. If the key malfunctions for any reason, the car simply won’t start.
The intention behind this was obviously safety concerns but it can be quite frustrating when it inconveniences the owner of the car. The possible issues include a damaged key fob, a dirty keyhole, and a broken key.
Fortunately, Ford has some excellent customer support. If you bought the car from a licensed dealer and you still have your warranty, they may replace the key for free.
If you don’t have insurance and you bought a used car, you still have the option of buying a replacement key. My only advice is to try and get it fixed by Ford themselves. Mechanics don’t know the F250 better than the ones who made it.
#2. Faulty Engine Control Unit– Swap Out The ECU
The engine control unit (ECU) as the name suggests is the component that determines the fuel and air management system in your engine. Simply put, this is the heart of your engine.
Without this component, the engine cannot perform at the optimal level. In fact, it may not even start. This computerized unit forms an integral part of the starting system. I’ve seen this as a common 2015 f250 starting system fault.
Unfortunately, not every problem is as easy to fix as the first one. If replacing the key doesn’t get your car moving, there may something wrong with your ECU. As I mentioned, this is pretty much the heart of your vehicle so without it, your car won’t work.
The ECU can rarely be repaired so your only option is to swap it out for a new one. This is a procedure that should be done by professionals so hand your vehicle over to a mechanic and sit back.
#3. Dead Battery– Recharge The Battery
Everyone knows that a battery is what powers the car. This unit turns the chemical energy in your fuel into electrical energy to power up your vehicle. Needless to say, if this component isn’t working, your car won’t find the power to turn on.
A dead battery is one of the issues that you can fix almost immediately if you have a friend with a car and jumper cables. These 4 short steps should do the trick:
- Step 1: Attach the cars’ engines with the jumper cables
- Step 2: Start the car that works
- Step 3: Try starting the car that’s having starting issues
- Step 4: If it works, disconnect the wires.
If you only need to follow this process once, there is no reason to worry. But if you find yourself needing to do this every few days, I suggest getting that battery checked out by your mechanic as soon as possible.
#4. Broken Alternator– Change The Alternator
It is easy to get the battery and alternator confused as they serve almost similar purposes. In layman’s terms, the battery creates the electrical energy and the alternator spreads this energy. It essentially continuously recharges your car.
As you can tell by now, a f250 starting system fault fix usually lies in replacing a broken component. The last component that you should consider replacing is your alternator as this is a sturdy component: it lasts 7 years easily.
After the 7-year mark though, changing it may be the exact issue you are looking at. Again, you should seek high-quality professional help for this process.
How To Pinpoint The Damaged Component?
It is vital to properly diagnose your vehicle for the best result. These 4 methods should help you properly inspect your F250.
- Using An OBD-II Scanner
This handy tool has helped car owners for generations. The DTC should help you track down the exact issue quite easily.
- Visual Inspection
Sometimes, a visual inspection may suffice. For example, a broken keyhole is hard to miss. A cool feature on the F250 is the service advance starting system fault warning light which will inform you that ECU has issues.
- Isolated Tests
This will take ages but it is the most reliable at-home test you can run. Test out each of the aforementioned components individually to see which one is really damaged.
- Go To A Mechanic
Lastly and my go-to advice is immediately head to the repair shop. Experienced mechanics can accurately locate the source of the issue and act accordingly. Just make sure you research though as scams are not uncommon.
how much does it cost to repair f250 starting system problems?
This question is one that is hard to answer. That’s because the cost varies so much.
For example, the cost of fixing 2016 f250 starting system fault alone has 4 possible values. It could be $50-250 to replace the key. Just shy of $300 to change the ECU. $20 for the jumper cables. Or you might have to spend a small fortune of $800 for a new alternator.
These costs will vary from model to model. In other words, there is no clear answer to the question, the best we can do is make estimates based on the problem and model.
Frequently Asked Questions (FAQs)
No. The F250 is one of the best heavy-duty trucks out there. You can expect this vehicle to fire up right away in most cases. In the rare circumstance that it does have these issues, you already know how easy the fixes are.
No. If your car stops in the middle of the road, you are going to be in a lot of trouble. It is not just unsafe but also irresponsible to drive a vehicle that isn’t in optimal conditions.
Yes, you can. However, I highly recommend against it. The procedures are quite complex and without experience, they are very easy to mess up. Also, injuries are quite common when it comes to auto repair. Also, it can be difficult to find parts for older models like a 2011 ford f250 starting system fault.
The F250 and most F-series trucks tend to face problems with the engine if anything. The fuel pump, fuel filter, and IWE are also components that have been known to get damaged every once in a while. However, this is a sturdy vehicle so these issues are rare.
Whether it be changing parts of your vehicle or a simple jumpstart procedure, the solution barely presents a challenge.
Do you know what poses even less of a challenge though? Timely car maintenance. Taking your car to the mechanic every once in a while will help prevent these major issues. Make sure you give your car the care it deserves.
