Now have ordered wiring diagram so I can trace the wiring. It appears that the PCM controls the power to the fuel pump so something is stopping it from supplying power to the fuel pump

No I did not I unplugged the horn I still hear the ding dong for about 10 minutes

The only thing I can think it's the BCM and I'm not going to put that much money into it it's annoying for 10 minutes I'll just live with it I guess

What odb2 scanner do you have? You’ll want one that is capable of monitoring live data, that way you can see what the pids are. One thing you can do that won’t cost you any money, just some time, is check all the bcm connectors/pins for corrosion.
