Try reseating the connector on the computer, then check for voltage at the injectors

I would like to add that voltage is only present at the injectors when you press the starter button..........
or the engine is running.

But as your fuel pump is running you probably also got voltage at the injectors....powered from the same relay.
The signal to the injectors is on the ground side.
