Welcome to the forum, use a testlite, check voltage circuits at the fuel pump relay. Voltage for load side of relay is hot all the time. Voltage for coil side of relay goes hot when you turn on the key. Pcm grounds coil side of relay to energize, initial prime or engine running.

Brown wire with white tracer is the ground controlled by the pcm, terminal 85, according to my info.
