1993 Geo Tracker

[fixkick]

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 )?
