Only the drivers side bank is firing. I used a noid light to find the passenger side isn't firing the injectors. The pink wire to all of them that supplies 12v doesn't have power. I was told there was a crimped piece that connects all the fuel injectors together and that's what supplies the voltage to them. Then the computer flashes a ground signal to them sequentially to make the open and spray fuel. The crimped part has become disconnected is what I'm thinking. I need to find where the pink wires run to and run a new wire. Anyone know where I can get a wiring diagram that'll show the fuel injector wiring?

You check the fuse? If I remember inj1 and inj 2 have separate fuses. but you can find wiring here. https://www.gmupfitter.com/
