Understanding Why a Toyota Won’t Start

First it’s important to comprehend the problem. When you hop into your car and realize “My Toyota Isis won’t start”, this could be because of an array of issues being wrong with your vehicle. Possibly the engine is not firing up at all, potentially it is turning over partially but then not starting, or maybe it’s making a clicking sound when you try to start the engine, however ultimately absolutely nothing happens. Each of these situations can be a sign of different problems with your car.

Common Reasons Why Your Toyota Isis Won’t Start

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

Symptoms of Toyota Isis That Won’t Start

Having the ability to recognize and diagnose these signs, will help you in discovering the underlying cause of the issue. For example, when you turn the key in the ignition, and you hear a clicking noise but your car still will not start, it can be an indication that there is an issue with the fuel or ignition system.

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

The initial step to discovering a solution to the problem is figuring out the underlying cause of that issue, so let’s look into the most typical causes as to why your Isis will not start.

Toyota Isis Battery Issues

In the majority of cases, the most common reason why your Toyota Isis can’t start is, in many cases due to a bad battery, it’s either weak or dead, and you have to either charge the battery or replace it. The car’s battery supplies the electricity required to start the engine, and power all the electrical components in your Toyota Isis. Symptoms of a weak or dead battery problem in an Isis, can be things like the vehicle being slow to crank the engine, poorly lit headlights, or a lit-up battery alert light on the dash.

Toyota Isis 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 certainly stop your Toyota Isis from starting as it will not be able to charge the battery, from the engine, so it will deplete fairly quickly until it’s completely drained and you only realize it when you can’t get your Toyota to start. Symptoms that your car’s alternator may be faulty can be a lit-up battery or alternator caution light on the dashboard, weak or dim headlights when the engine is idling, and also a whining or grinding sound from the engine while it’s running.

Toyota Isis Starter Motor Failures

Toyota starter motor problems

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

Toyota Isis Fuel System Complications

my car wont start but clicks We’re not talking about when you just run out of gas here, but the fuel system itself having complications. Your Toyota Isis uses a combustion engine, and , therefore, to start and run, it needs a proper mix of fuel and air. If your Isis issues are because of a faulty fuel system, this might be a clogged fuel filter or a faulty fuel pump relay, which could indicate the engine may not be getting the fuel it requires to get the car started.

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

Toyota Isis Electrical System or Wiring Problems

Ok, well yes that image is a joke, but in all seriousness, modern Toyotas rely heavily on electronic components, which can mean there are lots of things that can potentially break and cause problems. Even in an older model, you can still have typical issues such as blown fuses, spark plug issues, a damaged ignition switch, or a faulty sensor, and more. These can be a few of the many electrical explanations as to why your car won’t start up. Symptoms of a wiring or electrical problem can differ widely but can typically include the engine not cranking, or your Isis can start however only intermittently or various warning lights show on the car’s dash. To correctly identify and repair these kinds of issues, you will require the abilities of an experienced car mechanic locally or online.

A digital multimeter can help test electrical components during troubleshooting.

Solutions & Repair Tips For Your Toyota Isis Not Starting

When you have figured out what the cause of your car failing to start is. The next step is naturally to try and repair it. Here are some tips for the typical problems we’ve covered up until this point.

How to Troubleshoot and Fix Battery Issues in a Toyota Isis

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

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 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 replacing. 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 Isis, and choose a suitable one, from a seller with great reviews.

If charging your Isis’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 driveway mechanic.

How to Diagnose Alternator Problems in a Toyota Isis

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 car run, and while the engine is running, disconnect the positive terminal of your car’s battery. It’s likely due to an issue with your car’s alternator if you notice that your Toyota Isis dies instantly when you disconnect the positive terminal.

You should be aware however that this method can be risky, and might damage the delicate electronic components in your Toyota Isis, so it’s necessary to seek advice from 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 Fix Fuel System Complications in a Toyota Isis

You should hear a humming sound for a few seconds. If you are unable to hear this noise, then it may be there is an issue with the fuel pump. If you observe your Toyota is hard to start, it stalls, or it has weak acceleration, it could be a result of 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 Isis

If your Isis starts after this, then it was an effective, low-cost and easy fix! If the car doesn’t start, even intermittently, it could be indicative of with the ignition switch itself. If different warning lights are visible on your dashboard, it might be a faulty sensor. These problems can be extremely complicated and a reliable car mechanic is likely required to identify and fix it.

Try your best to drive your vehicle frequently to keep the battery from draining. Take it for a fast 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 totally drain, is also damaging to the longevity of the battery, try not to do this.

Pay Attention to Warning Signs:

Check Engine Control Light on a Vehicle Dashboard If you observe anything out of the ordinary like unusual noises, a difference in how it drives and the performance, or alert lights showing on the dash, don’t disregard them.
