Why Your Car Won’t Start: A Troubleshooting Guide
Itâs early morning, and youâre just getting ready for work. You take your morning coffee in perfect silence, watching gentle rays of sun flutter in through the barely open blinds. Itâs cool, and thereâs a light layer of frost on the grass, but you arenât cold. What a perfect morning! Truly, this is the best possible beginning to the rest of your life from this point out.
And then it happens.
You slip into the driverâs seat to start your vehicleâ¦ only to find out that your car won’t start. Wow. What a way to top off an otherwise glorious start to your day!
Unfortunately, this is a familiar scene to a large number of people. It seems like your car never acts up until the worst possible moment, right? I think we call that âMurphyâs Lawâ. Yâknow, the idea that whatever can go wrong will go wrong. Luckily you read the Motorful blog. This means that you have front row access to the latest and greatest information around. Weâre here to serve up a hot plate of knowledge so that whatever happens youâll be ready. Today weâre going to explore the different reasons your car may not be starting, and how to go about remedying the situation.
A car that wonât start can be a scary thing to behold. There is nothing more frightening than the realization that youâre stranded. After all, these things rarely happen in a convenient place. Maybe youâre out running errands, or youâre traveling to see family. Whatever the case it is always a chilling feeling to realize that your engine isnât responding. You need to figure out your next move- and fast. The earlier scenario is definitely the best one, but we want you to be ready in any situation that comes your way. So, keep reading to find out more about this problem and, more importantly, how to go about fixing it.
Think Horses, Not Zebras
First of all, donât panic. Your car not starting might not be the end of the world. Unless youâve been putting off repairs and youâre panicking because of that, of course. Youâll probably have a good idea before you begin of whether or not itâs a quick fix or youâre in for a tough time. That being said, there really are so many simple cases, with simple fixes. It would be silly to jump to conclusions! Weâre going to explore a few of these more casual causes before we jump to the more concerning signs.
Lights On, But Nobodyâs Home
You must have known this would make it on our list! Leaving on a light, whether itâs a dome light or your headlights, can spell disaster. Everybody knows this, but itâs rather simple to do. Thatâs why new cars come with lights that automatically turn on and off. Essentially what happens is that the battery is supplying energy to your car, but that stockpile of energy is not being replenished. This means when you go to turn your car on it wonât start. This is easily the most common, and simplest to fix, of all the problems.
Youâre going to want to check a couple of things before you start. First, check to make sure that the battery isnât dirty, and that all the connections are secure. Once youâve ruled out both of those issues itâs time to get down to businessâ¦ and find somebody to jumpstart your car. This can be easier said than done, but most people are willing to lend a hand if you have car trouble. Itâs that common thread of decency that keeps all of us connected! This is also why you should always carry jumper cables with you.
There is another solution that puts you back in the driverâs seat that much quicker, too. Portable car battery chargers are essential to anybody who owns a car. Meaning, you! With one of those bad boys, you can easily have your car back on in no time. It also skips the entire process of being a sitting duck and waiting for a friend, or hoping a stranger notices and takes pity on you. Regardless of the method you choose, this is the best case scenario.
Corrosion On The Cables
Remember how we told you to check your battery for grime build-up? Weâre going to explore that topic a little bit more. As it turns out the cable that connects the battery to the starter is the thickest cable in the electrical system of your car. This cable carries the most current, as well. Itâs because of this that itâs so susceptible to corrosion. If this cable becomes compromised in any way youâll have a pretty tough time getting your car to start!
Still, itâs not time to panic yet. After all, this is on our âsimple fixâ list! That means youâll be able to get your wheels spinning again in a snap! If youâre prepared (and with all of our guides, thereâs no reason not to be!) then you have a toolkit on you. In this toolkit, you should find a wire brush. Hint: Notice how we say âshouldâ. If this doesnât apply to you, then go out and get that kit, and a wire brush. Itâs a small purchase compared to the time youâll waste sitting around otherwise. When you can fix it yourself, you should!
Remove each end of the starter cable. One is, of course, attached to the battery. The other is, naturally, attached to the starter. Take your wire brush and give the connections a hardy scrubbing. Get it squeaky clean, and reconnect! Donât forget to clean the battery posts, too, for good measure.
The above can also be true for your grounding cables! A poor connection can be the root of your car starting woes. Use the above method on your grounding cables if the starter cable doesnât seem loose or overly corroded.
A Stuttering Starter
Starters are another common origin of start-up problems. This is probably pretty self-evident because of the name itself! If you notice that your car is taking longer to start, itâs not turning over, or itâll start but only after a couple tries, itâs probably the starter. You need to get it replaced, but you do have a little time to work with. Donât let it go for too long, however, or you risk getting really stranded and that fix isnât as simple as charging a dead battery! Letting your starter completely wear out is absolutely something to avoid. So, while it isnât right-this-minute urgent, youâre going to want to make an appointment with your mechanic as soon as you can.
A Technological Mishap
New cars are fantastic, sleek visions of the future. Itâs amazing what they manage to come out with every year. Some of these handy features made for convenience, however, can provide the opposite. Some steering wheels come with an anti-theft feature which locks the wheel in place. This means that if the wheel pushes against the pawl it will keep the car from starting. When you remove your key this locking system can ensure that your car wonât move without that specific key, which is great! But it isnât so great when youâre the apparent thief itâs trying to keep out. Try giving the wheel a little shove to the left, and see if you can get it working.
Another weird tip that can work is checking the security system of your vehicle. If youâve had a new key made for your vehicle it might be at fault! In new cars, the car must be started by the correct key. If the keyÂ has not been programmed correctly it will not start your car. This can be an incredibly distressing situation since most people think that there must be something very wrong. When you check absolutely everything and it all checks out, you may think that the problem must be beyond you. Itâs these dumb, little tidbits of knowledge that we hope will carry you through these situations and save you a buck or two!
So, youâve tried all the tricks above, but youâre still coming up with empty hands? Time to get a little more technical, then. Unfortunately, itâs probably going to be a deeper rooted problem that only an experienced technician can fix. Note that this isnât always the case. There are some other silly things (no gas, remote starter woes, etc.) can be at fault. From here out we forget these little problems and move on to the more worrying points of fault.
Interrupted Fuel Injection
The purpose of fuel injectors is pretty simple. They supply the engine with gasoline so that the combustion process, which powers the car, can happen. These injectors can be prone to breaking or cracking if they are not replaced in a timely manner. The general rule is every 100,000 miles. Thatâs a pretty long time! Itâs because of this that you may just forget about them at all, especially if you arenât a technical person yourself. If your fuel injectors need to be replaced, you need to see a professional. This is a job that can only be done by somebody with the right tools, the right knowledge, and the right experience.
Can Crank, Canât Start
As a general rule if your car is turning over but not starting there is a bigger problem at play. Once youâve covered all of the bases you should have an answerâ¦ and if not, itâs time to bring in the big guns. You can rest assured that your mechanic will find whatever the cause is, no matter how complicated. Youâll need an official diagnosis, and probably some specific tools, to get to the bottom of this problem. Unfortunately, this is really the end of the line, which is why weâve topped off this list with such a general, sweeping issue. Once youâve worked your way to this point it becomes time to throw in the towel.
Itâs a soft, gorgeous morning. The air smells like a promise, and you can feel the heat of the sun already. Perhaps youâre sipping coffee on your porch and enjoying the moment. Or, youâre sitting inside, lounging leisurely in the calm, still twilight before your commute. Once youâve soaked in the serenity you need to get through your day you make your way outside. You get in your car. You slide the key into place.
And thatâs when it happens.
