I was driving my beloved 91 previa with 338,000 miles on it today. I
drove about 2 miles and it died, which was odd. I drove another mile
and it died. I did this several times until it wouldnt even turn over.
No lights came on. I heard no noises. It didnt overheat. The engine
wont turn. The shaft that runs forward that drives the ac etc will not
budge, but the alternator pulleys will move. Is there anything left
except internal engine problems that arent worth fixing on this old
vehicle?

When you say that the separated accessory drive shaft (SADS) will not budge,
did you put a wrench the front and try turning it by hand? For safety
reasons, disconnect the battery before you do this. If you can turn the
SADS and engine, the starter may be bad.

If you can't turn the SADS from under the hood, try this: The SADS is
connected to the front of the engine with 4 bolts. With a marker or dabs of
paint, mark the bolts and holes so that the shaft, bolts, and holes go back
exactly the same way, support the shaft with some wire or string so it
doesn't dangle down, and disconnect the SADS from the engine and see if you
can turn the SADS exactly 360 degrees. You are looking to see if the SADS
is binding or the engine is binding. If the SADS rotates, try turning the
engine over by hand by putting a wrench on the crankshaft bolt. If the
engine won't turn over, you will have to drop the oil pan to see if there
are metal particles in the pan.
