Toyota Land Cruiser Battery Issues

In most cases, the most common reason why your Toyota Land Cruiser will not start is, in many cases down to a bad battery, it's either dead or weak, and you have to recharge the battery or replace it. The vehicle's battery supplies the electric that’s needed to start the engine, and power all the electrical components in your Toyota Land Cruiser. Signs of a bad battery problem in a Land Cruiser, are things like the vehicle being sluggish to crank the engine, dim or weak headlights, or a lit-up battery warning light on the dash.

Toyota Land Cruiser Alternator Problems

The alternator is for charging the battery from the engine while the vehicle is running. A defective alternator can certainly prevent your Toyota Land Cruiser from starting as it wont be able to charge up the battery, from the engine, so it will drain fairly quickly till it's completely drained and you only realize it when you get in your Land Cruiser and it won't start. Signs that your car's alternator is faulty can be a lit-up battery or alternator warning 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 Land Cruiser Starter Motor Failures

When you start your Toyota Land Cruiser, the starter motor is responsible for turning the engine over (cranking it). If the starter motor is defective in some way then the engine may not crank, and your Land Cruiser won't start. You can find out if your starter motor has an issue or not typically by listening for a clicking noise when you turn the key in the ignition or a grinding noise during the startup, or your car only starts intermittently then the starter motor may very well be the problem.

Toyota Land Cruiser Fuel System Complications

Now we're not talking about when you merely run out of gas here, but the fuel system itself having issues. Your Toyota Land Cruiser uses a combustion engine, and because of this to start and run, it needs a combination of both fuel and air. If your Land Cruiser issues are part of a faulty fuel system, this can sometimes be a clogged fuel filter or a failing fuel pump relay, which could suggest the engine may not be getting the fuel it requires to get the car going.

Toyota Land Cruiser Electrical System or Wiring Problems

Modern Toyota Land Cruisers rely heavily on electronic components, which can mean there are lots of things that can potentially break. Even in an older car, you can still have typical problems such as blown fuses, spark plug problems, a faulty ignition switch, or a faulty sensor, and more. These can be some of the various electrical reasons why your car can't start. Indications of a wiring or electrical issue can vary greatly but can often include the engine not cranking, or your Land Cruiser can start but just intermittently or numerous warning lights come on the dashboard. To properly diagnose and fix these kinds of issues, you will need the skills of a skilled car mechanic locally or online.

Solutions & Repair Tips

As soon as you have figured out what the reason for your car failing to start is. The next step is obviously to attempt to fix it. Here are some tips for the typical problems we've covered up until now.

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

If it’s a battery issue you suspect is the problem, then the first thing you should do is inspect the battery terminals. You want them to be clean, not corroded, and securely connected. If you find that the terminals are corroded you can try to clean them up with a mix of baking soda and water. You will need to replace the battery if it's weak or old, otherwise, even if you charge it up enough to start the vehicle, it will likely die again in the near future. You can make use of a multimeter as a battery tester to see if it’s worth saving or if it needs to be changed for a new one. You can ask a reliable car mechanic online or locally to best advise you on this.

If the alternator is what you think is the cause, you can test it to see for yourself. If you can get the vehicle started temporarily (you may need to jump-start the car for that), but once it’s going, let the car run, and while the engine is running, disconnect the positive terminal of the battery. It's most likely due to a fault with the alternator if you find your Toyota Land Cruiser dies right away when you disconnect the positive terminal. However, be warned this test can be risky if you don't know what you're doing, and might damage the sensitive electronic elements in your vehicle, so in this case best to consult with an experienced mechanic local to you or online, before ever attempting this.

How to Identify Starter Motor Failures in a Toyota Land Cruiser

Listen for a clicking sound when you turn the key in the ignition or press the start button if you suspect the starter motor is the cause of your Toyota Land Cruiser not starting. In this case, the solution is to have the starter motor replaced by a professional mechanic.

How to Fix Fuel System Problems in a Toyota Land Cruiser

If you think the issue to be because of a fuel system problem, try and listen for the fuel pump when you turn the key to the “on” position, before starting up the vehicle. You should hear a humming noise for a few seconds. If you are unable to hear this noise, then it might be there is cause for concern with the fuel pump. If you notice your Toyota is hard to start, it stalls, or it has bad acceleration, it might be due to a clogged fuel filter. Both of these will likely require a reliable car mechanic in order to correctly repair.

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

If your Toyota Land Cruiser starts after this, then it was an effective, simple and cheap fix! However, if the car does not start, even intermittently it could be an issue with the ignition switch itself. It may be a faulty sensor if various warning lights are visible on the dash. These problems can be very intricate and a professional car mechanic is most likely needed to identify and have it properly repaired.

Preventive Steps

Drive Your Toyota Land Cruiser Frequently:

If you happen to leave your Toyota Land Cruiser in the driveway for extended periods of time without driving it, the battery will drain as it's not receiving any electrical charge from the engine running running regularly. Try your best to drive your vehicle frequently to keep the battery charged up. 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 in a while. 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:

If you notice anything odd like uncommon noises, changes in how it drives and the performance, or alert lights showing on the dash, don’t just disregard them.
