Is your Nissan Murano refusing to start when you need it most? It’s frustrating, confusing, and can leave you feeling stuck.
You might be wondering what’s wrong and how to fix it quickly. Understanding the common reasons behind this problem can save you time, money, and stress. Keep reading to discover why your Nissan Murano isn’t starting and what you can do right now to get back on the road.
Common Reasons For No Start
When your Nissan Murano won’t start, it can be frustrating. Several common issues cause this problem. Understanding these can help you identify the cause quickly. Here are the main reasons why your Murano might not start.
Dead Or Weak Battery
The battery provides power to start the engine. A dead or weak battery can stop your Murano from starting. Cold weather or leaving lights on can drain the battery. Sometimes, old batteries lose their charge and need replacement.
Faulty Starter Motor
The starter motor turns the engine over to start it. If the starter motor is faulty, the engine won’t crank. You may hear a clicking sound or no sound at all. A bad starter motor needs repair or replacement.
Ignition Switch Issues
The ignition switch sends power to the starter and other systems. A broken ignition switch can prevent the Murano from starting. Sometimes, the key won’t turn or the dashboard lights won’t come on. Replacing the ignition switch often fixes this.
Fuel System Problems
The engine needs fuel to start and run. Fuel pump failure or clogged fuel filters can block fuel flow. Low fuel levels or bad fuel can also cause starting issues. Checking the fuel system is important if the engine cranks but won’t start.
Engine Immobilizer Malfunction
The engine immobilizer prevents theft by blocking the engine start. If the immobilizer system malfunctions, it may not recognize your key. This stops the engine from starting. Resetting or repairing the immobilizer system can solve this problem.

Battery Troubleshooting
Battery problems often cause a Nissan Murano not to start. The battery gives power to the engine and other parts. Checking the battery is the first step in fixing starting issues. Simple battery care can save you a trip to the mechanic. Let’s explore easy ways to check and fix your Murano’s battery troubles.
Checking Battery Charge
Use a voltmeter to check the battery’s charge. A healthy battery shows about 12.6 volts or more. Below 12.4 volts means the battery may be weak. Turn off the engine before testing. If the voltage is low, the battery might need charging or replacement.
Cleaning Battery Terminals
Dirty or corroded terminals stop the battery from working well. Look for white or greenish buildup on the terminals. Use a wire brush or baking soda mixed with water to clean them. Make sure the terminals are tight after cleaning. Clean terminals help the battery connect properly to the car.
Jump-starting Your Murano
Jump-starting can help if the battery is dead. Use jumper cables and a working car’s battery. Connect the red cable to the positive terminal on both batteries. Connect the black cable to the negative terminal on the good battery and a metal part on your Murano. Start the working car first, then your Murano. Let the engine run to charge the battery.
Starter And Ignition Fixes
The starter and ignition system play a key role in starting your Nissan Murano. Problems here often stop the engine from turning on. Checking these parts can help find the issue quickly. Simple fixes might get your car running again without much cost.
This section explains how to test the starter motor and replace the ignition switch. Clear steps make it easy to follow and understand. Keep your Murano ready to start every time.
Testing The Starter Motor
The starter motor sends power to the engine to start it. If it fails, the engine won’t turn over. First, listen for a clicking sound when turning the key. No sound may mean a bad starter.
Use a multimeter to check voltage at the starter. Low or no voltage means a wiring or battery problem. If voltage is good, the starter motor itself might be faulty. Testing helps avoid replacing parts unnecessarily.
Replacing The Ignition Switch
The ignition switch sends power to the starter and other systems. A worn switch can stop the car from starting. Signs include no dashboard lights or the engine not cranking.
Replace the ignition switch by disconnecting the battery first. Remove the steering column covers to access the switch. Disconnect old switch wiring and install the new part carefully. Test the new switch to confirm the fix.
Fuel Delivery Solutions
Fuel delivery issues often cause a Nissan Murano not to start. The engine needs a steady flow of fuel to run. Problems with the fuel pump or filter can block this flow. Fixing these parts can solve the starting problem fast.
Inspecting Fuel Pump
The fuel pump sends fuel from the tank to the engine. If it stops working, the engine gets no fuel. Listen for a humming sound near the fuel tank when turning the key. No sound may mean a bad pump. A mechanic can test the pump pressure. Replace the pump if it fails the test.
Clearing Clogged Fuel Filter
The fuel filter cleans dirt from the fuel. Over time, it can clog and block fuel flow. A clogged filter makes starting hard or impossible. Replace the fuel filter regularly to avoid this problem. Check the filter if the engine sputters or stalls. Cleaning or changing the filter can restore fuel flow.
Immobilizer And Key Issues
The immobilizer system in your Nissan Murano stops the engine from starting without the right key. This security feature helps prevent theft. Sometimes, the car does not start because of problems with the immobilizer or the key. Common issues include a dead key battery, key damage, or a system glitch.
Understanding how to handle immobilizer and key issues can save time and frustration. Simple steps like resetting the immobilizer or using a spare key may fix the problem. These actions help the car recognize your key and allow the engine to start.
Resetting The Immobilizer
Resetting the immobilizer can fix system errors. Start by locking and unlocking the car doors with the key fob. Then, insert the key into the ignition and turn it to the “on” position without starting the engine. Leave it like this for about 10 minutes. This process helps the system reset and recognize the key.
After waiting, turn the key off and try starting the car again. If the problem continues, repeat the steps once more. This simple reset can often restore communication between the key and immobilizer.
Using A Spare Key
A damaged or weak key can cause starting problems. Testing a spare key helps identify if the original key is faulty. Use the spare key to unlock the doors and start the engine. If the car starts, the original key may need a new battery or replacement.
Spare keys often avoid immobilizer issues because they have fresh batteries and no damage. Keep a spare key ready for emergencies. It is a simple way to check if the immobilizer system or key is the cause of the no-start problem.

Knowing when to seek professional help for your Nissan Murano is crucial. Some car problems need expert attention to avoid further damage. If your Murano won’t start after basic checks, it’s time to call a mechanic. Professionals can find hidden issues quickly and fix them safely.
Diagnostic Tools And Scans
Mechanics use special diagnostic tools to find car problems. These tools read error codes from your car’s computer. They show exactly what part is causing the problem. A scan can detect issues with the battery, starter, or sensors. This saves time and avoids guessing. The right tool helps fix your Murano the first time.
Finding A Trusted Mechanic
Choose a mechanic who knows Nissan cars well. Experienced professionals understand Murano’s unique systems. Check reviews and ask friends for recommendations.
