Understanding Why a Toyota Won’t Start

First it’s important to have a grasp of the issue. When you hop into your car and realize “My Toyota FJ Cruiser won’t start”, this could be because of an array of things being wrong with your car. Possibly the engine is not firing up at all, possibly it is cranking partially but then not starting, or possibly it’s making a clicking noise when you attempt to start the engine, but ultimately absolutely nothing happens. Each of these scenarios can indicate various issues with your car.

Common Reasons Why Your Toyota FJ Cruiser Won’t Start

There are many reasons a FJ Cruiser will not start. These concerns usually include a dead or weak vehicle battery, a bad alternator, starter motor issues, fuel system problems, as well as electrical or wiring concerns. Every one of these problems can manifest as an array of symptoms and require different solutions to troubleshoot and fix, so we can get your car back on the road as soon as possible.

Symptoms of Toyota FJ Cruiser That Won’t Start

Being able to identify and diagnose these signs, will assist you in discovering the root cause of the problem. For instance, when you turn the key in the ignition, and you hear a clicking noise but your Toyota still won’t start, it is often a sign that there is a problem with the fuel or ignition system of your car.

Analysis of The Reasons Why Your Toyota FJ Cruiser Won’t Start

The initial step to finding a practical solution to the problem is having a grasp of the underlying cause of that problem, so let’s explore the most common reasons your FJ Cruiser fails to start.

Toyota FJ Cruiser Battery Issues

In the majority of cases, the most common reason why your Toyota FJ Cruiser won’t start is, in many cases because of the battery, it’s either weak or dead, and you need to either recharge your car’s battery or replace it. The vehicle’s battery supplies the power required to start the engine, and power all the electrical parts in your Toyota FJ Cruiser. Symptoms of a weak or dead battery issue in a FJ Cruiser, can be things like the car being sluggish to crank the engine, dim headlights, or a lit-up battery caution light on the dash.

Toyota FJ Cruiser Alternator Problems

Alternator problems can stop a Toyota from starting

The alternator is tasked with charging the battery from the engine while the car is running. A broken alternator can easily prevent your Toyota FJ Cruiser from starting as it won’t be able to charge the battery, from the engine, so it will drain all the way down till it’s dead and you don’t realize it until you get into your beloved FJ Cruiser and it refuses to start. Symptoms that your car’s alternator is faulty include a lit-up battery or alternator caution light on the dash, poorly lit headlights when the engine is idling, and also a whining or grinding noise from the engine while it’s running.

Toyota FJ Cruiser Starter Motor Failures

Toyota starter motor problems

When you start your Toyota FJ Cruiser, the starter motor handles turning the engine over (cranking it). If the starter motor is failing in some way then the engine won’t crank, and your FJ Cruiser won’t start. You can tell if your starter motor has an issue or not often by listening, if you hear a clicking noise when you turn your key or a grinding sound throughout the start-up, or your vehicle can start, but only intermittently then the starter motor may very well be the problem.

Toyota FJ Cruiser Fuel System Complications

my car wont start but clicks We’re not talking about when you simply run out of gas here, but your car’s fuel system itself having issues. Your Toyota FJ Cruiser uses a combustion engine, and , therefore, to start and run, it requires a proper mix of fuel and air. If your FJ Cruiser problems are because of a faulty fuel system, this can be a clogged fuel filter or a failing fuel pump relay, which could mean the engine may not be receiving the fuel it requires to get the vehicle going.

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

Toyota FJ Cruiser 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 break. Even in an older model, you can still have fairly normal problems such as blown fuses, spark plug problems, a broken ignition switch, or a damaged sensor, and more. These can be some of the numerous electrical reasons why your Toyota FJ Cruiser can’t start. Symptoms of a circuitry or electrical problem can vary widely but can often include the engine not cranking, or your FJ Cruiser can start but only intermittently or some alert lights show on the dashboard. To correctly identify and fix these kinds of problems, you will need the abilities of a knowledgeable car mechanic locally or online.

A digital multimeter can help test electrical components during troubleshooting.

Solutions & Repair Tips For Your Toyota FJ Cruiser Not Starting

Once you have figured out what the cause of your car troubles are. The next logical step is obviously to try and fix it. Here are some tips for the common problems we’ve covered up until now.

How to Troubleshoot and Fix Battery Issues in a Toyota FJ Cruiser

my car wont start i think its the battery If you think it’s possibl a battery issue is the reason your FJ Cruiser has difficulty starting, then the first thing you must do is check the battery terminals. You want them to be clean, not corroded, and tightly connected. If you find that the terminals are indeed 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:

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, 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 probably run out of life once 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 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 FJ Cruiser, and choose a suitable one, from a seller with great reviews.

If charging your FJ Cruiser’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 Customizable mechanic service.

How to Diagnose Alternator Problems in a Toyota FJ Cruiser

car wont start, jumped and started alternator If you’re thinking that the alternator is the cause of your car starting troubles, you can test it to see for yourself. If you can get the vehicle to start up temporarily (you may need to jump-start the car for that), but when it’s going, let the car run, and while it’s running, disconnect the positive terminal of the battery. It’s likely the result of a problem with the alternator if you find your Toyota FJ Cruiser dies fairly quickly when you disconnect the positive terminal.

You should be aware however that this method can be dangerous, and may harm the delicate electronic parts in your Toyota FJ Cruiser, so it’s always best to consult with a professional car mechanic in your area or online, prior to even thinking about this, and I would generally advise against it. Also, a mobile mechanic can come to you and safely repair it on the spot, so no need for any unnecessary risks.

How to Identify Starter Motor Failures in a Toyota FJ Cruiser

In this case, the solution is to have the starter motor changed for a new one by a professional mechanic.

How to Solve Fuel System Issues in a Toyota FJ Cruiser

You ought to hear a humming noise for a few seconds. It might be there is an issue with the fuel pump if you are not able to hear this sound. If you notice your Toyota is tough to start, it stalls, or it has bad acceleration, it could possibly be a result of a clogged fuel filter. Both of these will likely require a reliable car mechanic in order to properly repair.

How to Fix Electrical or Wiring Problems in a Toyota FJ Cruiser

If your Toyota starts after this, then it was a successful, simple and inexpensive repair! Nevertheless, if the car does not start, even intermittently it might be an issue with the ignition switch itself. It could be a faulty sensor if numerous warning lights are noticeable on the dash. These problems can be really complicated and a reliable car mechanic is most likely needed to identify and have it properly repaired.

Preventive Steps

As my dad always said “Prevention is better than cure”, so here are the best ways to make sure you hopefully avoid any Toyota FJ Cruiser starting troubles again!

Routine Maintenance of Your Toyota FJ Cruiser:

Regular maintenance on car to prevent starting issues Regular upkeep of your Toyota FJ Cruiser is crucial to preventing future problems. This consists of things like routine oil changes, checking your car battery, cleaning up the terminals, changing the fuel filter as suggested/required, and having your vehicle checked by a reliable car mechanic routinely. If you are unsure about routine maintenance tasks needed for your specific vehicle, you can speak with a mechanic in your area or online.

Drive Your Toyota FJ Cruiser Regularly:

drive regular to avoid car starting troubles If you happen to leave your Toyota FJ Cruiser in the driveway for extended periods of time without taking it for a spin now and again, the battery will run out of charge as it’s not being charged up by the engine running regularly. Try your best to drive your vehicle frequently to keep the battery from draining. If you remember you have not driven your car in a while, take it for a spin to make sure there is still charge in the battery. Worth noting: letting the battery totally drain, is also damaging to the long-term life of the battery, try not to do this.

Take Notice Of Warning Signs:

Check Engine Control Light on a Vehicle Dashboard If you observe anything strange like uncommon sounds, a difference in how it drives and the performance, or warning lights are now visible on the dash, do not ignore them. These can be early warnings of an issue and it’s best to be addressed ASAP so that they don’t become much bigger problems down the line. Chat with a car mechanic locally or online about these warning lights and find out if they need to be resolved.

When to Ask a Toyota Mechanic Online

Whenever you have a problem, you can search online forever Googling things like “Toyota stopped running while driving and wont start” or you can just speak to an online mechanic now and get the solution in minutes. If you’re either limited on time, want a professional Toyota mechanic on hand helping and advising you, or you’ve actually attempted to solve it by yourself, but despite your best efforts your Toyota FJ Cruiser fails to start, then chatting with a Toyota mechanic online can be an excellent option.

Frequently Asked Questions (FAQs)

Toyota FJ Cruiser won’t start but lights come on?

If your Toyota FJ Cruiser’s lights turn on but it still won’t start, the issue is likely not related to the battery. It’s highly possible there is a problem with the starter motor. Investigate if you hear any clicking noises when trying to turn the key. If so, the starter motor is trying to engage but failing. Have a mechanic examine the starter motor – it may need to be fixed or swapped out.

Toyota FJ Cruiser won’t start but has power?

When your Toyota FJ Cruiser 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 stop fuel getting to the engine.

When you turn the key and just hear clicking but the engine fails to turn over, the most common cause is a faulty starter motor.

As the starter motor needs physical fixing or swapping out, seek help from a reliable mechanic to get your Toyota FJ Cruiser running again.
