Get AC power when on the first click but no warning lights or anything in the "on position". Can start the car and back the key off a bit to keep it running but as soon as I let the key click back to the on position it stops. Also can get dash lights when halfway between the AC and On position. Did this a couple of months back but came right 20 mins later, now it doesn't want to cooperate.
Does anyone know if the ignition switch can twist a bit and be slightly off the key positions? Because I can get power when halfway between the clicks.

Turn the key to the run position. Check the dash to see if the security light is flashing. If it is, leave the key in the on position till the light stops flashing. (this may take ten minutes) When the light stops flashing, turn the key to the off position. Then start the car. Make sure the head lights are turned off so that you do not kill the battery.
it may be a bad ignition switch=try this test! ( supplies about 50% of power. put key to position 2 the oil light, brake light, charge light and all other warning lights will not function.turn key to start position, as soon as it trys to start let go of key. allow to snap back to run position. and note warning lights, if warning lights go out when switch is snapped back! switch is faulty. in this case. there is no power past switch. check all of the main fuses first!! and wiring to rule them out.
Does anything work? Lights, radio? Do the warning lights and gauges turn on when key is turned to on? That would verify power is getting to the ignition switch and is being sent out. Pretty limited in what you can check without a voltmeter or test light. If you have power to the ignition switch, need to know if power is getting to the starter solenoid on the starter motor when the key is held in cranking position. If power there, likely a new starter is called for-have yours tested.
Do you notice anything unusual with the dash lights when you turn the key on. All the warning lights should illuminate. If they do not but then come on as you start to rotate the key into the start position than you probably have a bad ignition switch.
If you turn the key to the start position and hold it there (only do this for a few seconds) will the car stay running until you let go of the key? Another clue that the ignition switch may be bad.
if you turn the key to the start position and the vehicle starts slowly let the key rotate back to the run position until the starter disengages. If the vehicle continues to run let go of the key. If the vehicle stalls than the ignition switch is definitely bad.
In older cars, the natural wear and tear on a vehicle can lead to ignition switch failure. If the switch is failing, you will probably not hear any clicks from the main relay, which fires the ignition. Check the behavior of the dashboard lights if your vehicle stalls. Alternatively, when the key is first turned to position two, the oil light, brake light, charge light and other warning lights will not function. You can try a test to check the integrity of the ignition switch by turning the ignition key to the 'start' position. As soon as it tries to start let go of the key. Allow it to snap back to the 'run' position and note warning lights. If they go out as the switch snaps back then the switch is faulty. if faulty it will not let power through to the starter to start car. check all fuses first. but sounds like switch.
The security light being on is why your vehicle will not start.You need to get the codes to find out what is causing the problem.What you can do is when you try to start it and let go of the key but leave it to the run position the security light will come on and stay on for ten minutes.When it goes off turn the key off and then try to start it.The theft module relearns the key and it should start.Then you can take it to a repair shop and get it fixed.You can call ahead and make sure there is a shop that can diagnose and repair this problem.Hope this helps.Good luck.
