1999 Subaru Legacy Sedan..
I finally fixed mine, on my 1999 Subaru legacy 30th anniv edition. . .
I removed the speedometer head, and resoldered the green connector on the board. Then I also ran a wire to duplicate the trace wire from the middle pin to the first connect (about 4mm). Problem gone.

How do i ck if fuel pump defective or no pulse at injector no power.
If you have fuel coming out of the lines when you are cranking the engine then your fuel pump is working. You should only get a small burst of fuel when you first turn the key on and then nothing while the key is on, the ECU only tells the fuel pump to turn on when cranking and when it can see cam and crank sensor signals while the engine is running. The small burst of fuel you may or may not have experienced is only to prime the fuel rails. To test your injectors, you can buy what is called a "noid" light. They have them at most stores that have a good tool/automotive section, such as sears. You unplug one injector with the engine off, plug the noid light into the injector connector (harness side going to injector). Then start or crank the engine over and see if you can see the light pulse on and of very fast. You may need two people due to limited visibility while cranking the engine. Repeat this for the rest of the injectors. If you have an "ohm" meter, you can ohm check the injectors by disconnecting each one and touching the pins inside the connector cavity on each injector. The ohm reading should read between 5-20 ohms. I hope this info helps!

WHAT WOULD CAUSE NO INJECTOR PULSE 1999 SUB 2.2L LEGACY L
Seems as though you have a wiring problem if your injectors have no ground.
I suggest you check the wiring diagram to see how the injectors are grounded. If they are grounded by a common point on engine or chassis repairing or duplicating it should be straightforward but more complicated if both the injector pulse and the ground are provided by the ECU.
