I'm a little confused by the story, but I can try to help...
When cold, the cold start injector time switch should read close to 0 ohms.
Did you cover up the hole in the manifold when you took out the cold start injector?
When starting the engine, the cold start injector should spray fuel for a few seconds to a few minutes, depending on engine temperature - did any fuel come out?
Its probably the cold start injector time switch that is the problem, though that often causes hard starting (though decent running once started and perfect after warmed up).
How does the car run once warmed up now?
