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 may 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.
- Poor injectors can prevent the engine from starting.
- Valve for Cold Start
- Your automobile may not start if the cold start valve is damaged and the engine is cold.
- Starter
- Make sure your starter is bolted down because it can be loose.
- Ring gear or a flywheel
- Your car may not start if these gears have worn teeth. When they are involved, they will shriek.
- A MAF or ECU
- The computer in your automobile can be broken. You must contact your dealership for help if that is the situation.
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.
When your car has power but won’t start, what does it mean?
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.
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.
When your car won’t start but the battery is still functional, what does it mean?
The car may not start even when it clicks when attempting to start due to a weak battery, filthy battery terminals, a damaged starter motor, or a blocked solenoid. There are a few things to try before using jumper cables or an electric jump starter even though it could just need a jump start.
Try Cycling the Key
Turn on the dome light and keep an eye on it while attempting to start the engine if your car would not start after turning on. If the light goes out, the battery is seriously depleted or close to death. Try the key cycling approach to warm up the starter, battery, and connections. The secret is to continually turn the key to the start position—about 10 times straight. Wait five minutes and then stop. then attempt to start the car. However, if the dome light was still on when you turned the key and your car still wouldn’t start, try the next trick.
Try Tapping on the Battery Terminals
When you’re stranded without tools, there is no way to clean corroded battery contacts. However, you can attempt to shake or at least rattle the terminals slightly to improve contact. If the car won’t start, tap each battery terminal with the heel of a shoe to rotate it a little bit around the battery post. Afterward, try starting the car.
Try Tapping the Starter
Try hammering the starter motor with the tire iron from your car jack if you have access to it. The electrical contacts can occasionally become trapped and be released by tapping on them.
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.
What might discharge a car battery?
Extreme weather conditions, electrical equipment or lights left on, a broken charging system or alternator, and other frequent causes can all contribute to a dead battery.
A car battery could discharge for a variety of reasons. But the most typical issues are:
- Parasitic Drain: If your car’s lights or other electrical equipment is left on while the ignition is off, they will slowly but significantly drain your battery’s power. Parasitic drain is a common, eerie description of this.
- Defective charging system: If the alternator, a component of your charging system, is unable to provide enough voltage, ideally between 13.5 and 14.5 volts, your car battery will fast discharge. In this scenario, the battery would keep losing power even when the car is moving.
- Alternately, the alternator could have faulty diodes, which would shorten the lifespan of your battery.
- Extreme weather can harm your automobile battery if it’s too hot (above 100 degrees celsius) or too cold (below 10 degrees Fahrenheit). Long-term storage of your car in either situation would result in sulfate buildup, which would shorten battery life.
- Old battery – A car battery typically lasts 4-5 years, therefore it’s possible that yours is too old to retain a full charge.
Check the electrolyte level, which should ideally be between the LOWER and UPPER marks, if your car’s battery is marked LOWER and UPPER on the side. Other typical indications of a failing automobile battery include:
- Within 15 to 30 minutes of idle with the engine off and other equipment functioning, the battery dies
- When you turn the key to start the ignition, the gauges and lights do not turn on.
- Performing battery jumps every three to five days or perhaps more frequently
- For ignition, use three or more revolutions.
- Before starting, dim any lights and/or accessories.
- increased difficulty starting up after lengthy periods of idling, especially in the cold
Can’t start, but lights are functional?
If the lights and radio in your car are working, the battery is supplying at least some electricity. The headlights consume a lot less energy than the starter motor.
If the battery is not the problem and the engine won’t start, either the starter solenoid, starter motor, or ignition switch is most likely to be at issue.
For the majority of electrical repairs, have your automobile serviced by a reliable neighborhood mechanic or auto electrician. In light of this, don’t be reluctant to conduct your own research. Your suggestions are always valued by the technician.
In conclusion, try not to worry too much. You might need to have your car towed or call a call-out mechanic if you are unable to jump start it. The problem is probably not going to be too pricey or serious, though. Within a few hours, at most, you ought should be able to resume your travels.
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.
