It sounds like you must have a break in the wiring after the EFI fuse. Once you jump the relay directly, pulling the fuses wouldn't do anything because they are no longer supplying the power, your jumper wire is.
Check for voltage at the + input for the relay's internal coil (normally an 85 or 86 if it's marked). If there is power, check the relay coil's ground wire for continuity with the chassis ground. One of those should fail, when it does start tracing that wire to find either the faulty switch/relay or break in the wire
