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.

What would prevent a Toyota from starting?
If the starting is spinning and you are getting power, the fuel system may be the source of the issue.
Power Connections
There are numerous electrical connections in your fuel injection system. They are joined at the top, on the cylinder heads, and on the intake airside. Check it whether there is a connection.
Pump and Relay for Fuel
If you have the necessary equipment, test your fuel system under pressure. Check all the electrical connections to the fuel pump with a circuit tester. On by turning the key. If there is a current, the pump is not the problem. Verify the fuse if there is no current. Replace the gasoline pump relay if the fuse is functioning properly. (This article has further information about replacing the fuel pump.)
Engine Filter
The fuel filter could be clogged even if the fuel pump is functioning. Replacing it if it’s clogged should be a part of your maintenance schedule. (This article has further information on gasoline filters.)
You can carry out each of these recommendations in your driveway at home. With the right tools, you can conduct more thorough tests.
- A MAF or ECU The computer in your automobile can be broken. You must contact your dealership for help if that is the situation.
- Valve for Cold Start
- Your automobile may not start if the cold start valve is damaged and the engine is cold.
- Ring gear or a flywheel
- Your car may not start if these gears have worn teeth. When they are involved, they will shriek.
- Starter
- Make sure your starter is bolted down because it can be loose.
- Poor injectors can prevent the engine from starting.
While any one of these elements is typically the cause of a car not starting, you can encounter a circumstance where it is outside the purview of these problems. If you have performed all the necessary inspections and the vehicle still won’t start, you might need to speak with your nearby Toyota dealership.
How come my auto decided to suddenly not start?
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.
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.
I have power, so why won’t my car 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.
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.
How can you figure out why a car won’t start?
Why Won’t My Car Start? Diagnosis
- 1) Does the engine turn over?
- 2) Examine the RAM for error codes.
- Crankshaft/camshaft sensors should be examined.
- Four) Verify the fuel pressure.
- 5) Inspect the ignition coil’s spark.
- 6) Verify that the injectors are activating.
- 7) Verify the timing of the crankshaft and camshaft.
- 8) Verify the compression and leakdown test.
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.
Could a blown fuse prevent my car from starting?
Your automobile may act as though it has a defective starter solenoid due to a variety of issues, such as:
Blown fuseOccasionally the most straightforward explanation is the best one. A no-start issue could be caused by a blown fuse in the starter circuit.
corroded or damaged wiring
A starter may not receive enough power if the battery or starter solenoid are connected via damaged, filthy, or loose cables.
All of your car’s electrical systems will be powered by the alternator when it is in motion. The battery is also recharged by it. The battery might not be able to start the engine if the alternator is malfunctioning.
StarterStartenoids vary in location; some are mounted on the starter, while others are housed inside the starter housing. When the solenoid malfunctions in this situation, it could be essential to replace the starting entirely. Sometimes the issue is with the starter itself.
Electrical problems can be inconvenient and irksome. They may also pose a risk and result in harm. Make sure to have a dependable specialist diagnose the precise issue if your car, truck, or SUV displays signs of a faulty starter relay or solenoid.
How can you identify if the problem is with your starter or battery?
Let’s start by diagnosing this problem since it is the least expensive and easiest to replace. Does the car make a clicking noise when you try to start it, but it won’t turn over? That might be encouraging. A dead battery is likely the culprit if a jump starts the car but it won’t start once it is turned off.
Why did my car battery die?
Consider checking to see if you may have left the vehicle’s interior or exterior lights on or if a door may not have closed all the way. We’re confident you already did this as soon as the problem began. Open the hood and inspect the battery terminals if the problem wasn’t caused by the lights. You may only need to give the terminals a brief clean with a toothbrush and some baking soda solution if you notice corrosion (a white powder-like substance) there. Still not an issue? Think about the battery’s age. The average automobile battery lasts 4-5 years. Have your problem diagnosed as soon as possible if your battery is less than four years old and has no other problems. If the problem is with the battery, you might be covered by a warranty and be able to get a replacement. If the diagnosis reveals that your battery is in good condition, the problem may be with the alternator.
The next step is to inspect the alternator if there doesn’t appear to be anything wrong with your battery yet it won’t maintain a charge.
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.
Something sounds off.
When you turn the key or press the start button, there may be a clicking sound, which is one of the signs of a defective starter. However, a starting can stop working altogether or make noises that signal its approaching demise, such as buzzing and grinding. Oh, listen!
