Check and test the fuel pump fuse, inertia switch and the fuel pump relay

I checked the fuse it isnt blown I replaced the relay and when I check to see if there is power to the inertia switch, there is no power to it so what do I do

If both fuse 9 and 14 are okay-its either the computer controlled of the relay is defective or open and also the violet and orange wire is open to the inertia switch

The computer control of the relay energizes the coil side of the relay this don't happen-no power to the fuel pump
