Looking for wiring diagram or information for the injectors.
Specifically, the colors and pin out at the EMC for cylinder 1.
I believe I have an open on the wire. Possible broken ground wire or bad connector.

Thanks in advance!

Welcome to the forum. The power to the fuel injectors comes from the 20A F/P-INJ fuse in the I/P fuse block and then through the FUEL PUMP relay in the underhood fuse block. The PCM energizes the relay to turn on the fuel pump and ready the injectors on the hot side (terminal A, GRY wire, all of them). The PCM then drives (grounds) the other terminal on each fuel injector to sequence the fuel in:

PCM connector C1, terminal 75, BLK wire, INJ 1 DRV to fuel injector 1
PCM connector C1, terminal 76, LT GRN/BLK wire, INJ 2 DRV to fuel injector 2
PCM connector C2, terminal 76, PNK/BLK wire, INJ 3 DRV to fuel injector 3
PCM connector C2, terminal 75, LT BLU/BLK wire, INJ 4 DRV to fuel injector 4

Thank you very much. As soon as this weather breaks I can get out there and fix this now. That was even more helpful than I had hoped.

You're quite welcome. Do let us know how it turns out when you get a chance.

Is that a question or are you a lawyer?
