First it’s important to have an understanding of the issue. When you realize to yourself “My Toyota Harrier won’t start”, this could be due to various things being wrong with your car. Maybe it’s a case where the engine is not turning over at all, perhaps it is turning over partially but then not starting, or possibly it’s making a clicking noise when you try to start the engine, however in the end absolutely nothing happens. Each of these situations can be indicative of different issues with your car.

Common Reasons Why Your Toyota Harrier Won’t Start

There are various reasons a Harrier won’t start up. These concerns usually consist of a weak or dead car battery, a broken alternator, starter motor problems, fuel system problems, as well as electrical or circuitry complications. Each one of these issues can show up as various symptoms and require different solutions to identify and repair, so we can get your car back on the road as soon as possible.

Symptoms of Toyota Harrier That Won’t Start

Having the ability to identify and diagnose these signs, will assist you in discovering the root cause of the issue. For example, when you turn the key in the ignition, and you hear a clicking sound however your vehicle still refuses to start, it can mean that there is a problem with the fuel or ignition system.

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

The very first step to finding a solution to the problem is understanding the underlying cause of that issue, so let’s look into the most typical reasons your Harrier fails to start.

Toyota Harrier Battery Issues

In the majority of instances, the most common reason why your Toyota Harrier won’t start is often down to a bad battery, it’s either weak or dead, and you need to recharge your car’s battery or replace it. The car’s battery stores the power required to start the engine, and power all the electrical parts in your Toyota Harrier. Symptoms of a weak or dead battery problem in a Harrier, are things like the vehicle being slow to crank the engine, dim headlights, or a lit-up battery caution light on the dashboard.

Toyota Harrier Alternator Problems

Alternator problems can stop a Toyota from starting

The alternator is for charging the battery from the engine while the vehicle is running. A broken alternator can certainly stop your Toyota Harrier from starting as it won’t have the ability to charge up the battery, from the engine, so it will be drained fairly quickly till it’s completely drained and you only realize it when you get in your Harrier and it won’t start. Signs that your car’s alternator is faulty include a lit-up battery or alternator caution 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 Harrier Starter Motor Failures

Toyota starter motor problems

The starter motor is responsible for turning the engine over (cranking) when you start your Toyota. If the starter motor is defective in some way then the engine may not crank, and your Harrier will not start. You can find out 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 startup, or your vehicle starts up but only intermittently, then the starter motor may very well be the problem.

Toyota Harrier Fuel System Complications

my car wont start but clicks Now we’re not talking about when you merely run out of gas here, but your car’s fuel system itself having issues. Your Toyota Harrier uses a combustion engine, and for that reason to start and run, it needs a combination of both fuel and air. If your Harrier issues are due to a faulty fuel system, this can be a clogged fuel filter or a broken fuel pump relay, which could mean the engine might not be getting the fuel it needs to get the car started.

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

Toyota Harrier Electrical System or Wiring Problems

Ok, well yes that image is a joke, but in all seriousness, modern Toyotas rely greatly on electronic components, which can mean there are lots of things that can potentially break and cause problems. Even in an older vehicle, you can still have fairly normal issues such as blown fuses, spark plug issues, a faulty ignition switch, or a broken sensor, and more. These can be a few of the numerous electrical explanations as to why your vehicle won’t start up. Indications of a wiring or electrical issue can vary greatly but can often include the engine not cranking, or your Harrier can start however only intermittently or some alert lights show on the car’s dash. To effectively identify and repair these kinds of issues, you will need the abilities of an experienced car mechanic in your area or online.

A digital multimeter can help test electrical components during troubleshooting.

Solutions & Repair Tips For Your Toyota Harrier Not Starting

Once you have determined what the reason for your car troubles are. The next step is of course to try and fix it. Here are some tips for the typical problems we’ve covered so far.

How to Troubleshoot and Fix Battery Issues in a Toyota Harrier

my car wont start i think its the battery If you suspect it’s possibl a battery problem is the culprit as to why your Harrier has trouble starting, then the first thing you need to do is check the battery terminals. You want them to be clean, not corroded, and firmly connected. If you happen to 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:

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 vehicle, it will probably deplete quickly once again in the not so distant future. You can use 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 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 Harrier, and choose a suitable one, from a seller with great reviews.

If charging your Harrier’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 Nearby house call mechanic.

How to Diagnose Alternator Problems in a Toyota Harrier

If you can get the car started temporarily (you may need to jump-start the car for that), but when it’s going, let the vehicle run, and while the engine is running, disconnect the positive terminal of the battery. If you discover your Toyota Harrier is dying immediately, then it’s likely because of a problem with the alternator.

You should be aware however that this method can be risky, and might damage the delicate electronic parts in your Toyota Harrier, so it’s necessary to consult with an experienced 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 Harrier

How to Deal With Fuel System Issues in a Toyota Harrier

You should be able to hear a humming noise for a couple of seconds. It may be there is a problem with the fuel pump if you are unable to hear this noise. If you notice your Toyota is difficult to start, it stalls, or it has weak acceleration, it could possibly be due to a clogged fuel filter. Both of these will likely need a professional car mechanic in order to properly repair.

How to Repair Electrical or Wiring Issues in a Toyota Harrier

If your Toyota starts after this, then it was a successful, simple and inexpensive repair! If the vehicle doesn’t start, even intermittently, it could be a problem with the ignition switch itself. It may be a faulty sensor if various warning lights are lit up on the dash. These problems can be extremely intricate and a reliable car mechanic is most likely required to diagnose and repair it.

Preventive Steps

As my father always said “Prevention is better than cure”, so here are some preventative measures to make sure you prevent any Toyota Harrier starting difficulties again!

Regular Maintenance of Your Toyota Harrier:

Try your best to drive your Harrier frequently to keep the battery from draining. Take it for a quick spin to make sure there is still charge in the battery if you remember you haven’t driven your Toyota for a while. Worth noting: letting the battery completely 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 weird like unusual noises, changes in driving and performance, or alert lights showing on your Toyota Harriers dashboard, do not disregard them and get on with your day. These can be early warnings of an issue and are best being resolved ASAP so that they don’t end up being larger issues later.
