    Hi all,

    Recently I was driving to school and my truck just shut off. No studder or anything. Just a clean cut-off. Today, I was driving to work and I made a left hand turn and it just shut off again. Any idea's ? I drive an '85 fullsize Blazer with a stock carbed 350. Thanks,

    Nick

    Couple of things... Do you have tilt wheel?? If so both times it shut off were you in a turn? If so then the u-joint in the tilt could be worn causing the rod between the key lock cylinder to move and thus turning off the ignition.. or is the truck up to normal temp when this happens? If so will it re-start after a bit? If so then the coil is shutting down once it gets hot..
    Hope this helps /forums/images/graemlins/thumb.gif

    I read something here, what is it? "Try and be more vague, I'm practicing my mindreading skills."
    You need to provide the readers with more information if you want help. What, radio also quits? Lights go out? You turning the steering wheel? Are you at a standstill? On a hill? Just to up and die sounds like an electricial failure.
    No shuddering or jerking?

    If I had any of those problems, I would have mentioned them. Don't have a radio so that's not a problem. Did it once when I turned the wheel but the rest of the time I will be stopped GOING STRAIGHT and it dies. No shuddering. Just cuts out.

    I had a same problem few months ago. It turned out to be the ignition switch.

    Maybe just have the truck running, and move around the truck grabbing wires and moving them.

    If it's an intermittent problem like that, sounds like a bad connection somewhere more than anything.

    Ever had an alarm in the vehicle? Make sure the ignition wire, etc., hasn't been tampered with, and check all splices that aren't factory, as usually they are poorly done, and can cause these type of problems.

    Had a car once that had a poorly spliced coil wire. Ended up leaving it at a friends house one time because it wouldn't start.

    What about the possibility of the fuel pump or fuel filter ? It has stuttered at one time but it did not result in the truck dying.

    If it is the pump or filter, next time it dies, without trying to restart it it, get out, pull the air cleaner off, look down the primaries of the carb, and move the throttle linkage. If you see fuel squirt out, its not a fuel delivery problem.
