Question about 1999 Nissan Altima
Trying to narrow down which circut sends electricity to fuel injectors.
Dear cindy: Your injectors are served from the fuse block by a 10A fuse. This is a brown and red wire which goes directly to the injectors and is hot all the time. The ECM makes and breaks the ground to pulse the injectors.
Coming off the ECM, are four wires which are numbered as followed. pin #102 (#1 inj) red and black, pin #107 (#2 inj) yellow and black, pin #104 (#3 inj) green and black and pin #09 (#4 inj)blue and black. These all pulse the grounds and are triggered by the ignition pulse. I hope this has shed some light on the subject.
Often you can go to a Barnes and Noble book store and find shop manuals which will give you the diagrams you seek. You don't necessarily need to buy the book if you are seeking a specific answer. Good Luck.
