Car Won't Turn Over But Has Power? Here's What To Do
It's a common problem - you go to turn over your car but nothing happens. You know the battery has power, but the car just won't start. Commonly referred to as "cranking", this issue is often caused by a number of different factors. In this article, we'll take a look at some of the most common reasons why your car won't turn over but has power, and what you can do to get it back on the road.
Check The Battery
The first thing to check if your car won't turn over but has power is the battery. Make sure it is charged, as a low or dead battery can cause the car not to start. You can check the battery's charge with a voltmeter, and you can also check for any visible signs of damage. If the battery appears to be in good condition, then move on to the next step.
Check The Starter Motor
The starter motor is responsible for turning over the engine when the key is turned. If the starter motor is not functioning correctly, then the car will not start. To check the starter motor, first make sure the battery is in good condition. If the battery is good, then use a multimeter to check for any voltage drops in the starter motor. If there are any, then the starter motor may need to be replaced.
Check The Ignition System
If the battery and starter motor are in good condition, then it's time to check the ignition system. This includes the spark plugs, spark plug wires, distributor cap, and ignition coil. These components are responsible for creating a spark that ignites the fuel in the engine. If any of these components are faulty or not functioning correctly, then the car will not start. Check each component for any visible signs of damage, and if necessary, replace them.
Check The Fuel System
The fuel system is responsible for delivering fuel to the engine. If there is not enough fuel getting to the engine, it will not start. Check the fuel filter, fuel pump, and fuel injectors for any signs of damage or blockage. If any of these components are not functioning correctly, then they will need to be replaced in order to get the car running again.
Check The Computer System
The computer system is responsible for controlling many of the car's functions, such as the fuel injection system and the ignition system. If there is a fault in the computer system, then the car may not start. To check the computer system, use a diagnostic scanner to read the codes. If any codes appear, then the computer system may need to be replaced.
Check The Alternator
The alternator is responsible for keeping the battery charged while the engine is running. If the alternator is not functioning correctly, then the battery will not be able to keep the car running. To check the alternator, use a voltmeter to check the voltage output. If the voltage is low, then the alternator may need to be replaced.
Check The Belts And Hoses
The belts and hoses are responsible for keeping the engine running smoothly. If any of these components are worn or damaged, then the engine will not be able to turn over. Check each belt and hose for any signs of wear or damage, and if necessary, replace them.
Check The Wiring Harness
The wiring harness is responsible for connecting all of the car's electrical components. If there is a fault in the wiring harness, then the car may not start. To check the wiring harness, use a multimeter to check for any shorts or breaks in the wiring. If any are found, then the wiring harness may need to be replaced.
Conclusion
If your car won't turn over but has power, then there are a number of different things that could be causing the issue. Check the battery, starter motor, ignition system, fuel system, computer system, alternator, belts and hoses, and wiring harness for any signs of damage or wear. If any of these components are not functioning correctly, then they will need to be replaced in order to get the car running again.
