Auto Start Nissan Altima 2017

Hello Altima owners! Having trouble getting your 2017 Nissan Altima to start? You're not alone. The 2017 Altima, while generally reliable, can sometimes present starting issues. Let's explore some common culprits and get you back on the road.
Common Starting Problems in the 2017 Nissan Altima
Several factors can prevent your 2017 Altima from starting. It's helpful to diagnose the problem before heading to the repair shop, as it can save you time and money. Here are some of the most frequent causes:
1. Dead or Weak Battery
This is the most common reason for a no-start condition. Batteries degrade over time, especially in extreme temperatures. If your Altima is cranking slowly or not at all, suspect the battery first.
Solution:
- Jump Start: If you have jumper cables and another vehicle, try jump-starting your Altima. Make sure to follow the correct procedure to avoid damaging your vehicle's electrical system.
- Battery Testing: Use a multimeter to check the battery voltage. A healthy battery should read around 12.6 volts. If it's significantly lower, it's likely the battery is the problem. Many auto parts stores offer free battery testing services.
- Battery Replacement: If the battery is dead or weak, replace it with a new one. A new battery for your Altima will typically cost between $100 and $250, depending on the brand and type. Tools needed: Socket set, wrench, battery terminal cleaner.
- Check the Alternator: A failing alternator can prevent the battery from charging properly, leading to a dead battery. After jump-starting your car, have the alternator tested to ensure it's charging correctly.
2. Faulty Starter Motor
The starter motor is responsible for cranking the engine. If you hear a clicking sound when you turn the key, but the engine doesn't crank, the starter motor could be failing.
Solution:
- Starter Relay Check: Locate the starter relay in the fuse box (consult your owner's manual for the location). Swap it with a similar relay and see if the car starts. If it does, the relay was the problem. A new relay is relatively inexpensive (around $10-$30).
- Starter Motor Replacement: If the relay is fine, the starter motor itself is likely the issue. Replacing the starter motor can be a bit more involved and might require some mechanical skills. The part itself can cost between $150 and $400, and labor can add another $100-$300. Tools needed: Socket set, wrench, jack and jack stands (for safety). Consider having a professional mechanic handle this repair if you're not comfortable working on your car.
3. Issues with the Ignition System
The ignition system provides the spark needed to ignite the fuel in the engine. Problems with the ignition system can prevent your Altima from starting.
Solution:
- Spark Plugs: Worn or fouled spark plugs can cause starting problems. Inspect the spark plugs and replace them if necessary. Spark plugs typically cost between $5 and $20 each, and replacing them is a relatively easy DIY task. Tools needed: Spark plug socket, ratchet, extension.
- Ignition Coils: Faulty ignition coils can also prevent the engine from starting. You can test the ignition coils using a multimeter. If one or more coils are bad, replace them. Ignition coils can cost between $50 and $150 each. Tools needed: Multimeter, socket set.
- Crankshaft Position Sensor: This sensor tells the engine control unit (ECU) the position of the crankshaft. A faulty crankshaft position sensor can prevent the engine from starting. Replacing this sensor is typically best left to a professional, as it can be difficult to access.
- Ignition Switch: Although less common, the ignition switch itself could be faulty. Try wiggling the key in the ignition while attempting to start the car. If this helps, the ignition switch might need to be replaced.
4. Fuel System Problems
The fuel system delivers fuel to the engine. Problems with the fuel system can starve the engine of fuel, preventing it from starting.
Solution:
- Fuel Pump: The fuel pump is responsible for delivering fuel from the fuel tank to the engine. A failing fuel pump can cause starting problems, especially when the engine is cold. You might hear a whining sound from the fuel tank when you turn the key if the fuel pump is failing. Replacing the fuel pump can be a complex job and is often best left to a professional. The part itself can cost between $150 and $400, and labor can add another $200-$500.
- Fuel Filter: A clogged fuel filter can restrict fuel flow to the engine. Replacing the fuel filter is a relatively inexpensive and easy DIY task. The fuel filter typically costs between $20 and $50. Tools needed: Wrench, fuel line disconnect tool.
- Fuel Injectors: Dirty or clogged fuel injectors can also cause starting problems. You can try cleaning the fuel injectors using a fuel injector cleaner additive. If that doesn't work, you might need to have the fuel injectors professionally cleaned or replaced.
5. Security System Issues (Immobilizer)
The immobilizer is a security system that prevents the car from starting if the correct key isn't used. Sometimes, the immobilizer can malfunction, preventing the car from starting even with the correct key.
Solution:
- Check the Key Fob Battery: A weak key fob battery can sometimes interfere with the immobilizer system. Try replacing the battery in your key fob.
- Resync the Key Fob: Consult your owner's manual for instructions on how to resync the key fob with the car.
- Immobilizer Reset: In some cases, the immobilizer might need to be reset by a qualified mechanic. This often requires specialized diagnostic equipment.
6. Other Potential Causes
While the above are the most common causes, other issues can also contribute to starting problems:
- Flooded Engine: If you've repeatedly tried to start the car without success, you might have flooded the engine. To clear a flooded engine, hold the accelerator pedal all the way down while cranking the engine for a few seconds.
- Vacuum Leaks: Vacuum leaks can disrupt the air-fuel mixture, making it difficult for the engine to start.
- Engine Control Unit (ECU) Issues: In rare cases, a faulty ECU can prevent the engine from starting. This is usually diagnosed by a professional mechanic using specialized diagnostic equipment.
Troubleshooting Steps
Here's a systematic approach to diagnosing the starting problem in your 2017 Nissan Altima:
- Listen Carefully: Pay attention to the sounds the car makes when you turn the key. Do you hear clicking? Does the engine crank slowly or not at all?
- Check the Battery: Use a multimeter to check the battery voltage.
- Inspect the Fuses and Relays: Check the fuses and relays related to the starting system. Your owner's manual will have a fuse box diagram.
- Try a Jump Start: If the battery seems weak, try jump-starting the car.
- Consult Your Owner's Manual: Your owner's manual contains valuable information about your car, including troubleshooting tips.
When to Seek Professional Help
If you've tried the above steps and your 2017 Altima still won't start, it's time to seek professional help from a qualified mechanic. They have the diagnostic tools and expertise to accurately diagnose the problem and perform the necessary repairs. Don't hesitate to consult a professional, especially if you're uncomfortable working on your car or if you suspect a more complex issue.
Approximate Repair Costs:
It's difficult to give exact repair costs without knowing the specific problem. However, here are some rough estimates:
- Battery Replacement: $100 - $250
- Starter Motor Replacement: $250 - $700 (including labor)
- Spark Plug Replacement: $50 - $200 (including labor)
- Fuel Pump Replacement: $350 - $900 (including labor)
These are just estimates, and the actual cost may vary depending on the shop and the specific parts used.
