Toyota Corolla Won’t Start (Do This to Start)

Your Toyota Corolla failing to start just as you’re heading out can completely ruin your day. Finding the root cause is crucial to fixing your car and getting on with your daily activities.

A Toyota Corolla may not start if the battery is dead. This is often indicated by a slow cranking engine or no response when the ignition key is turned. The solution is to jump-start the car or replace the battery if it’s beyond its service life.

Another reason for a Toyota Corolla not starting could be a faulty starter motor. If you hear a clicking sound when turning the key, but the engine doesn’t turn over, the starter motor may need to be replaced.

Lastly, a Corolla might fail to start if there’s an issue with the fuel system. A clogged fuel filter, a failed fuel pump, or problems with the fuel injectors can prevent the engine from receiving the necessary fuel to start. Diagnosing the fuel system, and repairing or replacing the faulty components, will typically resolve this issue.

The rest of the article will share with you the possible starting problems of your Toyota Corolla, their causes, and how to fix them.

Toyota Corolla Cranks but Won’t Start

You’re ready to go out, put your key in the ignition, and you hear the starter engage, but the car cranks a few times until it disengages the starter. There are a few possible causes you might want to check out and their solutions.

  • You’re out of fuel. Check your car’s fuel gauge, and if you identify this to be the cause, you might want to top up your fuel and try again.
  • Fuel pump malfunction. The fuel injector isn’t pumping enough fuel to the engine’s combustion chamber or is not injecting fuel at the right time. The fuel pump system parts that might be responsible include the fuel pump, injectors, filter, and lines.
  • Spark issues. Spark issues might also extend to other parts of the spark system, such as the plug gap, the distributor or module, and spark plug wires.

Toyota Corolla Won’t Start After Fueling

If your car refuses to start right after fueling, it might be due to purge valve leaks. Under normal conditions, when fueling your car, lots of fumes might form in the tank. These fumes typically go into the carbon canister till you put your car on a cruise. If the purge valve leaks, these fumes might fill the engine and intake, causing difficulty starting.

You might want to check and replace the purge valve if you identify it as the cause.

Toyota Corolla Won’t Start After Battery Change

So, you’ve changed your car battery, and your Toyota Corolla has refused to start. If you’re sure that the new battery you’ve installed is in good condition, you might want to start by checking the connection. Confirm that you’ve connected the battery correctly before looking for other possible causes. If the problem persists, here are some other possible reasons to check:

  • Faulty alternator. The alternator is responsible for generating the electrical power and contributes to the charging system.
  • Faulty ignition switches and fuses. A defective ignition switch or a blown fuse might result in a hard start from your Toyota Corolla.
  • Damaged starter relay. The starter or ignition relay might also get damaged from a power surge from the new battery. You might need to take your car to the mechanic to diagnose and fix the ignition switch.

Toyota Corolla Security Light Flashing Car Won’t Start

If your Toyota Corolla refuses to start, but the security or alarm lights are flashing, it might have to do with your alarm system malfunction. It could be because your alarm system doesn’t recognize you as the owner.

Consider disabling or resetting your car’s alarm system to fix the issue. The flashing lights might be due to the immobilizer. Your key fob could also be responsible, and you might fix it with a battery change or repair.

Toyota Corolla Won’t Start, but Battery Is Good

If your Toyota Corolla refuses to start, one of the first points of action is checking on the battery. Try using a battery tester to confirm that your battery is in good condition.

After verifying your battery’s condition, check to see that all battery connections are intact, which could be the cause. The starter, spark plugs, and ignition switches might also be responsible.

Toyota Corolla Won’t Start Clicking Sound / No Click

So, you put your key in the ignition, turn it on, and your car responds with repeated clicking sounds but still doesn’t start. In that case, this might give something to do with your battery. Use a battery tester to confirm that you still have a charge in your batteries and recharge it if it’s low. Corrosion of the battery terminals could interrupt the current flow, and you might want to clean up build-up.

If the batteries don’t seem to be the cause, another likely culprit is the alternator. The alternator is a crucial part of the electrical system and helps charge the batteries. Consider jump starting the car and taking it to your mechanic if you’re still having trouble fixing the problem.

Single clicks might be due to faulty high current contacts within the starter solenoid. You could try replacing the contacts, but replacing the starter assembly might be more manageable since they’re hard to find.

No clicking sounds might mean the problem could be from the fuse box. Consider checking for blown fuses or wiring.

Toyota Corolla Won’t Start When Hot

Check to ensure that you don’t have a fuel problem first before considering other causes. You might also want to eliminate the possibility of a spark plug being the cause.

The usual culprit is the coil or worn distributor bushing. You could take the distributor apart to replace the coil or change the distributor.

Toyota Corolla Won’t Start Oil Light On

The oil light typically indicates that your car is low on oil or a faulty oil pump. Running your car low on oil could damage the engine, so you want to make sure that your car’s oil level is okay and the pump is in good condition.

The oil pump typically connects to the crank, so if your car doesn’t run, there’s no pressure. Consider checking your Toyota Corolla battery and alternator as they could be why your car isn’t starting.

Toyota Corolla Won’t Start Sometimes
