Injectors not firing!
So I got an 86 FC with a blown motor (and a truck load of spare parts) for $200.
Swapped in one with good compression from a running car.
Everything is in, the car has spark and great compression, fuel is getting to the rail the pump is strong.
There is power to the ECU and power at the injectors. The ECU just isnt switching on the ground (firing the injector)
I've bench tested the injectors, they operate correctly.
I've tried a second ecu, same deal.
Not sure where to go from here. Where does the ECU ground the Injectors too?
Also is there a pin out diag? I'd like to trace the injectors back to the ECU
thanks guy

Also there are some extra connectors around... cant see where the go
A green one wire behind the alternator?
Black connector by the ECU from the BODY harness
Connector (a ground?) looks like its comes off the fuel filter or fuel filter area.
thanks
