does a 1994 S-10 with a 4.3 throttle body have a crank sensor and where?

from what i see you don't have a CPS. the ecm uses the distributor to locate the cam/crank.

for "no spark" condition,

all info points to the distributor cap/rotor, ignition components in the distributor, ignition switch, or a bad ecm.

obviously that's barring an open circuit somewhere. bad wire or connector.

Crank sensors are usually located somewhere on the side of the engine block. Not often easy to get at.

it's on the front of the engine below the harmonic balancer, not that hard of a repair job

if you look down behind the harmonic balancer and see weird teeth with a sensor facing the teeth then there it is
