Why is my Chevy Equinox turning over but not starting?
If your Chevy Equinox is turning over but not starting, it can be a frustrating experience. This issue often indicates that while the starter motor is functioning and attempting to crank the engine, there is an underlying problem preventing the engine from firing up. In this article, we’ll explore the most common causes of this issue and provide guidance on how to address them.
Common Causes of a Chevy Equinox Turning Over but Not Starting
Several factors can cause your Chevy Equinox to crank but fail to start. Below are the most common culprits:
- Fuel Delivery Issues: If the fuel pump is malfunctioning or the fuel filter is clogged, the engine may not be receiving the fuel it needs to start.
- Ignition System Problems: Faulty spark plugs, ignition coils, or a malfunctioning ignition control module can prevent the engine from igniting the air-fuel mixture.
- Battery or Electrical Issues: While the starter motor may turn the engine over, a weak battery or corroded connections can prevent sufficient power from reaching critical components like the fuel injectors or ignition system.
- Sensor Failures: Modern vehicles rely on sensors like the crankshaft position sensor or camshaft position sensor to provide data to the engine control unit (ECU). If these sensors fail, the ECU may not know when to fire the spark plugs or inject fuel.
- Empty or Contaminated Fuel Tank: It’s always worth checking if the fuel tank is empty or if the fuel is contaminated with water or debris.
- Security System Malfunction: If the anti-theft system is engaged or malfunctioning, it may prevent the engine from starting even though it cranks.
Understanding these potential causes can help narrow down the issue and guide you toward a solution.
Steps to Diagnose the Problem
To identify why your Chevy Equinox is turning over but not starting, follow these steps:
- Check the Fuel System: Listen for the fuel pump priming sound when you turn the key to the "on" position. If you don’t hear it, the fuel pump may be faulty. Also, inspect the fuel filter for clogs.
- Inspect the Ignition System: Remove a spark plug and check for wear or damage. Test for a spark by grounding the spark plug and cranking the engine.
- Test the Battery: Use a multimeter to check the battery voltage. A healthy battery should read around 12.6 volts when the engine is off.
- Scan for Error Codes: Use an OBD-II scanner to check for diagnostic trouble codes (DTCs) that may indicate sensor failures or other issues.
- Examine the Security System: Look for a flashing security light on the dashboard, which may indicate an issue with the anti-theft system.
By systematically diagnosing each component, you can pinpoint the root cause of the problem and take appropriate action.

Frequently Asked Questions
Why is my engine turning over but not starting?
The most common issues that would cause the engine to spin over but not start are the security system/ignition key problems that we spoke about, issues with the communication between the computers on the vehicle, and fuel pump/fuel system or engine compression/timing issues.
Why is there no sound when I turn the key in the ignition?
If you don't hear anything at all, it could be a problem with the ignition switch and fuse, the starter solenoid, or bad electrical systems in your car, to name a few. If you can hear a clicking noise, you may have a partially discharged battery or a damaged starter motor.
Why is my ignition not clicking over?
No clicking (or one single click) when you turn the key in your ignition points to an issue with your battery or your starter. Luckily, figuring out which component is to blame is pretty simple. Start by jumping your battery to see if that helps. If it doesn't—and your battery is corroded or old—replace the battery.
Why is my car turning over clicking but not starting?
Dead Battery
Cold cranking refers to when the car's battery doesn't have enough energy stored up in order to start the vehicle. If this is what's happening, then it will make a loud clicking noise each time you try and turn on your car but it won't actually start.
Why won't my Chevy Equinox start clicking?
If you try to start it and it just clicks that is most likely a problem with your starter, a loose connection on your battery, or a weak battery. First check the battery. It should have 12.5 volts +/-. While turning the ignition to the start position, check the small wire on the starter solenoid.
Why is my equinox turning over but not starting?
If the car cranks when you turn the key, but the engine won't start, it could be because fuel isn't getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
How much does it cost to replace a starter on a Chevy Equinox?
The average cost for a Chevrolet Equinox Starter Replacement is between $393 and $536. Labor costs are estimated between $104 and $131 while parts are priced between $290 and $405. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
Why is my car ticking over but not starting?
A rapid clicking sound might hint at a battery- or alternator-related issue. A single loud click might mean problems with your starter motor. Listen closely to the type of clicking you hear; you'll want to visit a certified mechanic, and give them specifics about the noises you're experiencing.
