Hi Bill,
    It appears your injectors are on solid. The relay next to the one you
mention for the fuel pump supplies 12v battery power  to most all the fuel
injection system including one  side of  the fi (fuel injectors). The ecu
(digijet in your case) provides a pulsed ground return to the other side of
the injectors. You could have a defective ecu, or have a short to ground in
the fuel injector cable or even a shorted injector (one shorted injector can
cause all 4 to fail on) .
    I would unplug all the injectors and plug a spare injector  into the fi
cable.  Then  do some voltage  checking of the injector plugs (they are all
in parallel at the ecu). If you don't have a spare injector disable the fuel
pump unplug all but one.  You should see about 12 volts on both connectors
of the fi plugs.
    Good luck with your quest.
Darrell
