is this a bad ecu?

k iv got a 91 civic si with mpfi swap, so i got a code 9 , so i used the trouble shooting thing for ecu codes.. says to check the distirbutor for ohms of resistance.. its within the allowed number then it says check for continuity. so i did, and one wire has continuity the other doesnt(the wires im talking about are the two blue ones that is only on the is dizzy) so i disconected the wires from the dizzy, checked all the stuff and it was good on the dizzy , then i checked for continuity on the wires going to the ecu and only the one wire has continuity. so i tried unplugging the Aplug from the ecu and tested the wires again, and the wire didnt have continuity anymore .. whats going on? is there a short somewhere in my wires????
