Ign. on, each FI plug should have a constant B+ on one side. There is
a B+ junction in the black junction box. IIRC, this supplies B+ to
FI's. The test should be shown in Bentley for this. Also, check
continuity between each FI plug negative wire and ECU plug. The FI's
are activated by a supplied negative ground from the ECU. I see this
as ECU 12.

I find it hard to believe that 3 injectors are faulty. But as you say,
the engine has sat some time unused.

Is the known good injector spraying each and every time?
