is this a 2door, (wiring varies by door count so...)
there are many fuses that run EFI.
IG-coil
and FI.

so you have spark and test fuel runs.
does car start with gas cap removed (wrong gas caps fail here)?
on some older 8v engines, you can hear the pump run for 3 seconds key on. old pumps make lots of noise.

now the wiring.
does the CEL lamp glow key ON? (cluster lamp called CEL check engine light) if yes the ECU has power.

seen here.

if the pump is dead.
check the fuel pump wire. behind the left tail light.
remove lamp. housing look inside car body there.
see that large pink wire there?, at the large connector. its must read 12vdc cranking.
if 2 doors, see the black wire screwed to body of car there, in side housing of body.
that is pump ground, (not rusty )?

the pump ground is here G402 (2 door only.

check for 12vdc on the pink wire. if pump sounds dead.
key on, 3 times, with 2nd person at gas filler neck listening. buzzzzzzz , buz for 3 second each key on? y/n
if no check voltage on pink wire.
if yes, check pump pressure. per below 34psi typ.
