If it's the crank angle sensor it shouldn't be too costly.
I replaced the crank angle sensor on my 940GLE at about 230,000km it only
cost about $120 Australian for the part, about the same as a friend spent on
a replacement 940 wheel trim.  Sometimes with volvo, non essentials are
costly and other important parts are pretty good.
Hope you find what you are looking for at a good price.

Not sure what the problem is but there is such a thing on later 240s
called the crank or flywheel angle sensor. I had mine replaced on my
'93 by my mechanic when the car would sometimes start and sometimes
not. Excluding the towing charge, the part and labor weren't bad.

I understand this sensor is at the back of the engine near the top of
the bell housing but I've never done the work myself.
