Perhaps the engine is not turning over at all, perhaps it is turning over partially but then not starting, or possibly you can hear a clicking noise when you attempt to start the engine, however ultimately absolutely nothing happens. Each of these annoying situations can indicate various issues with your car.

Common Reasons Why Your Toyota Sequoia Won’t Start

There are various reasons a Sequoia refuses to start. These concerns usually include a weak or dead car battery, a bad alternator, starter motor issues, fuel system failures, along with electrical or wiring problems. Every one of these issues can show up as different symptoms and require separate solutions to detect and resolve, so we can get your car back on the road as soon as possible.

Symptoms of Toyota Sequoia That Won’t Start

Having the ability to identify and diagnose these signs, will help you in discovering the underlying cause of the problem. For example, when you turn the key in the ignition, and you hear a clicking noise however your Toyota still can’t start, it is often a sign that there is an issue with the fuel or ignition system.

Analysis of The Reasons Why Your Toyota Sequoia Won’t Start

The first step to finding a solution to the problem is having a grasp of the underlying cause of that problem, so let’s explore the most typical reasons your Sequoia will not start.

Toyota Sequoia Battery Issues

In the majority of instances, the most common reason why your Toyota Sequoia will not start is often because of the battery, it’s either dead or weak, and you have to either recharge the battery or change it. The vehicle’s battery provides the electricity needed to start the engine, and power all the electrical parts in your Toyota Sequoia. Signs of a weak or dead battery issue in a Sequoia, can be things like the vehicle being slow to crank the engine, weak or dim headlights, or a lit-up battery alert light on the dash.

Toyota Sequoia Alternator Problems

Alternator problems can stop a Toyota from starting

The alternator is tasked with charging the battery from the engine while the vehicle is running. A faulty alternator can easily stop your Toyota Sequoia from starting as it will not be able to charge up the battery, from the engine, so it will drain fairly quickly until it’s dead and you don’t realize it until you can’t get your Toyota to fire up. Signs that your Sequoias alternator may be faulty can be a lit-up battery or alternator warning light on the dash, weak or dim headlights when the engine is idling, and also a whining or grinding sound from the engine while it’s running.

Toyota Sequoia Starter Motor Failures

Toyota starter motor problems

When you start your Toyota Sequoia, the starter motor deals with turning the engine over (cranking it). If the starter motor is damaged in some way then the engine is not going to crank, and your Sequoia will not start. You can tell if your starter motor has a problem or not typically by listening, if you hear a clicking noise when you turn your key or a grinding noise throughout the start-up, or your vehicle can start, but only intermittently then the starter motor may very well be the problem.

Toyota Sequoia Fuel System Complications

Your Toyota Sequoia uses a combustion engine, and , therefore, to start and run, it needs a combination of both fuel and air. If your Sequoia problems are because of a faulty fuel system, this might be a clogged fuel filter or a broken fuel pump relay, which could mean the engine may not be receiving the fuel it requires to get the car going.

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

Toyota Sequoia Electrical System or Wiring Problems

Ok, well yes that image is a joke, but in all seriousness, modern Toyotas rely greatly on electronics, which can mean there are lots of things that can potentially have an issue. Even in an older car, you can still have regular problems such as blown fuses, spark plug issues, a damaged ignition switch, or a faulty sensor, and more. These can be some of the many electrical examples of how failing electrical components can be the reason your vehicle won’t start. Symptoms of a wiring or electrical problem can vary widely however can often include the engine not cranking, or your Sequoia can start however only intermittently or numerous alert lights come on the car’s dash. To effectively diagnose and fix these kinds of problems, you will require the abilities of a knowledgeable car mechanic in your area or online.

A digital multimeter can help test electrical components during troubleshooting.

Solutions & Repair Tips For Your Toyota Sequoia Not Starting

Once you have determined what the reason for your car failing to start is. The next step is obviously to try and fix it. Here are some pointers for the typical problems we’ve covered so far.

How to Troubleshoot and Fix Battery Issues in a Toyota Sequoia

my car wont start i think its the battery If you think it’s possibl a battery problem is the reason your Sequoia has trouble starting, then the first thing you ought to do is inspect the battery terminals. You want them to be clean, not corroded, and tightly connected. If you find that the terminals are corroded you can try cleaning them 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:

Robby Recommends:

Portable Car Battery Jump Starter Charger - NOCO Boost Plus GB40

At Home Battery Charger - YONHAN - Fully Automatic

Jumper Cables by Energizer for Car Battery - Heavy Duty

NOCO Boost Plus GB40 1000A UltraSafe Car Battery Jump Starter

YONHAN Battery Charger Fully-Automatic

Energizer Jumper Cables for Car Battery, Heavy Duty

If the battery charges up and works fine, great, problem solved! However, you will need to replace the battery if it’s old or weak, otherwise, even if you charge it up enough to start the car, it will probably die again in the near future. You can use a multimeter or OB2 scanner as a way to test the life of the battery to see if it’s worth saving or if it needs to be replaced. 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 Sequoia, and choose a suitable one, from a seller with great reviews.

If charging your Sequoia’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 Local mobile mechanic near me.

How to Diagnose Alternator Problems in a Toyota Sequoia

If you can get the car to start up temporarily (you may need to jump-start the car for that), but once it’s going, let the car run, and while it’s running, disconnect the positive terminal of the battery. If you discover your Toyota Sequoia is dying immediately, then it’s most likely because of an issue with your car’s alternator.

However, be warned this test can be dangerous if you don’t know what you’re doing, and may damage the delicate electronic components in your vehicle, so its best to chat with a professional mechanic locally or online, before ever attempting this Also, a mobile mechanic can come to you and safely repair it on the spot, so no need for any unnecessary risks.

Frequently Asked Questions (FAQs)

Toyota Sequoia won’t start but lights turn on?

If your Toyota Sequoia’s lights illuminate but it still won’t start, the issue may not be related to the battery. It’s highly possible there is a problem with the engine starter. Investigate if you hear any clicking noises when attempting to crank the key. If so, the starter motor is trying to engage but failing. Get a mechanic check over the starter motor – it may need to be fixed or swapped out.

Toyota Sequoia won’t start but has power?

When your Toyota Sequoia has power (lights, radio etc work) but does not start up, there may be a fuel delivery problem. Issues like a faulty fuel pump relay could prevent fuel getting to the engine.

If not, have a mechanic check the fuel system.
