That year did not have a crank sensor.
the crank sensor is located on the back of the engine aprox. 1 inch above the oil pan. there is one bolt holding it in place, after removing the bolt pull the sensor out installation is reverse
The answer depends on what engine you have.
Crank sensors are always located on the camshafts. The 1989 Pontiac Sunbird crank sensor is located on the head of the engine towards to end of the camshaft.
behind the engine,in front of the transmission, about half way up the side of the block, its very hard to see its near the knock sensor.
depending on what engine you have, 4.3 v-6 or 305 v-8 or if your lucky the 350......chevy never ran a crank sensor on an engine that old. If it wont start, check spark, if you have spark, check fuel.
The oxygen sensor on a 1989 Chevy Celebrity is located in the rear exhaust manifold on top about the center.
If it is a distributorless ignition system, you don't. The timing is all handled by the ecm. It picks up the signal from a crank sensor in the block. It has a reluctor wheel cast in the crank.
Replace your control module.
This car only uses the sensor in the distributor.
