    Default 1989 C1500 Ignition Tumbler Stuck.

    I have a 1989 C1500 2wd 5.7. Today I tried to start the truck but the key would only turn the first click then it would get stuck and would not crank. No matter how much you try to force the key will not turn over. I replaced the ignition tumbler to see if this was the problem but it didnt not change a thing. Has anyone else had this problem?? Any Help?

    Sounds like you have a mechanical problem inside the electrical portion of the ignition switch mounted on the side of the column.
    Or there is a mechanical problem with the linkage between the key tumbler assy and the electrical switch.

    Either way it soulds like you are going to have to partly disassemble the steering column to see what's going on.
