Maintenance/Repairs

Car had been running fine and all the sudden turn the key and get nothing. Dash lights come on and there’s a click in glove box but nothing from starter. I have 0V at ignition post on solenoid with key in start position. I can short the 12V post and ignition post with screwdriver on solenoid and starter and engine crank as normal but car won’t start. Further checking I have 0V key off at ignition module, 12V with key on. A connector outside firewall between ignition switch and transmission neutral safety switch. I took this apart, it was a 7 pin with 2 of 7 blank. The red wire I had 0V key off, 12V key on. Then I dug into the steering column area. 12" or so down from the key there is a connector with a rod coming from the key area down into it. I assume this to be the ignition switch. The rod is supposed to move and is attached to a plunger that pushes into the connector. I assume this rod is attached to the key. When I turn the key the rod never moves. So I thought ok clamp some pliers on the rod and push it into the connector manually, it should make connection and start the car. When this had no results I am now at a loss as to where to go next. Further thought, how did I get the 12V readings in several locations with key on if ignition switch appears to be faulty. I’m not sure if it’s faulty or not, things don’t add up. I didn’t dig into the steering column where the key is yet because I will have to remove airbag and steering wheel to do so. I’m trying to troubleshoot around that first. If anyone can help me gain some understanding here I would be grateful to say the least. Thanks
