13B-T glow plugs or not?

Nice! It is safe to drive it, it’s only purpose is to shut off the engine. Probabaly just need to buy a new VSV switch. You can either stall it in 5th gear to shutoff, or open the hood and pull the fuel cutoff.

13BT died while driving

You were spot-on! I was in Aussie for a week while the LC was in the garage in New Zealand for repair. When I came back home, the fault hadn't been found and I was advised to tow the LC to a diesel specialist in the 'big city'. But instead I followed your advise, pulled that tube off, turned the ignition et voilà, the engine kept running until I reconnected that tube again. No need for towing! I'll have a look tomorrow to see if I can find what causes the vacuum to be permanently on. In the meantime, is it safe to drive the truck with this tube disconnected? If it's indeed the low oil pressure shut-off, it might not be a good idea to drive it at all, but I had the pressure sender replaced not so long ago because the gauge on the dash board showed a bit low.

Thanks,

And here comes the embarrassing part: The oil was low! Not safe to keep driving therefore! Well done Toyota for this goofy thing on the 13b-t engine. I started the engine with the vacuum tube off, found a level spot (I haven't at home except inside), stopped the engine by reconnecting the vacuum tube, checked and topped up the oil and started the engine with the vacuum tube on and it ran as before. Thanks to all who contributed to answering my question. Thanks very much!

Nice. I feel like I’ve earned an “I told you so” ribbon.
That silly vacuum shut off has stumped a lot of mechanics. It’s one of those things that is unique to the 13B-T, and if you don’t know about it, then you just don’t know about it.
