It depends largely on what vehicle, what transmission, and what, exactly the ignition malfunction is. If the ignition switch malfunctions in such a way that the 'On' position doesn't function, there's really not much you can do besides replacing the switch and starting the engine as normal; Not a very common situation, but it can happen.
For vehicles with automatic transmissions, you're pretty much stuck with one option (besides fixing the switch); You have to physically make the connection between two of the electrical terminals on the starter solenoid by either installing your own switch, or using a screwdriver (or similar object) to jump the terminals until the engine starts (Don't forget, the ignition must be in the 'ON' position, or the engine still won't start). It should go without saying that this presents something of a safety risk, so if you don't know what you're doing, don't do it, or have someone who knows how show you.
For vehicles with manual transmissions, you have the above option, plus the vehicle can be push started. Just turn the ignition on, put the transmission in 2nd or 3rd gear with the clutch pedal pressed to the floor, get the vehicle moving (hopefully you're on a hill or you have strong friends or a tow/pushing vehicle), then 'pop' the clutch up for a second to let the vehicle motion turn the engine over, but press the clutch back to the floor quickly before the engine stalls from mismatched engine/transmission/road speeds. It may take more than one attempt to get it right, and please be careful while attempting this.
Yes, a bad coil will prevent the ignition from firing and the engine will not start.
You don't. The ignition is required to start the car. If it fails you need a new ignition switch.
no..if its bad your car wont start
Ignition or ignition switch could be bad or the selanoid could have went out
Numerouse possibiities, bad gas, bad carburetor, bad spark plugs, bad spark plug wires, bad ignition coil, bad battery, bad ignition swithc, etc..
Usually vehicle just stops running with no warning
If you car won't start your battery may have dead. Try having your car jump started, if that does nit work, your starter may be bad.
There are many causes for a car not to start. One of the causes can be the fuel pump which pumps fuel into the carburetter to spray into the ignition chamber.A bad pump may not pump the fuel into the carburetter .
Start the car
ignition
The first problem was a bad ignition switch. There is a possibility that something in the key circuit has gotten bad enough that it is preventing the car from starting at all. There are a couple of connections shared between the remote start and the key start.
