Hi Brian
As the engine runs I am assuming you have battery voltage to all of the injectors? The injectors are all supplied via a ecu controlled relay and switched by ecu pins 10 and 20.
There is some info on this system in Autodata FI book 1 and also in Mototek bulletins 50 & 51. Let me know if you need any more info.hth
