6 Easy Fix For Jeep Wrangler Won’t Start But Battery Is Good
You now have a foundational knowledge of the potential reasons your Jeep Wrangler won’t start problems-based on the points previously given. This section will go through these issues when they arise, potential repair costs, and complete solutions.
#1- Check Fuel Quantity:
If your jeep is not starting though the battery is in good condition, you must check its fuel level first. If you notice that the fuel level is too low, you must refuel it. Otherwise, you won’t be able to start it.
You can refuel your jeep from any nearest station easily; its cost depends mainly on which type of fuel your jeep uses and the area where you live.
#2- Examine And Repair Faulty Starters.
The starter itself consists of a tiny motor that runs on battery power. The starter creates suction to turn the engine over. In addition, a set of electrical components manages the starting motor.
Even when the starter works properly but any of these parts malfunction, your Wrangler won’t start.
Here are several indications that may help you determine that the starter has problems.
- Noises: If you notice whining, clicking, or grinding noise when you try to start your jeep, you can be sure that the starter has problems.
- Smoke: This is another indication of a faulty starter. If you notice that the smoke is coming out from the engine, it indicates that the starter is totally blown up.
If you are sure that the starter is malfunctioning, there is no other way to solve this problem without changing it. Follow these given step-by-step procedures to change it successfully.
- Step 1: Find the starter and unplug it from all the connections. Detach the solenoid connector as well.
- Step 2: Remove the bolts which hold the starter in place and carefully take out the starter module.
- Step 3: Change it out with a new one, then reconnect everything.
If you decide to replace it, it will cost you between $300 and $400. However, hiring a professional technician costs you between $400 and $500.
#3- Replace The Defective Ignition Switch.
One of the most critical parts of your Jeep Wrangler is the ignition switch. If it malfunctions, the entire car won’t be able to move. Various problems might result from a bad ignition. These include stalling problems, starting difficulties, and radio or accessory power issues.
In your Jeep Wrangler, the following are a few of the typical signs of an ignition system failure:
- The engine won’t start: If your ignition switch is malfunctioning, no matter what you do, the Wrangler won’t start.
- Stop while driving: Stalling is the most obvious sign of a broken ignition switch. Whenever this occurs, the engine won’t be able to operate until it has been completely replaced.
- Starts but fails: It’s a pretty good sign that perhaps the ignition switch is damaged if your Jeep Wrangler starts and suddenly stops within a few seconds.
The ignition switch may be readily replaced to solve this issue. Although it’s not a simple process, you can change the ignition switch yourself. An experienced technician should be used for this. And this will cost you between $135 and $150.
#4- Fix Defective Alternator.
The alternator maintains the battery’s voltage to power the car’s subsystems. When your Jeep’s alternator fails, driving on the road might be risky because of the increased chance of failure.
The most typical indications of a damaged alternator in a Jeep Wrangler are as follows:
- The battery alarm system blinks.
- Devices will not charge.
- Reduce the interior and headlights brightness.
- The automobile is having difficulty starting.
- After starting, the car emits a whining or screaming sound.
- Under the bonnet, there is a strong odor of burning rubber.
The only way to address this problem is to replace the defective one, which can cost between $433 and $657.
#5- Replace Faulty Starter Relay.
It would be impossible to start a jeep ordinarily without the usage of the starting relay. When you turn the key in on position, the starter relay engages, and the engine starts.
This connects your ignition switch, starting motor, and fuel pump to the power supply. If the starting relay is faulty, the starter motor will not turn on.
The following are the primary signs of a faulty starter relay:
- The vehicle will not start.
- Clicking sounds.
- The starter motor operates continuously.
To resolve this issue, you must replace the defective relay with a new one. And this starting relay repair typically costs between $62 and $71.
#6- Locate And Replace Damaged Fuses.
Fuses are another crucial tiny component in a jeep wrangler. Sometimes, these fuses can be blown for several reasons like over-voltage, water damage, etc. When one of these fuses gets damaged or blown out, it prevents the engine from starting.
To solve this problem, just locate and replace the damaged fuse. Here the replacement fuse must have to match the previous one; otherwise, it won’t work.
Replacing a damaged fuse is so easy if you follow these procedures.
- Step 1: First, locate the damaged fuse and take it out by hand or with any tools.
- Step 2: Set the new fuse and press it down until it is firmly set up.
If you replace it yourself, it will cost you around $4 to $6. But, if you take a technician’s help, you have to pay an additional $90 to $100 for labor costs.

Your Jeep Wrangler making clicking noises and not starting might be due to several different things. Start by examining the most obvious, simple-to-diagnose issues, such as loose connections and fuel quantity, when you’re trying to figure out why.
