1bad91s13

I just finished putting a red top sr in my 91 s13. The good it starts and runs fine. The bad I have to just the fuel pump at the relay to get the pump to come on. I checked for continuity from the relay on the black/pink wire all the way to the ecu and there are no breaks in the wire. But the ecu isn't supplying the ground signal to trigger the relay.
Also my tach doesn't work. I tested the yellow/red wire with a multi tester and it too has continuity but no tach. The wire also shows 6 volts with key on and 6 volts with engine running.
I'm guessing its my ecu but am hopeing for something else as redtop ecus are falling off trees here.
Any help would be greatly appriciated.
**also this was an auto ka to manual sr swap don't know if that matters.
