Show a P0230 code. Cranks great, no start. No power to fuel pump fuse. I do have power to fuel pump relay, but none to the fuse. Fuses are good. Swapped out relays and still cranked but no start.
Also shows a P1682 code. Changed out ignition switch but no change.

If there is no power from the fuel pump fuse and there is power to the relay, that good, power to the relay comes from the ECM, Pin 30 is the power to the fuse when the relay close, You might just have to test it with the fuel pump module disconnected, these are popular condition where the connection the the fuel pump corrodes away.
