All Fieros equipped with a distributor (1984 - 1986 4-cyl and 1985 to 1988 V6) have the crank sensor inside the distributor. It may also be known as a distributor pickup or HEI pickup.
Fieros with DIS (1987 to 1988 4 cylinder) have a crank sensor on the back side (engine side) of the ignition module extending into the engine block. The ignition module is the flat base that the ignition coils are attached to.
this should help you out! Brian
it's on the side of the throttle body(3 prong plug)

where is the coolant temperature sensor locate
it sits on the intake manifold on the right side looking at the car from the rear..its a black plastic looking box, attached directly to the intake.
Standing straight up in the drivers seat.
There is not one
You will see it screwed right in there in the top of the tranny with 2 wires coming off. It's a pretty large sensor so it's fairly obvious. Just run into any AdvanceAuto Parts store and check out the Haynes manual for a Fiero. It's in there. You should a manual already if you own a Fiero or you should get one! ;-)
I don't think it has a IAT sensor, but it does have a temperature vacuum switch to work the heated air door.
