Hi I finished swapping a 2007 sti into a GC8 and every wire is plug and play except the fuel pump harness. Everything works as it should. (I spliced the fuel pump harness myself-I can hear it prime properly and gas gauge works, but didn’t use all the wires from the harness) Except the gas isn’t reaching the motor. I’m thinking of replacing the assembly/pump in hopes of it getting gas.

This is the only thing holding me back from starting the car and everything is together so I’d rather not have to go back to swap the tanks and harnesses if I don’t have to.

Or if anyone knows which wire is what for the 6 pin connector to fuel pump on an 07 sti that would also be great.

Any help is appreciated thanks :)

That code is most likely because the fuel tank sensors arent communicating with the ECU. You'd have to figure out the wiring diagrams and wire it properly or delete the code with a tactrix cable.
