No spark after refit

Hi guys, i need your help.

Just getting to the finish line after my engine referb, all back in with oil and fuel flowing. I've recently attached the coil and i'm getting no spark.

I think its some ECU problem as i have bench tested the coil and it works fine. Anyone else had this trouble??

I have also checked that i have voltage at the 3 pin connector situated on the distributor.

What about ignition amplifier. The 7 pin located in scuttle? Make sure it's plugged in ok.. just guessing but worth a try

Can anyone explain how i can get a spark by bypassing the 'ignition amplifier'?
