no output from my 5 pin ecu

If I am incorrect about how you have it wired, please post the diagram you are using.

A couple quick checks:

1.. THE ECU BOX MUST BE GROUNDED
2..."Hot wire" power to the coil+ with everything connected
3...Disconnect the distributor trigger connector. Take the end leading to the ECU harness and repeatedly tap the bare connector terminal to ground. Each time you do that should give you 1 sharp blue "snap" spark out of the coil wire
