how can i check if its a faulty ignition switch when the diy says" while its running" when it wont start at all

the check engine, oil lamp and park brake lights come on when i turn the key. if i wiggle the key it sometimes turns the heater fans on briefly. no cranking/clicking/whirling noises. battery is good. the temp just dropped into the -30s but never had problems starting before in cold. a few weeks prior to the "no start" i would start my car but the blower, and signal lights would not work occasionally. i eventually figured it out that if i turned the key back a few mm after starting it, the blower and blinkers would work

The ignition switch in a vehicle is responsible for sending a signal to the starter motor so that the engine will start. While the switch has no scheduled service life, in most vehicles it lasts quite a long time. If the switch fails, however, you won't be able to start your vehicle. But before replacing it, check to see if the ignition switch is in fact faulty.

Open the hood and set the dial on your voltmeter to "volts."

Touch the red lead of the voltmeter to the power terminal on the battery.

Touch the black lead on the voltmeter to the negative terminal on the battery.

Check the voltage output. The output should be 12.6 volts. If it is less than this, the battery is discharged. If the voltmeter reads anything below 12.3 volts, it is completely dead and needs to be replaced.

Pull down the fuse panel cover inside the cabin of your vehicle. Remove the fuse for the starter with the supplied fuse puller (in the fuse box). Check the metal strip inside the fuse to make sure it is not burnt or broken. If it is, replace the fuse with another fuse of the same amperage.

Once you've determined that the fuses are good, insert the key into the ignition and turn the key. If the vehicle won't start and you don't hear a "click" when you turn the ignition to the crank position, the ignition switch has failed and needs to be replaced.
