Car won’t turn over

My car won't start today. When I put in the key and turn it nothing happens. It doesn't crank. The headlights and gauges worked. I've looked at my ignition fuse and it’s good. This never happened before. I can't figure this out. Do you have any ideas? What should I do?
Experienced mechanics share their insights in answering this question :
Hello there, a no-start condition is a very common fault. The most likely causes for this to happen on your 1999 Plymouth Breeze would be a battery, starter, battery cable, ignition switch, wiring harness fault, or an open circuit. Have a qualified technician, such as one from YourMechanic, diagnose the no-start condition and determine what repairs are necessary.

The three main reasons why an ignition key will not turn include: problems with related components, issues with the key itself, and ignition lock cylinder problems. Tip: Always make sure your parking brake is on to keep the vehicle secure when following these steps.
Why won`t my car start but I have power? If you attempt to start up your car but the engine won`t turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
Blown Fuse

If there has been a surge, a fuse that controls the fuel pump, the fuel injectors, or another component that`s vital for your car`s functioning, it may be the cause of your car`s failure to start. Unlike most of the other problems, this is one that you can check yourself, if you want.

Dead Battery

To work correctly, the ignition mechanism is powered by the battery. If the battery fails, the ignition will automatically get locked up. Then you won`t be able to pull the key out of the ignition.

The starter solenoid is an electromagnetic switch that engages the starter motor. How can I tell if my starter solenoid is bad? If you`re having trouble cranking the engine over but the battery is charged, or if your starter won`t disengage after starting the engine, it`s likely a starter solenoid issue.
Hard start symptoms and starter failure may NOT be caused by the starter, but could actually be caused by the crankshaft position sensor. If your vehicle is experiencing one or more of these symptoms, the crankshaft sensor may be at fault.
A Bad Crankshaft Position Sensor

The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.

The ignition relay is one of the most important electronic relays found on modern vehicles. It is usually located in the fuse and relay panel beneath the hood, and is responsible for providing power to the vehicle`s ignition system, and some of the fuel system`s components.
Turning your key turns your battery on, so if you`ve turned your key all the way and the lights come on, but the engine doesn`t turn over, your starter motor could be the culprit.
Insert your ignition key and turn it to Accessory (or press the start button once without pushing the brake pedal). Press the Lock button on your remote car starter. Within five seconds of turning it on, turn your key back to the “off” position (or press the start button again).
Unfortunately, if the starter motor has completely gone there`s no way to get your car going again. However, when a vehicle doesn`t start, it`s typically to do with the battery`s insufficient voltage to start the motor.
Starter motors should make noise when you turn your ignition key fully to activate your car. If you turn the key and do not hear anything, there`s a chance that there`s something wrong with the vehicle`s ignition switch.
The O2 sensor will not cause the no start. The no start can be caused by the fuel pump or the ignition system. You should check the engine for spark and fuel pressure, when it is not turning on to help narrow the problem down. The ignition system may be the coil, module, or pick up in the distributor.

As I’m driving, all my lights inside/out of the car turn off and the car still stays on. But when I turn the car off it won’t turn over
ANSWER : Hello there. The charging system on the car may not be charging the battery as you drive and the systems that keep the engine running are priority so the engine will stay running until the voltage drops below about 9 volts but the lighting and some other accessories may cut off above this voltage first. You should have the charging system tested to see if the alternator needs to be replaced.

Engine turned off but inside of car still on, now engine won’t turn back on.
ANSWER : Hi there. The symptoms you’re describing with your boyfriend’s 2002 Grand Cherokee appear to be related to a broken or worn out ignition switch or relay. The ignition switch on the inside of the steering column is attached to multiple electronic connections that send signals to a relay box; which in turn, sends the signal to the individual components. The issue could be related to the ignition switch, the relay, or any of the components in between. If you want to have the fault pinpointed in person, I would have this starting issue inspected by a trained professional to ensure that the correct repair is made.

car won’t start.
ANSWER : A possibility is a faulty ignition switch. If the switch opens after the car starts, the engine will shut off. But, that is just a possibility and a diagnostic would have to be performed to rule that in or out. Be sure you have a fully charged battery that passes a load test. Starters motors can display intermittent operation if they are faulty. With a fully charged battery, if the starter motor does not run that signifies an electrical problem in the starter circuit (includes the ignition switch) or a problem with the starter motor itself. If there is power to the starter motor and yet it doesn’t run, the starter is condemned and replaced. Alternatively, if there is no power to the starter, or there is a big voltage drop anywhere on the circuit to the starter, then the circuit has to be traced until the fault in the circuit is found. Notably, faults can include high resistances, due to corrosion, wire strand breaks, or loose terminals, which can only be diagnosed using a voltage drop test. Regardless of what the underlying cause of the no start condition is, if you desire that a certified mechanic resolve this promptly, please simply request a no start diagnostic and the responding mechanic will get it diagnosed and repaired for you. Please let us know if you have further concerns or questions as we are always here to help you.

ANSWER : The steering lock may not be unlocking either due to a faulty ignition lock housing or more commonly as the cars age a faulty spring at the steering wheel on the under side of the column. If the ignition lock housing is the issue the housing can be replaced. It s a bit tricky as the mounting bolt has break off heads and generally need to be driven out with a punch. If the lock is not disengaging because of a faulty spring on the ignition lock many owners have had the spring removed by having it drilled out of the housing. However, removing the spring may permanently disable the steering lock. The last option would be to replace the steering column. You may want to enlist the help of a mechanic who can recommend the proper repair for your situation.

ANSWER : If your vehicle was not starting but was turning over, I would have advised against the starter replacement. If the engine will turn over, the starter is doing its job. If you have an aftermarket security system on your vehicle, are unable to start your car, and are unable to lock and unlock the doors, I would recommend having the aftermarket security system inspected. The best place to have this done would be the place that it was originally installed as they would have the best knowledge of the system. This could be related to wiring, control modules, or other related components. Once the security system has been inspected, the repair procedure will be more clear.
