This is a manual trans, in case that helps sorting ideas.
That fan you hear might be the secondary air injection pump, it is electric and runs only below a certain temperature when the car is started
From the service manual
AIR INJECTION 25 - 31
-
Air is allowed to enter the exhaust when the PCM simultaneously
actuates the air pump relay, air pump (1), and air
pump switchover solenoid (4) after engine startup for up to 2
1/2 minutes. The following conditions must also be met in
order for the system to become active:
² Coolant temperature >10°C (50°F) but <60°C (140°F)
² Engine speed <3000 rpm
² Throttle valve not wide open
After an actuation, the air injection system will remain deactivated
until the coolant temperature drops from >60°C (140°F)
to <40°C (104°F).
These posts are getting confusing,
1 - does it crank at all? (if not, try catching it in gear to see if it runs, I'd use 2nd or 3rd if you have a place to try)
2 - if so, does it fire briefly, then die? (if so, might be security/theft)
Do you have a fuel pressure tester? You should have pressure with the key on, before you try to start, they are cheap, and I think some places loan/rent them as well. If no fuel pressure, but ignition does turn on the dash and everything else, then you have a starting point, maybe the RCM or something else. Don't forget to test the fuses associated with it.
