Why is my car not fully turning off?
If the engine continues to run just as before you turned it off - as if you hadn't turned it off at all - your ignition and fuel system are not shutting down. In that case, your car has an electrical problem that needs to be addressed. Either your ignition switch element or a power relay needs to be replaced.
If this only happens first thing in the morning, a weak battery or a drain in the electrical system are likely causes. (You could look for a stuck trunk or glove-box light, but other causes are less visible.) If the slow cranking occurs after driving (engine hot), it's likely a faulty starter or poor charging.
If your vehicle engine continues to run after the ignition switch is turned off that means the ignition switch is defective and/or the ignition is still being powered from "elsewhere" in the circuit even though the switch is "off".
The most common and obvious reason your car may start then die is the fuel shortage in your engine. This happens because there's not enough fuel in the fuel rail, and there's no fuel pressure to keep the engine alive. The reason isn't always you forgetting to fill up your gas tank.

In a car with a key ignition, turn the key to the off position and remove it from the ignition. In a car with push button ignition, press the start/stop button to stop the engine.
The primary culprits here are fouled spark plugs. Spark plug electrodes wear down over time, increasing the voltage needed to jump the gap in the plug and ignite the fuel and air mixture in the cylinder. That leads to longer cranking times before an engine fires up.

To turn off your car, make sure your car is in the parked gear, then press the engine start/stop button until the engine shuts off completely. You may also want to apply the parking brake.
A vehicle start-stop system or stop-start system automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions.
Spark plugs, themselves, can cost anywhere from $5 to $20, depending on the make and model of your car. Mechanics and auto shops will typically charge anywhere from $115 to $200 for a professional spark plug replacement.
Will my car start if the spark plugs are bad?
The Car Has Trouble Starting
If spark plugs have become clogged or worn down, the car's engine has to work overtime in order to make up for the overworked plugs. Sometimes the car will not start at all because there is simply not enough spark created to turn the engine over.
Ordinary copper and nickel spark plugs should be changed every 30,000 to 50,000 miles, unless otherwise suggested by the spark plug manufacturer. Platinum and iridium spark plugs tend to last longer than standard copper and nickel spark plugs. Expect to change them every 60,000 to 150,000 miles unless otherwise noted.
Slow cranking could be the result of several possible conditions, and as you've suggested, the fault might reappear or worsen. Possible causes are a degraded or defective battery, faulty electrical connection, a charging system problem, a bad starter or battery rundown when parked.
If the problem is the fuel filter, and it isn't changed soon, you may find that your vehicle won't start at all. Misfire or rough idle. A dirty fuel filter could prevent the engine from getting enough fuel. Vehicle stalling.
Slow Cranking: For the starter to be cranking, the control circuit would have to be working. So, if battery and cable checks are within specification and the vehicle still cranks slowly, then it's a slow cranking problem and it's time to replace the starter.

If the fuel pump fails completely — to the point of not being able to provide enough fuel for the engine to run, the vehicle will refuse to start. The engine will still crank when the key is turned, but it will be unable to start due to the lack of fuel.
LEAVING YOUR KEY CLOSE TO YOUR CAR
Leaving your car key in your car overnight or even on a hook near the car is not recommended. If the fob is too close to your car, it can continue to communicate with it, which could drain the battery.
Why Your Car Battery Keeps Dying. While car batteries slowly die over time, high heat, brutal cold, excessive use of vehicle accessories (after-market equipment), and other mechanical issues can shorten the life of even the toughest battery.
What drains a car battery overnight?
What may drain a car battery when it's off are things such as interior lights, door lights, or even bad relays. While your engine runs, the alternator recharges the battery — which is why you typically don't have to worry about the battery dying while you're blasting the radio on your drive to work!
- If your key is not giving out any signal.
- If you have to press the button repeatedly before your vehicle accepts the signal.
- If your key remote is inconsistent or unreliable.
Most modern fobs can send a signal to your vehicle from up to 50 feet away. As your battery wears out though, both the range and signal strength will be reduced. If you find yourself having to repeatedly push buttons to lock and unlock doors, that's another sign that your key fob battery needs to be replaced.
Your car stalls while driving
If the ignition switch fails while the engine is still on, it may cut off power to the ignition and fuel systems, which will cause the engine to stall. Depending on the exact issue, the vehicle may or may not be able to be restarted a short while later.
Usually, an ignition switch replacement will only take about 20 minutes. However, it could take much longer depending on your car's make and model and the complexity of the ignition covers. The best way to know for sure how long your service will take is to talk to the mechanic directly.
The average fuel pump lasts for more than 100,000 miles and sometimes longer, so more than likely, you won't have to worry about it failing for quite a while. But the more miles your car accumulates, the more liable you are to run into a failed fuel pump.
How long does it take to replace a fuel pump? In most cases, around two to three hours. However, job times can vary widely depending on how easy it is to access the pump.
With a fuel leak, a car is never safe to drive.
In addition, leaks in the fuel system are a common cause of car fires. Since gas is extremely combustible, it is possible that it may spark a fire, either inside the car or elsewhere, if it leaks. Therefore, fixing the leak as soon as possible is highly recommended.
Factors that can shorten its life include an extended period of partial or full discharge, vibration from not being properly secured, under- or overcharging, extreme temperatures, water loss, electrolyte contamination and corrosion on terminals.
A conventional car can last for 200,000 miles. Some well-maintained car models will reach 300,000 or more miles total. The average passenger car age is currently around 12 years in the United States. Choosing a well-built make and model can help extend your car's longevity.
How many times can you start a car before the battery dies?
An auto battery has a limited number of times it can start your vehicle before it needs to be replaced. Most car batteries will last between 500 and 1,000 charging cycles, which works out to a lifespan of between three and five years, depending on driving and weather conditions.
