Fuel Injection Computer - Pin 1
Hey Kingspoint - The small internal Distributor Pick-Up Coil (Green Wire - Out) provides a Pulsed (Square Wave) Signal to 4 components needed for a L-Jet 928.
1 - Fuel Injection Computer Connector -
2 - Ignition Unit -
3 - Fuel Pump Control Relay -
4 - Tachometer -
As the Fuel Injection Computer receives the pulsed signal from the Distributor (In on Pin # 1) - the ECU sends out timed Ground Signals to the 8 injectors - Triggering them in pairs.
With the Spark Plugs firing - then the Green Wire is correctly sending the Pulsed Square Wave from the Distributor to the Ignition Unit. With the Fuel Pump Relay supplying +12 volt power to the fuel pump and the Fuel Pump is running - then the Distributor pulse is reaching the Fuel Pump Relay. With +B 12 volt power to the Injectors then all that is missing is their Ground Signals.
Perhaps the Distributor Pulse is NOT reaching Pin # 1 of the Fuel Injection Computer.
Good Luck Michael
