    Is it in the same spot on a 1996 3.1 though?

    There are 2 crank sensors on the 3.1. The 7X sensor is on the back side (firewall side) lower middle of the block. This crank sensor is not as big of a failure as the crank sensor wiring harness from the crank sensor to the ICM. The harness gets coated in oil and shorts out. The 24X sensor is behind the harmonic balancer. I don't think I have ever replaced the sensor behind the balancer.
