What is this fuse for?

[nismo13s]

can someone tell what this fuse is for. it is the second brown fuse from the left. one side of my injectors is getting power when the key is off and out of ign, when i pull this fuse the power goes away. most of the power goes away the light on the test light still has a tiny bit of power. i think if i can trace this wire for the fuse i can find my crank no start problem, thanksoh yea this is for a 90 240sx s13.[IMG][/IMG]
