no output from my 5 pin ecu

Which EZ Wire kit did you use? The ones I've seen are pretty generic, based on GM components.
That said, it depends on how you wired it- most aftermarket harnesses and schematics for Mopars are based on 4 pin ECUs. Re-check the diagram you used- four or five wires into the ECU plug? A 4 pin ECU will work in a 5 pin harness, but a 5 pin ECU will not work in a 4 pin harness.
