Truck runs when gas poured in the tbi. Can hear injectors pulsing. Have plenty of fuel pressure to the tbi but nothing out the injectors or the return line.

What is the fuel pressure?
Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
