Many drivers experience the disheartening situation of their car having power but refusing to crank.

This issue can stem from various sources, ranging from a faulty starter to a problematic ignition system. Identifying the root cause is crucial for effective troubleshooting. Before panicking, take a deep breath and let’s systematically investigate the most common culprits. This guide will help you understand why your car has power but won’t crank and how to fix it.
Car Won't Crank But Dashboard Lights Are On
Common Causes and Solutions for a Car That Won’t Crank
One common culprit when your car has power but won’t crank is a dead or weak battery. While the car might have enough power to illuminate the dashboard, it might not have the necessary juice to power the starter motor. This is often accompanied by clicking sounds when you try to start the car.
Checking Your Car Battery
Testing the battery with a multimeter is the most accurate way to determine its health. A reading below 12.6 volts typically indicates a weak battery. If your battery is weak, try jump-starting your car. If the car starts, it’s a clear sign of a battery issue. 2020 chevy equinox key fob battery could also be a problem, especially if your key fob is not working properly.
What if the battery is fine but the car still won’t crank? The starter motor could be the problem. This component is responsible for cranking the engine, and a faulty starter can prevent the engine from turning over.
Inspecting the Starter Motor
A clicking sound when turning the key often indicates a bad starter. Tapping the starter motor lightly with a hammer or wrench can sometimes temporarily dislodge a stuck starter solenoid, allowing the engine to crank. However, this is just a temporary fix, and replacing the starter is the ultimate solution.
Other Potential Issues: Ignition System and More
Beyond the battery and starter, several other components can contribute to a car having power but not cranking. The ignition system, responsible for providing the spark that ignites the fuel, can malfunction and prevent the engine from starting.
Diagnosing Ignition System Problems
Problems with the ignition switch, ignition coil, or other ignition components can cause starting issues. A faulty ignition switch may not send the correct signal to the starter, while a failing ignition coil may not produce the necessary spark. Testing these components requires specialized tools and knowledge, and consulting a professional mechanic is often recommended. chevy equinox key fob battery replacement may also be needed if you find your key fob is not functioning as it should.
Another potential culprit is a faulty neutral safety switch. This switch prevents the car from starting unless the transmission is in park or neutral.
Checking the Neutral Safety Switch
If the car starts in neutral but not in park (or vice-versa), it might indicate a problem with the neutral safety switch. A mechanic can test the switch and replace it if necessary. A bad chevy equinox key fob battery can sometimes cause similar issues, so make sure to check that as well.
“A common oversight when diagnosing starting issues is overlooking the simple things, like corroded battery terminals,” says automotive expert, John Miller, ASE Certified Master Technician. “Cleaning these terminals can often resolve the problem quickly.”
