The Battery
The most common reason is the battery if your car won’t start but has power. Let us break it down to the core.
Vehicles nowadays tend to be dependent on electronics, and some even require a certain voltage to start. If your car is facing issues with its battery, your starter motor could be winding the engine over, which is why there would not be enough voltage to start the engine properly or even at all.
The car won’t start but has power, and you suspect your battery? How can you be sure? Let us now look into the signs one should look for to ensure it’s the engine’s battery that is at fault.
The first thing you want to do is insert the key into the car and then turn it. Notice the dash lights; are they bright? If they aren’t as they usually are, it’s probably the battery causing the same. Try turning the key even further; do they dull even more significantly? This can be caused due to a worn-out or dirty battery terminal. Why does this happen if the car won’t start but has power?
Well, this corrosion happens because of material build-up around the terminals. This makes them less conductive and thus receive and transmit reduced charge, which may fail to provide the needed boost to the engine to start and function properly.
My car won’t start but has power. Could it be the battery? To investigate, try this detective-like method: flick on the headlights to their low beam setting and rev up the engine.
Observe the headlights’ performance as you do. Do they exhibit a mysterious, unusual dimming? If so, it’s likely the battery has been drained of its life force.
Fear not, though, as jump-starting your trusty steed might be the solution—just be cautious to perform the ritual correctly, or you risk harming your car’s delicate electronics. Heed this important mantra: the red positive lead must embrace the positive terminal, while the black negative clamp finds solace in the designated metal connection.
Keep your car’s sacred tome—it’s manual—close at hand. Now, let us delve into the realm of portable jump packs. These handy gadgets have found favor among many, but do ensure that their leads boast anti-spike protection.
For both your safety and that of your mechanical companion, take care when wielding these powerful tools.
Why won’t my car start, but I have power? It is not winding over as it should? Could it be the battery? There are high chance that it is. Even if your battery looks in perfect shape and is charged, you should get a professional to test it as soon as possible. If left unattended for a prolonged period of time, this issue can cause more serious and expensive issues.
Reasons Why
Will your car won’t turn over but has power? Let us finally look into an objective list of potential reasons why a car won’t start but has power. Cross-check the following options to find the one that best suits you and your vehicle’s situation:
Faulty Starter Motor
What is a starter motor? It is the component of the car which is bolted to the engine and works with the flywheel to start the car. When engaged, the crankshaft spins, and then it gets the things to move in the engine.
If your starter fails to function properly, the engine fails to receive the jump it requires. You will also not hear anything when the key is turned in the ignition.
You might even end up hearing a clicking sound. If your engine does not crank even a little bit, the faulty starter motor may be the reason.
Defective Starter Solenoid
Will your car won’t turn over but has power, but your starter motor is running fine? In certain cases, the reason can be a faulty starter solenoid. This element is located in the starter, but if your car is an older model, it can have this part separately placed. If you are hearing a clicking noise, it can be due to a faulty starter solenoid.
A Bad Transmission Range Selector Contact
You will find the range selector placed inside the automatic transmission shifter. This is also called the neutral safety switch. In cases of bad electrical contact, the engine fails to recognize whether it is located in a park or neutral. If recognized at an early stage, one can actually take control of the problem. What to do now?
Put your foot on the brake. The next step is to move the lever to neutral. Then start the engine. If it does not work, turn the car into Park again and then try again. Try to move the shifter to establish the required electrical contact.
Defective Wiring
In the intricate dance of a car’s engine, a web of wires weaves its way through the mechanical heart, extending from the switch to the starter. For your car to perform at its peak, these wiry veins must be in tip-top shape.
Should the connection between your vehicle’s ignition switch and the starter solenoid—the conductor we spoke of earlier—falter during your drive, your car may come to an abrupt and unexpected halt.
Seized Engine
Your car won’t turn over but has power? A seized engine can be the reason for it. Another hint for this problem is that all the electronics will be working just fine. What causes the engine to seize?
This can be caused due to low engine oil. Another common reason for the same is the water that infiltrates the car system. A worn-out engine or overheating of the car can also lead to this issue.
Faulty ignition
Remarkably akin to the starter engine, a malfunctioning ignition switch can hinder your car from springing to life. How can you discern if a damaged ignition is to blame when your car refuses to turn over, despite having power?
If your headlights shine bright, yet your car remains stubbornly silent, it’s evident that the battery is charged and healthy. This narrows the list of suspects, pointing an accusatory finger at the ignition switch as the likely offender.
My car won’t start but has power due to a damaged, faulty ignition; what can be done about it? Your starter engine can be jumped using a charged battery.
Problem With The Alternator
If your car won’t start but has power, it is time to look into your alternator. What is an alternator? It is part of the car that derives power from the engine and then recharges the battery when the car is running. A standard electrical cycle of a car is extremely important as a problem with it fails the car to start altogether. If the alternator can not charge the battery, the stored energy gets exhausted and thus dies.
If recharging fails, the car’s electrical system fulfills its need for power from the battery. This can cause the battery to die. In order for a car to start, its starter motor will require electricity from the battery. If the latter is dead, the car will fail to start.
Is it the alternator? How can I check it? It is extremely simple to check. Let us see how.
You can easily jumpstart your car. You should then measure the voltage at the battery terminals using a multimeter. If the reading shows to be less than twelve volts, the battery could very well be dead.
Now, rev the engine and notice the reading. You should look for an increase in the voltage reading. In the case of a good alternator, electrons will rush into the battery when the engine begins to run. If you do not notice a chance or even a small increase in the reading, it indicates a poorly working alternator.
Suppose your car won’t turn over but has power due to a faulty alternator. In that case, you should look into its coil, which is responsible for converting the rotational motion from the vehicle’s engine into the required alternating current. A problem like this requires a professional’s attention at the earliest.
A Poor Air Intake System
Some rare reasons can cause problems in your car and prevent it from turning on. Your car won’t turn over but has power? A poor intake system can be the reason for this issue. Your engine needs air to burn the fuel required to run the engine.
Blocked air filter
Will your car won’t start but has power? There is a chance that it is happening because of your car’s blocked air filter. If no other options match, try looking for a choked or clogged filter. A replacement may be in order. Look up the air tube to ensure no debris, animal nests, or webs clogging the way.
Bad MAP or MAF sensor
Will your car won’t turn over but has power? Are you struggling to find the reason why? What does the MAP or MAF sensor have to do with it?
Let us start by understanding these two terms. MAP stands for Manifold Absolute Pressure, while MAF is associated with mass airflow sensors. These two measure the pressure and volume of the air being pumped into the engine.
If there is any problem with the MAP or MAF sensor, the engine will not start and can show wrong readings. Start the engine again after unplugging the sensors. Replacement is your best option.
Car Won’t Start But Has Power: Cranking Voice of the Engine
Does your car crank but refuse to start? If the engine is cranking, it signals that your vehicle’s electrical system is in fine form. To guarantee a smooth journey, three key elements must be present: fuel, a functioning fuel filter, and a spark.
A hiccup in any of these components may result in the exasperating cranking noise that accompanies a stubbornly unresponsive car. Let’s delve deeper into this conundrum.
Fuel
Car won’t turn over but has power? Do you suspect a fuel problem? That is a common cause. There are a few ways that this problem can take place. If you live in a cold area, you are most likely to experience a frozen fuel line. It thus needs to be thawed. An empty gas tank is also a cause for the same, along with a miscalibrated fuel gauge.
Fuel Filter
The car won’t start but has power? Grab your owner’s manual to understand the fuel filter, which is another common reason for the same. Check the information on the fuel filter and double-check the advised date for replacement. Even a clogged one will hinder the gas supply to the engine. A helpful tip is to not run your vehicle all the way to empty.
Dead or No Spark
A common culprit is the lack of spark in the engine. A spark is essential for the ignition of the fuel, which then lets the car start.
What Can Be Done?
My car won’t turn over but has power; what should be done? The first step is to identify the problem. If you are handy with the engine, you can tackle some of the issues yourself. If not, take your car to the local mechanic and ask for a full diagnostic. Regardless of whether your car is currently showing symptoms or not, it is extremely important to get your car checked, i.e., maintenance regularly.
If you have figured out the issue and know that it is the starter that is causing the car to not start, you need to replace it. You are better luck if you have a manual transmission vehicle, as you can push-start the vehicle. If your car won’t start but has power, there can be many reasons behind it; let us look into a few more.
If you feel the starter solenoid is faulty, you can bypass it with a screwdriver. Ensure that the screwdriver in discussion is insulated. Will your car won’t turn over but has power? Take the insulated screwdriver and carefully place the metal blade across the vehicle’s contacts. This should create a bridge-like structure between the starter motor and the ignition switch.
Ensure that the car is raised from the ground, and make sure that the rest of your hand does not come in contact with the rest of the engine.
Will your car won’t turn over but have power due to faulty wiring? This can be really confusing to deal with. You need to systematically go through the many cables inside your engine and follow them to ensure their integrity and their proper connection.
If the answer is a seized engine, then you are stuck with hard luck. The only ways to go about them are to get them rebuilt fully or to get them replaced. This is a costly affair which is why an old or worn-out car may just not be worth it.
Cost
My car won’t start but has power, how much will it cost?
The cost of addressing your car’s issue will span a wide range, depending on the root of the problem. If the starter is the culprit, replacing it will set you back between $400 and $600, with $100 to $150 going toward parts alone.
Should a faulty transmission range selector be the cause, you’ll need to replace it at the cost of approximately $125 to $200, with parts accounting for $75 to $125 of that total. If the problem lies in defective wiring, the solution tends to be more affordable. The trickiest part is identifying the problematic wire.
Once located, you can either reestablish the connection or replace the wire if necessary. However, brace yourself for heftier expenses in the case of a seized engine.
Depending on your car’s model, engine replacement or rebuilding can easily exceed $3,000! To minimize costs, avoid dealerships, as they typically charge more.
Remember that repair costs hinge on factors like your car’s model, part availability, and labor fees. Part costs fluctuate based on market availability and your specific vehicle, while labor fees are influenced by your location.
Can you fix a car that won’t turn over but has power at home? That depends on your engine knowledge and proficiency. The issue at hand and your skill set will determine whether a DIY repair is feasible.
Simple fixes like a clogged air filter or loose wires can often be tackled at home, even by novices. However, a seized engine will require professional intervention. Promptly address any issues with a car that won’t turn over but has power.
Delayed action can lead to more serious engine complications and, consequently, higher expenses.
