Your Toyota Corolla’s inability to start is likely due to a weak or dead battery. Of course, there are other factors that could be at play, but battery issues are the most frequent. Given that your Toyota was operating normally yesterday, the problem is almost certainly a dead battery.

Why won’t my Toyota start?
Typically, all you need to do to solve an issue is jump start a dead battery (ideally using a jump box or portable battery charger) and let the alternator to recharge the battery for around 30 minutes.
When the battery is healthy, what prevents a car from starting?
It might seem simple, but if your battery, spark plug, and alternator are in good shape, you should check to see if your automobile has adequate fuel.
What can you do about it?
Before you start driving, check that your gas tank has enough fuel, and make an effort to keep it filled up.
During the winter, a fuel line in your car could even freeze. Keep in mind that the more space there is for water vapor to condense and freeze inside your car’s gasoline line, the more empty a gas tank or fuel tank there is.
Finally, have your gasoline reading gauge checked if it frequently runs out to the point that your car won’t start. The gauge can be defective and unable to provide you with the appropriate reading at the appropriate moment. Any other underlying problems with the fuel system will also be found by a mechanic.
Why would my car suddenly stop starting?
A fading or dead battery, frayed or corroded connecting cables, a defective alternator, or a problem with the starter are the common culprits when a vehicle won’t start. It can be challenging to tell whether a battery or alternator issue is at hand. Here’s how to determine who the culprit is.
Bad Battery Symptoms
Consider a failing battery, a loose or corroded connection, or an electrical draw if your car cranks slowly, starts inconsistently, is harder to start on chilly mornings, or doesn’t make any sound or light up the interior when you try to start it. A low battery with terminal corrosion that is obvious is likely damaged.
If a jumpstart is successful, a battery issue is present. However, you must also determine whether it is just nearing the end of its life or whether there are more serious problems. A malfunctioning alternator may be the cause of a dead or depleted battery. The additional pull from auxiliary lights, fuses, sound systems, alarms, and other devices may also be the cause.
How come I have electricity but my car won’t start?
When a new engine won’t start, the battery is typically at blame. However, a dead battery and an alternator are mostly out of the question if the car is still getting electricity. Some batteries could ship from the factory with a lesser charge retention capacity. This is a manufacturing flaw, and the warranty allows for a replacement.
However, it is simple to believe that the battery is in perfect condition if a car won’t start but still has power. It can be very deceiving, especially if the lights, horn, and other electrical components work well. This is because not all peripherals use the same amount of energy.
To start the engine, however, the starter motor requires a lot of power. It’s possible that a battery nearing the end of its useful life won’t be able to power the starter motor sufficiently. Additionally, some electronic ignition systems start out by using a lot of energy. But since they draw less power from the battery, accessories like lights, horns, and radio systems might function.
Everyone may become confused at this point. So, get your multimeter and examine the battery terminals if your car won’t start but has electricity. It should ideally read 12 volts with the engine off, if not extremely near to it. The battery is on the verge of dying if not.
Start the car, switch on most of the accessories, and read it once more. When you press the accelerator, the voltage shouldn’t drop; instead, it should rise to 13.5 to 14 volts. If this doesn’t happen, there might be a problem with the alternator. When a car won’t start yet has power, this is the most typical problem.
What could prevent a Toyota Corolla from starting?
Toyota Corollas have been around for a while and have established themselves as trustworthy, dependable vehicles. Even these vehicles occasionally experience challenges, and starting is one among those issues.
If you consider all of the potential causes of the problem, the majority of Toyota Corolla starting issues may be fixed rather quickly and inexpensively. The issue could be with the starter, alternator, key fob battery, weak battery, corrosion on the terminals, or any number of other issues.
Always start with the simplest solution first since the simplest explanation is typically the accurate one. Since the Toyota includes an inbuilt diagnostics system, one item, an OBD2 scanner, can be very useful.
The OBD2 connector, which is found under the dashboard, is where the scanner is connected. Without starting the engine, carefully connect the wires, and switch the ignition to the auxiliary position.
You will need to enter some data, so be prepared with details like the engine type and car identification number.
Why won’t my car start even though the battery is not dead?
Damaged or Broken Ignition If your headlights work but your car won’t start, your battery is charged but the starter or ignition isn’t working properly. A starting engine can be jumped using a charged battery if the starter or ignition is the issue.
How can I determine whether the starter fuse is blown?
Some starter relay fuse failure indicators are obvious, while others are less obvious. There are a number of tools required to adequately test for defects if you think your starter relay may be malfunctioning, including a voltmeter, wires, wrenches, and sockets.
To better understand whether the fuse is operating properly, you can use the multimeter to measure the voltage that is traveling through it. The sockets and wrenches are required to remove any vehicle parts in order to reach the fuse, and the wire serves as a jumper.
Check Voltage
Connect the red probe of your multimeter to the battery’s red terminal and the other to the circuit for the ignition switch when the multimeter is set to 20V DC. Have a helper turn the key and start the engine while they are seated in the driver’s seat.
Be sure to keep an eye on your multimeter while the engine starts. You have an electrical conductivity issue and require a new starter relay fuse if the voltage lowers by more than 0.2 volts.
Check Electrical Resistance
Put the probes of your multimeter on the ignition circuit terminal and ground lead to test the electrical resistance. The starting relay fuse needs to be replaced if the multimeter value is greater than 5 Ohms.
If you don’t have a multimeter, you can measure electrical resistance using a wire. The wire should have one end on the battery lead and the other on the ignition circuit. The starting relay does not need to be replaced if you hear a loud click. However, a weak click is a good indication that the fuse is bad if there is one.
Why do the radio and lights in my car work but my car won’t start?
Your lights turn on, and the radio is functional, but your car won’t start, and there is no sound. This indicates that there is no electricity going to the starter motor. It therefore indicates a difficulty with the starting ignition system. This can be the ignition switch, starter solenoid, or battery.
What does it imply if your car won’t start and your brake pedal is stiff?
The majority of contemporary automobiles include power assist, which depends on a brake vacuum to function. If you’ve been applying pressure to the brakes while the engine is off, you may have exhausted the reserve vacuum in the vehicle. The result will be a hard brake pedal.
What sensors could prevent an automobile from starting?
In addition to the more typical problems like a drained battery or a damaged starter, defective sensors can also make it difficult for modern cars to start. So which vehicle sensors could be the root of this issue? Here is what you need to know after our investigation:
The following sensors are those that frequently prevent a car from starting:
- Sensor for Camshaft Position
- Sensor for Fuel Pressure
- Sensor for Oil Pressure
- sensor for the brake pedal
- Sensor for Throttle Position
- Sensor for Crankshaft Position
- Sensor of Mass Air Flow
- Absolute Manifold Pressure Sensor
Many regular automobile owners are unfamiliar with these components, despite the fact that many seasoned automotive enthusiasts may be. Continue reading, and we’ll try to explain what these sensors are and how to tell if they’re failing.

Why won’t my Toyota Corolla start despite cranking?
Most frequently, a malfunctioning gasoline pump is at blame. It’s possible that the fuel pump fuse has blown, or the fuel pump will need to be replaced. Alternately, a fuel line leak, clogged fuel injectors, or a malfunctioning fuel pressure regulator could be to blame for this issue.
How much does a Toyota Corolla starter replacement cost?
Estimated price for replacing a Toyota Corolla starter. Replacement starters for Toyota Corollas typically cost between $312 and $391. Between $60 and $75 is the projected labor cost, while between $252 and $316 is the estimated cost of the parts.

How can you identify if the issue is with the ignition switch or starter?
Examine the starter. It is located underneath the hood, typically on the passenger side, right close to the transmission at the bottom of the engine. The ignition switch, which often sits on the steering column, is a group of electrical contacts that turns on the starter.
The starter fuse is where, exactly?
By vehicle type and model, the start relay’s location varies. The right fender, the instrument panel under the fuse panel, or the fuse box (also known as the power box) are all potential locations. It will typically be in a sizable box with a black top under the hood of your car. Relays and fuses for automobiles are fitted here. It can also be known as a fuse box. Usually, the driver’s side of the car has this box fitted.
The relay receives and discharges wires. However, a lot of other relays in autos look similar. It could be challenging to locate or even remove the fuse box under the dashboard that contains the starting relay. Finding the starting relay that is fastened to the fender wall might not be difficult. The mounting posts and leads on these relays, which are typically cylindrical, can be used to identify them. Please consult your service handbook if you are unsure which relay serves as the beginning relay.
