Okay so I have a 92 cx hatch with a swapped D16Z6 in it. I got home about twenty minutes ago and went to shut off my car.. it didnt shut off.

Breaking it down
Took key out - motor stayed on, radio turned off
Put key back in - motor still on, radio turned back on, dinging noise came on like when you turn the key (normal)
Took key out again - motor stayed on, radio turned off, car idled higher
Put key in and stalled the car on purpose - motor turns off, dash lights go nuts.

I have a video of what happens when i start it now and shut it off.

Bad ignition switch perhaps?

Need more people to chime in.

 

I did lose my keys last week and have been using a badly cut copy so i have to shake it a little bit to get it to start.. can that hurt the ignition?

 

dont worry about the copied key, i think is the electrical part of your swtichit goes from the back of the cylinder key to the fuses box, i bet you its burn inside!!!

 

alright ill give it a looksee in a few minutes.

 

my 96' hatch did this one time.. i have no idea why, but the then the motor died and it would start back up, i left it alone and like an hour later it worked fine. sorry i cant help you out any, but bump for the cause.

 

well i took it for a drive and it hasnt done it for a while.. im gonna go check all the wires and make sure none are shorting out tomorrow.
