Default 91 si conversion dx cuts out at 3000!!!! help

The dx wiring was shorted somewhere so I switched the inner and outer harness with one from an si. Car starts but I cant find the plug for the fast idle and I also am not getting any power to the fuel pump. I jumped it to get it running but at partial throttle it wont rev over like 3k. Ideas? already tried ignition and cam timing.
