sounds like you have a bad ignition ground
Because you turned the key.
1994 Acura Legend Car cranks but when you let go the key it shut off?
what kind of car? IF its fuel injected the key turns off the computer, the fuel pump, and the ignition coil
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.
u can shut off a car while its in gear u just wont be able to get the key out without it being in park and the sterring wheel may lock but u can shut a car off with it in gear
It is normal for the emergency flashers to work with key on or off. You need to shut the e-flashers off with the e-flasher switch.
I don't know what kind of car you have but the heated seats in my Equinox shut off when the key is turned off.
Put the vehicle in neutral and shut it off. ---------- Make absolutely certain when you shut the car off that you don't rotate the key back too far or you will lock the steering wheel and be unable to steer the car. Just turn the key far enough to shut off the engine. Be careful. -------------- Just another thought... once you shut off the motor the car will be very difficult to steer and brake as the power steering and brake systems will be shut down.
turn the inside lights off
On a carburated vehicle the power to the distributor and coil is cut off when the key is turned off causing it not to fire.
the car alarm will allow the car to start and run briefly then "shut down".
sounds like you need a new ignition switch
