Ford crown victoria p71: Hey Ron my 05 crown vic p71 won't

Customer Question

Hey Ron my 05 crown vic p71 won't start. I've got no power to the fuel pump my check engine light doesn't come on with my key in on position. I've swapped out my PCM with another 05 vic and nothing so this leads me to believe it's a wiring issues. I need help figuring out which wires are grounds and the power wire for the pcm plus relays and diodes. Whatever it may be that my car wonto start. ( it did run beautiful before this issue)
