The Correct Method for Giving a Car a Jump Start

Before you get started, you need to check that you have all of the necessary tools and supplies.

If you don’t plan on using a jump-start service like AAA, then you’ll need to make sure that you have a set of jumper cables on hand.

Then you can proceed with the stages as follows:

  • Place the vehicle with the healthy battery so that it is facing the one that needs to be switched off, then park it so that it is facing the other vehicle. Make sure that both of the parking brakes are on before you set out.
  • Locate the batteries and make sure both hoods are open. In order to gain access to the battery terminals, you might have to first remove a plastic cover.
  • Determine which terminals are positive and which are negative. Ensure that they are spotless and free of any corrosion before using them.
  • Establish a connection between the positive post of the dead battery and the red clamp.
  • After unwinding the cable from the battery, connect the other red clamp to the positive terminal of the charged battery.
  • Establish a connection between the negative post of the good battery and the black clamp.
  • Connect the last clamp so that it is secured to an unpainted metal surface on the frame of your vehicle.
  • After ensuring that everything is properly attached, start the engine of the vehicle that has a healthy battery first, followed by the engine of the vehicle that has a dead battery.
  • After the dead vehicle has been successfully jump-started, remove the jumper cables with care, making sure to do so in the opposite order that they were attached, and then turn off the engine of the vehicle that was used to assist in jump-starting the dead vehicle.
  • If you want to make sure that the weak battery doesn’t die again as soon as the vehicle has been restarted, make sure to keep the engine running for at least ten minutes. For more information on the recommended times, please refer to the owner’s manual of your vehicle.

Problems And Solution For A Toyota GT86 That Won’t Start

The most common causes that prevent your 86 from starting normally are a dead battery in the key fob, a dead battery in the 12v battery, corrosion on the battery terminals, a faulty alternator, a clogged fuel filter, a broken starter, a blown fuse, an immobilizer error, an empty gas tank, and any fault in the electrical system.

1. Weak Battery

If the engine in your 86 won’t turn over or turns over very slowly, the problem is very always caused by a weak or dead 12v battery.

If further investigation and a voltage test on the battery are carried out, it will become clear whether or not the starting problem is caused by the battery.

A test can be carried out to determine the state of the starter battery, check the level of acid in the battery, and measure the voltage that exists between the two poles.

If a brand-new battery has recently been put in a vehicle, there is a chance that the battery has not yet achieved its maximum capacity.

A brand-new battery won’t reach its maximum capacity until it has been used for some time.

Test 12v battery

Using a multimeter, you’ll be able to get an accurate reading of the voltage coming from the battery in your Toyota 86.

The voltage range of the battery is selected on the multimeter before the test, and the positive and negative poles of the battery are connected to the multimeter.

The results of a successful test of the automobile battery, also known as checking the voltage, are typical values in the range of approximately 12 to 13 volts.

If the reading is higher than 14 volts or lower than 11.5 volts, you need to have the battery condition professionally evaluated.

Because it is possible that the battery has a flaw given these measured numbers, and it will need to be changed.

You can easily jump-start your 86 if the dead battery is the cause of the breakdown.

Before connecting the red cable to the positive terminal of the donor battery, you must first connect it to the positive terminal of the dead battery in your 86.

Next, connect the black wire to the negative terminal of the donor battery, and then attach the other end of the black cable to the bare metal in the engine compartment of your 86. The donor car should be started first, followed by your 86.

Take the cables out of the wall in the opposite sequence.

2. The battery has developed corrosion

Corrosion on the contacts of your vehicle’s battery will cause a loss of contact as well as a reduction in the flow of current, both of which will prevent your engine from starting in the appropriate manner.

Corrosion on the contacts of the battery can be prevented by regularly cleaning and maintaining the battery.

You need to look into the battery contacts of your 86 in order to determine whether or not the starting troubles are caused by filthy contacts.

If you pull up the two rubber covers that are covering the battery terminals, you will be able to inspect the terminals for any signs of corrosion.

If you see white deposits or deposits that have a silvery-green color to them, but there are no other cracks or damage, you do not need to replace the battery; you just need to clean it.

Remove rust from the battery.

When you want to clean the batteries in your Toyota 86, you have to first remove the pole cables, which does not require any particular expertise but does require some concentration because the order in which you do things is quite crucial.

Before you do anything else, disconnect the black line from the negative pole.

Pliers can be used to release the clamp on the pole even if it is quite secure.

If you choose to use metal pliers despite our advice to the contrary, you are responsible for ensuring that you do not touch any other areas of the body while using them.

After that, you can unplug the red cable that is connected to the positive pole.

Once the corroded battery has been disconnected from the circuit, you can begin cleaning the terminals on the battery.

After you’ve cleaned them, you should reconnect the terminals.

3. An underpowered battery in the key fob

There is a possibility that your 86, which has a push start/stop button, would not start because the battery in the key fob is dead.

You need not worry; even if the battery dies, you will still be able to start your vehicle because it is simply utilized to deliver the signal for locking and unlocking the door.

If the battery in the key fob is depleted, the door will not lock or unlock automatically when the button is pressed.

After that, one will need to manually open the doors. An inactive transponder serves as the controller for the immobilizer.

The fact that the transponder in the key does not require its own independent power supply is one of the meanings of the word “passive.”

How to start a Toyota 86 when the battery in the key fob is dead

If you have a model of the 86 that only has a key fob with a start/stop button and no place to insert a key, then you should try placing your key fob as close to the start/stop button as you can get it and then start the vehicle.

If this doesn’t work, try moving your key fob closer to the button until it does.

If it doesn’t work, look in the owner’s handbook of your vehicle for the specific location of where the key fob is supposed to be placed.

This may be different depending on the model.

A helpful hint is that if you try to start your 86 with the second key, you can exclude the possibility that the first key is malfunctioning due to some other issue, such as water damage.

4. Broken starter motor

A motor known as a starter is used to turn over the engine of your 86 when it has been turned off.

If the engine is started more frequently, the starter motor will only have a life expectancy of roughly 100,000 to 150,000 miles on average, and this life expectancy will be lowered. In any event, due to the fact that the starter motor also has a finite lifespan, it is inevitable that it will fail after an extended period of time spent driving the vehicle.

When you turn the key in your 86 to start the engine, you will hear a clicking sound.

This is the sound of a faulty starter motor. Also, if the starter motor does not work despite having a good battery, you should suspect that there is a problem with the starter.

When the starter fails to function properly, it is typically necessary to replace it with a whole new unit.

Alternate solution for the starter

If the starter is the problem and the engine won’t start, you can try turning the key while hitting the starter motor with anything like a stick or a metal tool to see if it helps.

If the starter is the problem, the engine won’t start.

This workaround is helpful in situations in which the components that make up the starter are jammed together or in which the gears are slightly misaligned.

However, it is possible that the starter is nearing the end of its life, and as a result, it is recommended that you get it inspected at a dealer or repair shop in order to exclude this possibility.

5. Alternator with a malfunction

Alternator with a malfunction

A generator is a device that creates electric current; an alternator is a type of generator. In the event that the alternator in your 86 breaks out, the vehicle will be unable to generate electricity, and the battery will not be able to charge.

Therefore, even if you believe that a dead battery is the cause of the engine not starting and you replace the battery, the battery will soon die and the engine will not start.

This is the case even if you think that a dead battery is the cause of the engine not starting.

Alternators are incredibly reliable and rarely fail. Modern automobiles, in particular, have increased performance, which is why it is said that modern automobiles will endure between 200,000 and 300,000 miles.

In spite of this, it is possible for it to become damaged depending on how you use it, and if you buy a secondhand car, the alternator may already be pretty old.

Maintain a high level of vigilance.

In the event that the alternator fails to function properly, it will need to be replaced with a brand-new alternator.

6. Clogged fuel filter

Your 86’s fuel filter does not wear out as a mechanical part would, but it does become clogged over time as a result of dirt and other airborne particles getting caught in it.

When this happens, the permeability of the filter decreases, and the fuel pressure also falls.

The degree to which this makes a difference is debatable; nonetheless, if the gasoline filter is excessively clogged with debris, the engine will no longer operate at its maximum capacity, and in rare cases it may not even start at all. It is not possible to clean the filter; all that can be done is replace it.

7. Fuel pump failure

If the gasoline pump in your 86 has a problem, the engine won’t be able to start.

In a normal situation, the pump is responsible for ensuring that the required quantity of fuel is transferred from the tank to the injection system of the engine at the appropriate pressure.

In most cases, warning signs will appear well in advance of your fuel pump’s complete failure to function.

For example, if your vehicle’s engine stalls intermittently, starting the vehicle is difficult, the engine jerks slightly, or the engine’s performance decreases, you should have your fuel pump inspected.

It’s possible that this is due to the pump becoming worn out or contaminated.

The gasoline pump is typically noticeable before it completely fails in the event that it is leaking, that a power contact is broken, or that a line or a pump lever is broken.

The faulty fuel pump can be replaced in your workshop if you choose to do so.

8. A burned-out fuse

Your 86 may have broken down due to a blown fuse in some unusual instances.

However, this scenario is extremely unlikely. In order to start the engine, you need to make sure that all of the fuses in the fuse box are in working order.

But exercise extreme caution if you decide to give the fuse box a hand yourself!

Because the box is powered on, any testing or repairs that need to be done must always take place in a workshop.

9. Spark plugs that aren’t working properly

The spark plugs themselves are rarely impacted when there is a problem with the vehicle. Instead, the ignition system’s plug connections become unfastened and loose.

If only one of the plugs is genuinely coming loose, you should be able to solve the problem on your own right there.

A spark plug that has malfunctioned needs to be replaced in the workshop as soon as possible.

10. Rodent damage

Damage caused by rodents is yet another possibility for why your Toyota 86 won’t start.

The animals will get underneath the car and chew their way through the wires and cables.

In theory, this may damage any and all of the vehicle’s systems, including the supply of fuel, the supply of lubricant, or the provision of power.

In most cases, the damage caused by rodents is immediately apparent when inspecting the engine area. In the workshop, we have the means to repair the damage that was caused by the rodent’s bite.

Be ready to pay relatively high prices in this location.

11. Problems with the engine

Even though it happens very infrequently, it’s possible that it was the reason your 86 broke down.

If a car’s engine stops working, then nothing else on the vehicle will either.

It is not unheard of for the operator of a motor vehicle to be held liable for damages of this nature.

The most common causes include a ripped timing belt, improper fueling, an inadequate amount of oil, hydrolock, an overheated engine, and continuous running in an excessive speed range.

In a repair shop, the diagnosis of engine failure requires the expertise of a seasoned mechanic.

Use OBD2 scanner for diagnosis

Because the Toyota 86 is outfitted with on-board diagnostics (OBD), a fault diagnosis can provide preliminary indications as to the location of the issue.

Connecting the diagnostic tool to your 86 is the first step in beginning the troubleshooting process.

The OBDII connector is often found beneath the dashboard in most vehicles.

Turning on the ignition is the next step once the wire has been attached.

However, you must take care not to start the engine.

After then, the majority of diagnostic equipment will inquire about various aspects of the car.

It is essential that you enter this information correctly one hundred percent of the time; otherwise, the outcome of the search could be manipulated.

In most cases, you will also need to fill in the engine and vehicle identification number in addition to the brand and model of the car.

Always double-check the facts to ensure that you are getting the most accurate diagnosis possible.

Toyota Vehicles

  • Toyota Corolla
  • Toyota Highlander
  • Toyota Land Cruiser


There is a wide variety of potential causes if your 86 will not start. When looking for the reason for the problem, you should always begin with the one that is the most evident, which is a dead battery.

In any event, it is recommended that non-technical people call a breakdown service or a workshop for assistance. In the case that there is a flaw, the latter can start the repair process on their own.

A Few Pointers on Jump-Starting a Battery
Under no circumstances should the black cable ever be connected to the negative (−) connection of the dead battery. Because of the potential for an explosion, this activity should be avoided at all costs.

How should the jumper cables be attached, and in what sequence should they go?

The red jumper cables should be attached first. Begin by securing one red cable with a clamp to the positive terminal of the battery that won’t turn over. After that, connect the second red clamp to the positive terminal of the battery that is still functioning. Following this, clip one black cable to the negative terminal of the battery that is working.
