Hi:
If there is no injector pulse, first confirm the fuses in the attached pic are good. Next, confirm that EFI relays 1 and 2 are getting power.
The signal to fire the injectors comes from the ECM, so make sure the connector is tight, clean, and not corroded. If it looks good, you will need to confirm a signal from it is present. If there is no signal and everything is in good condition, the ECM itself will need tested.
Let me know what you find.
