The firing order for a 1990 Oldsmobile Cutlass Supreme with a 3.1 liter engine is 1-2-3-4-5-6. When facing the car, the spark plugs are 2, 4, and 6 in the front and 1, 3, and 5 in the back.
looking at the ignition coils from left to right (passenger to drivers side). First coil: 5 2 Second coil: 3 6 Third coil: 4 1
Look at the rear lower section of engine - follow the + battery cable
Oldsmobile Silhouette was created in 1990.
On my 1990 the crank sensor is behind the vibration dampner. I just replaced it last week.Cost $35.00 at Auto Zone. Just be careful because you have to align the veins on the back of the dampner to go in between the grooves of the sensor.
