Your car starting only in neutral but not in park may indicate a faulty neutral safety switch. This switch prevents the car from starting in gear for safety reasons.
Having trouble starting your car in park but not neutral could be due to an issue with the neutral safety switch. This component ensures that the vehicle can only be started in neutral or park, preventing any accidental movement while the engine is running.
If the neutral safety switch is malfunctioning, it may not recognize that the car is in park, leading to starting issues. By understanding how this switch works, you can diagnose and potentially fix the problem to ensure your car starts smoothly in both neutral and park.
Common Issue With Starting In Park
If you’ve ever experienced the frustration of your car only starting in neutral but not park, you’re not alone. This is a common issue that many car owners face, and it can be quite perplexing. Fortunately, there are a few common culprits that could be causing this problem. In this post, we’ll explore two of the most common reasons why your car won’t start in park and what you can do to fix it.
Faulty Neutral Safety Switch
A faulty neutral safety switch is often the root cause of starting issues in park. This switch is designed to prevent the car from starting unless it is in neutral or park, ensuring that the vehicle doesn’t accidentally move while starting. However, over time, the neutral safety switch can become worn out or malfunction, resulting in the car not recognizing that it is in park.
If you suspect that the neutral safety switch is the culprit, you can try a few troubleshooting steps. First, check if the car starts consistently in neutral but not in park. If this is the case, it strengthens the likelihood of a faulty neutral safety switch. Secondly, check for any visible signs of damage or corrosion on the switch itself. If you notice any issues, it may be necessary to replace the switch to restore proper functionality.
Worn Ignition Switch
Another common cause of starting problems in park is a worn ignition switch. The ignition switch is responsible for sending power to various systems in the car, including the starter motor. When the ignition switch becomes worn, it may not make proper contact in the park position, preventing the car from starting.
To determine if the ignition switch is to blame, you can perform a simple test. Start by turning the key to the “on” position and then shifting the gear from park to neutral. If the car starts in neutral but not in park, it’s a strong indicator of a worn ignition switch. In this case, it may be necessary to replace the ignition switch to resolve the issue.
Remember, when dealing with electrical components and car repairs, it’s always best to consult a professional mechanic for an accurate diagnosis and proper repair. They have the expertise and tools necessary to fix the issue efficiently and safely.

Signs Of A Faulty Neutral Safety Switch
A neutral safety switch is a crucial component of your vehicle’s starting system. When it malfunctions, it can cause your car to only start in neutral but not in park. Recognizing the signs of a faulty neutral safety switch can help you diagnose and address the issue promptly, ensuring the continued reliability of your vehicle.
Car Starts In Neutral But Not In Park
If your car starts in neutral but does not respond when the transmission is in the park position, it may indicate a faulty neutral safety switch. This switch is designed to prevent the engine from starting while the transmission is in gear, ensuring safe operation of the vehicle. When it fails, the car may only start in neutral, as the switch is bypassed in this position.
No Response When Turning Ignition In Park
Another indication of a faulty neutral safety switch is no response when turning the ignition in park. If you experience difficulty starting the car or no response from the engine when the transmission is in the park position, the neutral safety switch could be the culprit. This issue may pose a significant safety concern and should be addressed immediately.
Signs Of A Worn Ignition Switch
If your car only starts in neutral but not park, one possible culprit could be a worn ignition switch.

Causes Of Neutral Safety Switch Failure
A common cause of a car only starting in neutral but not park is a failure of the neutral safety switch. This switch ensures that the vehicle can only be started in neutral or park for safety reasons. When it malfunctions, it can prevent the car from starting in the park position.
Electrical Malfunction
Inconsistent power supply can cause the neutral safety switch to fail electrically.
Mechanical Wear And Tear
Over time, constant usage can lead to mechanical damage and affect the switch’s functionality.
Steps To Diagnose And Fix The Issue
If your car only starts in neutral but not in park, it can be frustrating and inconvenient. However, diagnosing and fixing this issue does not have to be a complicated process. By following the steps below, you can identify the underlying problem and take the necessary steps to resolve it.
Check The Neutral Safety Switch With A Multimeter
To begin the diagnosis, the neutral safety switch needs to be tested using a multimeter. This safety switch is designed to prevent the engine from starting unless the transmission is in neutral or park. A malfunctioning switch can cause the engine to start only in neutral. To check the switch, follow these steps:
- Locate the neutral safety switch, typically located near the base of the steering column or on the transmission.
- Disconnect the electrical connector from the switch.
- Set the multimeter to the continuity test mode.
- Connect the multimeter probes to the switch terminals and check for continuity when the transmission is in neutral and park.
- If there is no continuity in either neutral or park, the neutral safety switch may need to be replaced.
Inspect And Replace The Ignition Switch
If the neutral safety switch is functioning properly, the next step is to inspect the ignition switch. A faulty ignition switch can also cause the car to start only in neutral. Here’s how to proceed:
- Locate the ignition switch, usually located on the steering column or dashboard.
- Check for any visible signs of damage or wear on the switch.
- If no visible issues are present, use a multimeter to test the switch for continuity.
- If the ignition switch fails the continuity test, it may need to be replaced.
