The 96 3.1 Acheiva has I think two Crankshaft Position Sensor's
One is located on the left side of the engine just below the plugs (it
is hard to get to.
then the other one is located in the front of the engine just to the lower
right corner behind the harmonic balancer. ( must remove harmonic balancer).
the one on the back of engine can be reached from the passenger side of the car by removing the wheel and reaching back to the block.
it takes a 10mm
