ok so I 've got a 98 legacy 2.2L going into a 92 loyale.  It cranks, the fuel pump primes,  won't start,  (haven't checked spark yet)  here is the thing I'm stuck on there is a wire shown on the front page of the legacy wiring diagram that starts at (ST ig sw)  runs to starter interlock, N. Pos. S/W, ecu pins 82 ,75, 17, and 18.  then it finally goes through engine wiring harness to an indirect ground (whatever that means.)  so I didn't like the idea of having starter circuit voltage going through the computer. I put in a fuse and its constantly blowing during cranking.  I wired it into one of the two ignition sw wires that is hot only during cranking (st position) My first thought is why is a starter voltage carying wire running through the computer and straight to ground with no load ( explains blown fuses ).  Any ideas I'm completely stumped.   
thanks
