Jeep Wrangler Won’t Start – What Could Be Wrong?

Let’s face it, when your vehicle won’t start, it’s a huge inconvenience and, to be honest, it stinks. What’s worse is not knowing why it won’t start and having to troubleshoot to figure out what’s wrong.

The Jeep Wrangler is distinct from other gas vehicles, but it is similar in that it has a battery, an engine, and requires fuel to operate. Examining each of these vehicle components will help you assess and diagnose why your vehicle won’t start.

Let’s look at each possible explanation, beginning with the most common.

Dead Battery

A dead battery is the most common reason a newer vehicle, such as the Jeep Wrangler, will not start. This could be caused by leaving your lights on overnight and allowing the battery to run out of power.

If you turn the key to start your car and it makes an instant click sound, your battery is most likely dead. Start the car with jumper cables, and then let it run for ten minutes to allow the battery to recharge.

If the battery discharges again soon after the vehicle is turned off, it may need to be replaced. Take your vehicle to a local auto parts store or mechanic to have the battery tested to see if it needs to be replaced.

Bad Key Fob Battery

A faulty key fob battery could also be the cause of your Jeep Wrangler not starting. If your vehicle has a push-button start, a dead battery in the fob could be the problem. If this is the case, don’t worry; there are still ways to start the vehicle.

If the key fob’s battery dies, you must manually unlock the vehicle’s doors. Place the key fob as close to the push to start button as possible and try starting the vehicle. If that doesn’t work, consult your owner’s manual for alternative methods of starting the vehicle.

Alternator Replacement

A bad alternator is another common cause of the car not starting. An alternator is responsible for keeping the battery charged. If the battery has been tested and found to be in good working order, the problem could be with the alternator.

Start the vehicle and disconnect the positive cable from the battery to test the alternator. If the car shuts down, the alternator most likely needs to be replaced.

Starting the vehicle and turning on the interior lights is another quick way to check the alternator. If the interior lights begin to fade gradually, the alternator is most likely failing to keep the battery charged.

Starter Replacement

The starter spins the engine, allowing it to be started with the ignition key. The vehicle cannot run without a properly functioning starter. In all makes and models, bad starters are a common problem. If you turn the key and hear a click sound but the engine does not start, it is likely that the starter needs to be replaced.

Typically, starters do not need to be replaced until 75,000 to 125,000 miles, but that does not mean it cannot fail on your Jeep Wrangler sooner. If the starter fails, the vehicle will not start and must be towed to a mechanic shop.

Ignition Switch Replacement

The ignition switch is a component of the charging, starting, and ignition systems. When the ignition switch is turned on, these systems are activated, allowing the vehicle to run. Consider the ignition switch to be the power switch for the car’s electronic components, as it is required for the vehicle to start.

If the air conditioner fails to work or starts but abruptly stops while driving, it could be due to a faulty ignition switch. A certified mechanic should inspect the ignition switch right away to avoid further damage or injury.

Fuel Pump Replacement

The fuel pump is in charge of transferring gas from the fuel tank to the fuel injectors. For the vehicle to run properly, the fuel pump must transfer the correct amount of gas at the correct pressure.

If the fuel pump is leaking or making a lot of noise, it may be faulty and should be replaced right away. A faulty fuel pump could cause the engine to lose power and fail to start at all. It is not recommended to drive the vehicle with a bad fuel pump and instead call a tow truck or a mobile mechanic.

Final Thoughts

While the Jeep Wrangler is designed for more than just daily commuting, it will encounter issues from time to time. If your Jeep Wrangler won’t start, the best thing to do is troubleshoot the problem. However, if you reach the point where you believe the problem is beyond your abilities, contact a Jeep mechanic for assistance.
