## My Car Engine Won’t Turn Over
If your car engine won’t turn over, it can be a frustrating and stressful experience. There are a number of potential causes for this problem, and depending on the underlying issue, the cost to repair it can vary significantly.
This article will provide you with an overview of the most common reasons why a car engine won’t turn over, as well as some troubleshooting tips and potential repair costs.
### Common Causes of a Car Engine Not Turning Over
**1. Dead Battery**
A dead battery is one of the most common reasons why a car engine won’t turn over. This can be caused by a number of factors, such as leaving your headlights on overnight, a faulty alternator, or a parasitic drain on the battery.
**2. Faulty Starter**
The starter is responsible for turning the engine over. If the starter is faulty, it will not be able to engage the flywheel and start the engine. This can be caused by a number of factors, such as a bad solenoid, worn brushes, or a damaged armature.
**3. Bad Ignition Switch**
The ignition switch is responsible for sending power to the starter. If the ignition switch is faulty, it will not be able to complete the circuit and start the engine. This can be caused by a number of factors, such as a worn key cylinder, a damaged wiring harness, or a faulty ignition module.
**4. Faulty Neutral Safety Switch**
The neutral safety switch prevents the engine from starting if the transmission is not in park or neutral. If the neutral safety switch is faulty, it will not be able to complete the circuit and start the engine. This can be caused by a number of factors, such as a worn or damaged switch, a faulty wiring harness, or a problem with the transmission.
**5. Fuel System Problems**
If there is a problem with the fuel system, the engine will not be able to get the fuel it needs to start. This can be caused by a number of factors, such as a clogged fuel filter, a faulty fuel pump, or a leak in the fuel line.
### Troubleshooting Tips
If your car engine won’t turn over, there are a few things you can do to troubleshoot the problem:
1. **Check the battery.** Make sure the battery terminals are clean and tight. You can also try jump-starting the car to see if that solves the problem.
2. **Check the starter.** If the battery is good, the next step is to check the starter. You can do this by tapping the starter with a hammer while someone tries to start the car. If the car starts, the starter is likely faulty and will need to be replaced.
3. **Check the ignition switch.** If the starter is good, the next step is to check the ignition switch. You can do this by turning the key to the “on” position and listening for a clicking sound. If you don’t hear a clicking sound, the ignition switch is likely faulty and will need to be replaced.
4. **Check the neutral safety switch.** If the ignition switch is good, the next step is to check the neutral safety switch. You can do this by putting the transmission in park or neutral and trying to start the car. If the car starts, the neutral safety switch is likely faulty and will need to be replaced.
5. **Check the fuel system.** If the starter, ignition switch, and neutral safety switch are all good, the next step is to check the fuel system. You can do this by checking the fuel filter for clogs and the fuel pump for proper operation.
### Potential Repair Costs
The cost to repair a car engine that won’t turn over will vary depending on the underlying cause of the problem. Here is a general overview of the potential repair costs for each of the common causes:
* **Dead battery:** The cost to replace a dead battery typically ranges from $100 to $250.
* **Faulty starter:** The cost to replace a faulty starter typically ranges from $200 to $500.
* **Bad ignition switch:** The cost to replace a bad ignition switch typically ranges from $150 to $300.
* **Faulty neutral safety switch:** The cost to replace a faulty neutral safety switch typically ranges from $100 to $250.
* **Fuel system problems:** The cost to repair fuel system problems can vary significantly depending on the specific issue. However, you can expect to pay anywhere from $100 to $1,000 for repairs.
