Question about 1999 Subaru Legacy
Fuel out of filter when cranking no flow with key on.
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!

try you map sensor or your throtle pos sens. your fuel pump is designed to run all the time. it is suppose to run through the fuel rail and back to the tank in a constant cycle.

Hi and welcome to FixYa,
To my understanding, there are two (2) ignition relays; 1 with 4 pins (B157 in the Relay Block) and the 2nd with six pins B47.
The 2nd relay is responsible for the injector +12 supply through the yellow/blue wire. Its is supplied through a black/red wire coming from a 30 Amps fuse in the Main Fuse box.
Good luck and thank you for asking FixYa.

check your grounds. I find many easy fixes by cleaning all the grounds around the engine bay. I would also check the ground at the fuel pump connector that wiring is prone to corrosion and breakage
