Does this car have a fuel pump inertia shutoff switch? I'm not sure where
in the circuit the inertia switch is located, before or after the relay, but
if it has been tripped, the fuel pump may not be getting any power to it.

Good luck,

wwith the results you posted the first thing i would do is apply 12v+ to
the gry wire entering fuel pump module and try starting engine.....if it
starts, or at least has reliable fuel pressure, start finding out why
current isnt passing from relay to pump..........gray wire from relay to
pump connector.........
