In the vast majority of instances, the most common reason why your Toyota Avalon won’t start is often the result of your battery, it’s either weak or dead, and you have to either charge up your car’s battery or change it. The vehicle’s battery supplies the power that’s needed to start the engine, and power all the electrical parts in your Toyota Avalon. Signs of a weak or dead battery issue in an Avalon, can be things like the vehicle being sluggish to crank the engine, poorly lit headlights, or a lit-up battery caution light on the dash.

Toyota Avalon Alternator Problems

Alternator problems can stop a Toyota from starting

The alternator is responsible for charging the battery from the engine while the car is running. A broken alternator can certainly prevent your Toyota Avalon from starting as it wont have the ability to charge the battery, from the engine, so it will be depleted fairly quickly until it’s totally dead and you don’t realize it until you can’t get your Toyota to start. Symptoms that the alternator is faulty include a lit-up battery or alternator warning light on the dash, dim headlights when the engine is idling, and also a whining or grinding noise from the engine while it’s running.

Toyota Avalon Starter Motor Failures

Toyota starter motor problems

When you start your Toyota Avalon, the starter motor deals with turning the engine over (cranking it). If the starter motor is broken in some manner then the engine is not going to crank, and your Avalon won’t start. You can tell if your starter motor has a problem or not often by listening for a clicking noise when you turn your key or a grinding noise throughout the start-up, or your car only starts intermittently then the starter motor may very well be the problem.

Toyota Avalon Fuel System Complications

Your Toyota Avalon uses a combustion engine, and because of this to start and run, it needs a combination of both fuel and air. If your Avalon issues are because of a faulty fuel system, this might be a clogged fuel filter or a damaged fuel pump relay, which could indicate the engine might not be receiving the fuel it requires to get the vehicle started.

A fuel injector cleaner can help clean out the fuel system if clogged injectors are suspected.

Even in an older car, you can still have regular problems such as blown fuses, spark plug issues, a faulty ignition switch, or a broken sensor, and more. These can be a few of the many electrical reasons your vehicle won’t get started. Symptoms of a circuitry or electrical problem can differ widely however can often include the engine not cranking, or your Avalon can start but only intermittently or some warning lights come on the car’s dash. To appropriately diagnose and fix these kinds of problems, you will require the skills of an experienced car mechanic locally or online.

Solutions & Repair Tips For Your Toyota Avalon Not Starting

Once you have found out what the cause of your car being unable to start is. The next logical step is obviously to try and fix it. Here are some pointers for the typical issues we’ve covered up until this point.

How to Troubleshoot and Fix Battery Issues in a Toyota Avalon

my car wont start i think its the battery If you think it’s possibl a battery problem is the reason your Avalon has difficulty starting, then the first thing you must do is examine the battery terminals. You want them to be clean, not corroded, and tightly connected. If you discover that the terminals are corroded you can try to clean them up with a mix of baking soda and water.

Once you have checked the battery terminals, you can check to see if the battery is out of charge, or is weak or dead and needs to be replaced. For this, you can charge the battery in a few different ways:

Energizer Jumper Cables for Car Battery, Heavy Duty

If the battery charges up and works fine, great, problem solved! However, if the battery is old or weak, you will have to replace it, otherwise, even if you charge it up enough to start the car, it will likely die once again in the near future. You can make use of a multimeter or OB2 scanner as a way to test the life of the battery to find out if it’s worth saving or if it needs swapped out for a new one. You can get a replacement car battery for your exact Toyota model by visiting Amazon here, and selecting “enter a new vehicle” to filter the results for your Toyota Avalon, and choose a suitable one, from a seller with great reviews.

If charging your Avalon’s battery does not resolve your issues, and problems like frequent draining and needing frequent charges persist even after replacing the battery, there is likely a more complex underlying issue causing excessive battery drain. In that case, you will need a professional mechanic to inspect and diagnose the root cause. You can also ask the advice of a mechanic online through us, or get an instant free quote on a At-home car repair.

How to Diagnose Alternator Problems in a Toyota Avalon

If you can get the vehicle started temporarily (you may need to jump-start the car for that), but when it’s going, let the car run, and while the engine is running, disconnect the positive terminal of your car’s battery. It’s likely because of a problem with your car’s alternator if you notice that your Toyota Avalon dies pretty quickly when you disconnect the positive terminal.

However, be warned this test can be risky and dangerous if you don’t know what you’re doing, and might damage the delicate electronic parts in your Toyota Avalon, so its best to talk to an experienced mechanic locally or online, prior to ever trying this Also, a mobile mechanic can come to you and safely repair it on the spot, so no need for any unnecessary risks.
