I can’t open the jagrepair link but I haven’t been able to access the jagrepair site for months now. It just times out.
However, thinking about the initial problem, I am not sure that it could be PATS (security) related because the engine cranks and it’s pretty clear that if there isn’t any fuel pressure the fuel pump isn’t running. So as Rob has suggested, starting at the fuel pump relay is a good place.
You could just replace it but before buying anything I would pull the relay and check, with the ignition switched on, to see that you have around 12 volts between pin 1 and ground. This is the feed that energises the relay and comes from the ignition switch via the inertia switch.
There should also be 12 volts on pin 3 of the relay. If either if these are missing the fuel pump will not run.
There are other reasons why it might not run but this is where I would start. BTW I have used the wiring diagram for a 2000 V8 NA spec car. I know your car is 2002 but I don’t have access to my 2002 electrical guide at present but I doubt there are many differences.
