84 190D ignition cylinder problem?

[patryk]

Hello, i just bought a 190D and i was wondering if maybe i have bad ignition key cylinder problem. I've had the car for about 3 days and i took it to work today...i work at a shop.. and i put it on my lift. Upon completing an inspection on it i go to start the vehile and nothing... no crank. Feels like kind of the ignition key cylinder is not letter me turn all the way to the start position... i can get it to run and everything else. The key is not stuck in the ignition and it comes out every time. I had to jump the solenoid on my starter to get it running back from work. The vehicle was fine for the first three days...had no problem starting it. I was wondering what parts i would need and the procedure for removing and installing these parts. Thanks.
