It is in a common circuit with something else. If you can find the listing of what the fuse circuits are, you might find which one it is. You also might trace the wires out and see where it is broken. The tach sensor has nothing to do with the fuel shut off. The fuel shut off is controlled by the key switch through the fuse box to the solenoid. I don't recall if it goes through a relay or not, and don't have a diagram in front of me to tell you. When I don't know which fuse it is, I usually test them one at a time and find the guilty one that way. Then it gets marked as to what it protects
