most likely your ignition switch is bad. is not breaking the circuit.
Or your vehicale is running so rich (air to fuel ratio) that the catalitic converter is glowing red hot from working so hard to burn up the unburned fuel. So in theory even though you turn off the ignition which usually kills power to the coils ( the source of ignition) your car will continue to run because now the source of ignition is taking over by the red hot cats. This is most common on carbed vehicales, because fuel injected vehicales supply of gas along with ignition is killed when the ignition is switched off.
Yes, it just depends on which fuse.
If your car uses VVT(Variable Valve Timing) or adjusts its ignition timing it could cause poor fuel economy, misfires, keep the car from starting. If the car is fuel injected the timing of the injectors is tied in with that too. In short nothing could, if the car manages to keep running it could lead to a blown motor depending on how you drive.
More than likely it does. Most (if not all) modern cars have a shock sensitive switch to cut off the fuel supply in case of an accident. Check the owner's manual. It is probably on the firewall behind a trim piece. It will have a reset button to turn the fuel system back on.
A car consumes fuel when it is running.
yes
Everything will shut down and the car will stop running.
It will ruin the engine and make it stop that way Depending on the car it may just make the car shut off
keep it running for short times
Well basicly, Turn the car off automaticly
Defective fuel pump, or clogged fuel filter is one cause.
sounds like you need a new ignition switch
Bad fuel pump.
Done properly there is nothing wrong with a cut and shut car but the seller should inform the buyer of the vehicle's history.
A malfunctioning the ignition switch will allow the car to keep running after the key is turned off. You can remove the positive ground cable from the battery to shut the car off.
You did not specify make model and year. If you have a very old car It could be doing what is called dieseling. OR The engine computer could be keeping it running to try to get it to cool off. But with out knowing what car it is those are just guesses.
There are some unknowns here. 1. Did you shut it off and it made a noise, OR 2. Did the car stop running suddenly, making a noise? If you shut the car off, some quiet noises are normal. You may hear the fuel pump from the rear of the car for a couple seconds, and you may hear a solenoid under the hood for a second or two, or the electric radiator fan after the car is shut off. The other question is what kind of noise was it? A loud bang? A whoosh noise, a scrape noise? Did the engine seem to try and keep running? Please add more detail and I'll try to help.
You don't unless you are parked with the engine running. If you are parked and you want the engine running but don't want the daytime running lights on just shut the car off and set the parking brake then start the car back up. The lights should remain off until you release the parking brake.
