Starting Problems In A Toyota Corolla: Why Doesn’t It Start?

Hi-ya! good afternoon, at this moment we will made an article about Starting Problems In A Toyota Corolla: Why Doesn’t It Start?

When you turn the key on your Toyota, you expect it to start. That’s one of those little things in life that you take for granted. But a vehicle that won’t start can indicate a host of problems. Here we will tell you all about the starting problems in a toyota corolla.

In the event of boot failures, you can try to isolate the problem and identify which part is causing the problem by doing just a few tests.

It’s up to you to determine where the problem is. If the key does not turn in the ignition, your vehicle may have a steering lock. You just have to turn the steering wheel a little bit to unlock it and allow the key to turn.

Not all solutions are that simple, so let’s look at some of the other problems you may have when your Toyota Corolla refuses to start.

Electric problems

When a Toyota Corolla does not want to start, the first thing to do is check that there are no electrical problems.

1- Fuses:

Not all models have a fuse connected to the starting system, but a simple check of the fuses can quickly rule this out.

2- Battery:

If the battery connections corrode, there is no longer a connection to the rest of the Corolla. This may prevent it from booting. You should clean the studs and try to start the car again.

Also, the battery may be dead. Take a battery tester and check the cranking amps to see if they are weak. When the battery is bad it is best to replace it; change it and clean the connections.

3- Power switch:

If the battery works, but you still can’t start your Toyota Corolla, it could be the ignition switch. Turn the key to the ON position and look for the red warning lights on the dashboard. If the lights don’t come on and the battery is working, the fault may lie with the ignition switch.

If the dash lights come on, then turn the key to start to see if the dash lights turn off. If the lights go out, the ignition key is good.

4- Starter motor connection:

The starter motor corrosion can cause the Toyota Corolla not to start. To test the connection, hold the jumper cable with a circuit tester. It will be the smaller of the two cables.

Stay away from moving engine parts and have someone turn the key. Check the starter motor current. If the starter has power but is not turning, then you need to replace the starter. But if the starter works fine, the problem is somewhere else.

You may not be getting any spark at all, so the next thing to check is the ignition system.

5- Coil:

Test the ignition coil with a multimeter and if it’s bad, replace it.

6- Distributor cap:

Remove the cap and check for moisture in the cap. Although it’s probably not the problem, it’s always good to check for cracks or moisture. Dry it and put it back or change it if it is cracked; then see if the vehicle starts. Don’t forget that most newer vehicles don’t have a distributor cap.

7- Spiral cable:

A broken or shorted coiled cable can prevent your Corolla from starting. Look at the cable to make sure it isn’t cracked or split. Use a circuit tester to check for continuity.

fuel problems

If starting problems persist on your Toyota Corolla but you notice it is getting power and the starter motor is turning, then the problem may be with the fuel system.

1- Electrical connections:

The fuel injection system has many electrical connections. They are connected at the top, on the intake air side and on the cylinder heads. If there is a connection you should check that everything is ok.

2- Fuel pump and relay:

The fuel system needs to be pressure tested in case you have the necessary equipment then test it. Use a circuit tester to check all electrical connections to the fuel pump. Turn the key to ON; if you notice that there is current, then it is not the pump. If there is no current, check the fuse. If you have a good fuse then replace the fuel pump relay.

3- Fuel filter:

If you have a working fuel pump, the fuel filter may be clogged. It should be part of your maintenance plan, so if it’s clogged, replace it.

Tips

All of these suggestions are things you can do at home. You can do more extensive tests with the right equipment.

  • starter: Your Corolla’s starter may be loose, so make sure it’s screwed into place.
  • injectors: A faulty injector can prevent the engine from firing.
  • cold start valve: If the engine is cold and the cold start valve is bad, it can cause your Toyota Corolla not to start.
  • flywheel or ring gear: Worn teeth on these gears can prevent the car from starting; they will screech when undocked.
  • ECU o Sensor MAF: Your car’s computer may be broken. If that’s the case, you’ll need to go to your dealer for help.

If you are still experiencing starting problems on your Toyota Corolla, then you may find yourself in a situation that is beyond the scope of the solutions provided here.

In case you have done all the checks you could and it still won’t start, then you may need to check with your local Toyota dealer.
