In the vast majority of cases, the most common reason why your Infiniti won’t start is often the result of your battery, it’s either dead or weak, and you have to either recharge the battery or change it. The vehicle’s battery provides the power needed to start the engine, and power all the electrical parts in your Infiniti. Symptoms of a weak or dead battery issue in a Infiniti, can be things like the car being sluggish to crank the engine, weak or dim headlights, or a lit-up battery caution light on the dashboard. A portable jump starter allows you to jump start your car if the battery is dead without needing another vehicle, and a battery charger can help recharge a dead battery and diagnose battery issues.

Alternator Issues Can Cause Infiniti Starting problems

The alternator is responsible for charging the battery from the engine while the vehicle is running. A defective alternator can easily stop your Infiniti 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 totally dead and you only realize it when you get into your beloved Infiniti and it refuses to start. Signs that your cars alternator may be faulty can be a lit up battery or alternator warning light on the dashboard, dim headlights when the engine is idling, and also a whining or grinding sound from the engine while it’s running.

Infiniti Starter Motor Failures

my car wont start is the starter motor?

When you start your Infiniti, the starter motor is responsible for turning the engine over (cranking it). If the starter motor is failing in some manner then the engine will not crank, and your Infiniti wont start. You can find out if your starter motor has a problem or not often by listening, if you hear a clicking noise when you turn the key in the ignition or a grinding noise throughout the start-up, or your vehicle only starts intermittently then the starter motor may very well be the problem.

Infiniti Fuel System Complications

Your Infiniti uses a combustion engine, and for that reason to start and run, it needs a mix of enough fuel and air. If your Infiniti problems are because of a faulty fuel system, this could be a clogged fuel filter or a damaged fuel pump relay, which could indicate the engine may not be receiving the fuel it needs to get the car up and running.

Infiniti Electrical System or Wiring Problems

These can be some of the numerous electrical examples of how failing electrical components can be the reason your vehicle wont start up.

Solutions & Repair Tips For When Your Infiniti Can’t Start

As soon as you have figured out what the reason for your Infiniti troubles are. The next logical step is naturally 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 Infiniti

If you suspect it’s possibl a battery issue is the reason your Infiniti has trouble starting up, then the first thing you ought to do is check around the battery and check 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 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 just out of charge, or worse, it’s old and 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 deplete quickly once again in the near future. You can make use of 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 replacing. You can get a replacement car battery for your exact Infiniti model by visiting Amazon here, and selecting “enter a new vehicle” to filter the results for your Infiniti, and choose a suitable one, from a seller with great reviews.

If charging your Infiniti’s car 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.

How to Diagnose Alternator Problems in a Infiniti

If the alternator is what you think is the reason, you can test it. 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 vehicle run, and while its running, disconnect the positive terminal of the battery. It’s most likely due to a fault with the alternator if you discover your Infiniti dies pretty quickly when you disconnect the positive terminal. You should be aware however that this method can be risky, and might damage the sensitive electronic parts in your Infiniti, so it’s best to consult with a professional car mechanic in your area or online, prior to ever trying this.

How to Identify Starter Motor Failures in a Infiniti

If you hear the clicking sound when you try and start the car by turning the key, however the engine doesn’t crank, then its most likely an issue with your starter motor. In these cases, the solution is to have the starter motor changed for a new one by a professional mechanic.

How to Resolve Fuel System Issues in a Infiniti

If you think the issue to be due to a fuel system problem, listen for the fuel pump when you turn the key to the “on” position, before starting up the car. You should be able to hear a humming noise for a couple of seconds. It may be there is an issue with the fuel pump if you are unable to hear this noise. If you notice your Infiniti is hard to start, it stalls, or it has bad acceleration, it could possibly be down to a clogged fuel filter. Both of these will likely need a reliable car mechanic in order to effectively repair.

How to Fix Electrical or Wiring Issues in a Infiniti

If you suspect it’s a wiring or electrical system issue, initially examine the fuses associated with the ignition system, and change any that have blown. If your Infiniti starts after this, then it was a successful, easy and inexpensive fix! Nevertheless, if the vehicle doesn’t start, even intermittently it could be a problem with the ignition switch itself. If various warning lights show up on your dashboard, it might be due to a broken sensor. These issues can be extremely complicated and a professional car mechanic is most likely required to identify and have it properly repaired.

How To Prevent Infiniti No Starting Issues

As my father always said “Prevention is better than cure”, so here are the best ways to make sure you avoid any Infiniti starting problems again!

Routine Maintenance of Your Infiniti:

Regular maintenance on car to prevent starting issues

Regular maintenance of your Infiniti is crucial to avoiding future difficulties. This consists of things like regular oil changes, checking the battery, cleaning up the terminals, changing the fuel filter as recommended/required, and of course having your vehicle checked by a reliable car mechanic routinely. You can consult a mechanic locally or online if you find yourself unsure or confused about the routine upkeep tasks needed for your specific vehicle.

Drive Your Infiniti Regularly:

If you happen to leave your Infiniti in the driveway for long periods of time without taking it for a spin now and again, the battery can run out of charge as it’s not getting any charge from the engine being in use. Try to drive your vehicle frequently to keep the battery charged up. 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 fully drain, is also damaging for the longevity of the battery, try not to do this.

Take Notice Of Warning Signs:

Check Engine Control Light on a Vehicle Dashboard

If you notice anything strange like unusual noises, changes in how it drives and the performance, or alert lights are now visible on the dash, don’t just ignore them. These are usually early indications of a problem and are best being resolved ASAP so that they don’t end up being larger issues later. Talk to a car mechanic in your area or online about these issues and find out if they need to be attended to.

When to Ask a Infiniti Mechanic Online
