Ok, we are going to need to check for power to and out of the ignition switch. You will need a voltmeter and I need to know if yours has the ignition in the steering column or on the dash
Ok, at the ignition switch you should have a large white with red striped wire. Check for 12v on it. This sends power to the switch. If no power, we will need to back trace that wire. IF 12v is present, then check for 12v on the black with blue striped wire with key in cranking position and 12v on the black with orange wire with key in on position
If power missing from either of these, replace the switch.
You will need to remove the lower trim pads below the steering column and steering column covers to reach the switch, which is connected to the ignition cylinder that the key goes into
Ok, sounds good.
