Unfortunately, throwing parts at the car will not fix it
First off, turn your key from off to run but do not start (radio off!). Do you hear a whir sound coming from the trunk area?
If so, there is voltage to the pump. Hook up a fuel pressure gauge and check the pressure after2 off->run ignition cycles.
If not, first thing to check is the fuse! Then check the inertia switch.
If no whir, pull the fuel pump relay and jump the #87 and #30 pins in the socket for just a moment with some wire. Is it whirring now? If so the problem is between the relay and PCM, whether wiring, loose socket, etc.
If nothing, check for voltage at the relay socket #30 pin. No voltage? Problem between socket and battery junction box.
There is B+? leave the terminals jumped and check for voltage at inertia switch connecto. If no voltage problem between relay and inertia switch. If B+ into the switch but none out it (the switch) is faulty (rare) or the connection is bad
If there is B+ in/out the inertia switch (backprobe connector with it plugged in) pull the fuel pump connector above the rear crossmember (you need to pop it out with a long screwdriver then disconnect) - jump the relay terminals again and check for voltage at the pump connector. If none problem between inertia switch and pump. If there is B+ wiring issue between connector and pump (check wiring on fuel pump hanger)
