It is usually located either on the left or right side of the engine block, just above the oil pan. If you have a 2.8 or 3.1 it is on the side of the engine closest to the firewall. It will be almost directly under the middle spark plug right under the exhaust manifold.

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.

The 1989 Pontiac Firebird Formula map sensor is located behind the dashboard. The map sensor will be on the drivers side.
