What is the location of the crank sensor on a 1991 Buick Regal?

Answer 1

If your standing on Passenger side under hood it is under the harmonic balancer on the right side of engine. Im not for sure but i think you have to remove the balancer to get to it. If you look on the right side of the balancer you will see the plug it pertrudes out a little bit. That's just the plug the switch is inside there. Im having to replace mine now since I broke it trying to get the Balancer off.

From Todd

The sensor is halfway down the back side of the motor down low between the transmission and the engine

its held in place with a 8mil. bolt and there is so little room to reach in to get it

The easiest way is to find someone with small hands to reach it.

the only other way is to remove the trans

this is a lot of work the latter so try the way i did it first

lots of luck

i replace mine and still no injectors

i will check the computer and the smart module next

Problem was as shorted injector

found it and now its running but got a air intake leak
