When I turn my key I can feel no physical feedback and my car wont turn on or start

 

Sounds like either your ignition switch has broken, or the linkage is broken between the lock cylinder and the ignition switch.

 

OK what do i have to do to fix the linkage?

 

Well, you jumped right on the more complicated possibility. Why? Give us more detail on how you determined it wasn't an ignition switch. What have you done, what do you see? As for what you should see, you can do a Google search on your model year of GM ignition switch linkage and find a ton of pics and videos to help you know what it should look like. The good part is that these have been the same, or similar, over a couple of decades and almost all GM cars of the late 70's to mid-90's era. However, if it were me, I would start with checking the ignition switch. Is it still bolted on, is it loose, is the linkage still connected to it, does the linkage move when you turn the lock cylinder. That could save a lot of time. Otherwise you may have to pull the column apart to get access to the gear actuator part of the linkage.

 

Ok well I pulled the steering wheel off and lowered the steering column, when I turn the the cylinder lock back and forth I can see two metal pieces on the other side of the steering column move , the two metal rods that go down the steering column don't move at all when I turn the key but when I pull one of them back manually my accessories and fuel pump come on

 

Ok i think i found my problem the rounded end of this piece is completly broken off ,any idea how to replace it ?im kinda new to working on cars
