Removing and bypassing the fuel pump relay (connecting socket 30 to 87
as shown in Bentley) might be needed, but wouldn't the hall signal
pulse the fuel pump? I've never done this test.

You obviously know this but for anyone else, be sure not to turn turn
the engine with dizzy up and away from the drive gear.

For removing injectors for spray test, I'd apply penetrating fluid to
each 10mm head bolt on each fuel injector hold down bracket. A medium
rap with a hammer couldn't hurt. Beware of Corrosion and Time...   ;)

With each bolt off, each pair of injectors comes away the intake
manifold. At the very least, replace the O-rings at tip of each
injector. The larger O-rings might be ok but if they look old, I'd
replace them but this may take you into fuel line replacement time.
