Bentley should show values for injector wire resistance (total and at
each plug IIRC). It should also show a voltage value at each injector
plug.

There is a method for checking fuel spray that's useful if you're
working on your own. If you search Mark Drillocks email address it
should come up in the archives here:

Basically, you lift the dist. up so it's dis-engaged from gear and
with ign. on, turn the rotor by hand while watching the removed
injectors. The hall in distributor should signal the ECU to cause the
injectors to spray. (this is a batch fire system; they should all
spray at once)

Here's a link to a large-ish pdf file of the Vanagon Digifant pro
training manual. If your Bentley is the latest edition, it may contain
same, but this is easy to download and print out and handy to carry in
the van:
