Can someone tell me what computer inputs are necessary to fire the fuel injectors?

Hi chaswall, Thank you for the donation. The main input for injectors to fire are the crank and cylinder position sensor signals. The positive wires receives power from PGM-FI main relay and the ECU grounds the circuit with input from the crank and cylinder position sensor in the distributor.
