    Hey all, same 91 Sub, it has a weird problem that if the shifter goes too far forward toward the engine, the motor will kill. It is importnat to note that it looks like the shifter is going too far forward when this problem causes the motor to kill. I'm guessing there's some sort of backstop that's broken in the column, but I'm not sure. The previous owner made a temporary fix to the problem by attaching several rubber bands to the shifter and the non-turning section of the ignition cylinder, thereby keeping it from going too far forward. He told me that a friend of his looked at it and guessed it was possibly 3 diffrent parts, all of which have something to do with the horn.. Now, this doesn't sound right, but I don't think it's going to be anything terribly difficult to fix. Unfortunatley, like all my other posts so far, I can't run out to the truck to give exact details as I haven't take delivery with it yet, but I have a pretty good photographic memory, especially about these few problems the truck has. Thanks

    Check the neutral safety switch

    I would look at the neutral safety switch. It is connected to the shifter and might be the source of your trouble. It is near the base of the steering column if my memory serves me correctly. It looks like this:

    killing engine

    What he said.

    Could just be loose, or defective.

    I don't want to be the one to disagree, and I'm not saying that I do. But the neutral safety switch is at the base of the steering column at the wall. Maybe I'm misunderstanding what he's saying, but it sounds like the selector arm itself is causing the problem, like it's shorting out on something closer to the arm itself.

    or...

    When you turn the key to start the engine, doesn't that control linkage, that operates the ignition switch? I've never actually pulled one of these columns apart before. If the arm has more travel than it's originally allowed to have, is it possible that it's making contact with that linkage, and pushing it back into an off position?

    trailleadr, are you always right??? ;) You sound like you hit the nail on the head with the problem. My uncle came up with a similar scenario with the whole ignition rod-thing causing the motor to turn off. Unfortunatley, until I take delivery and get a chance to pull the column apart, I don't know for sure.

    It could be anything related to the switch, ignition, neutral safety.

    I have had to change entire columns because of similar problems.

    Worst case scenario pull the column and replace with a bone yard one.

    You won’t know for sure until you get the thing apart.

    Good luck and if you need us we will be here.

    Yeah, that's probably not a good thing. But I promise to stay grounded in reality.:biggrin:
