The crank sensor is located behind the crank pulley on the 3.8 liter. The crank pulley must first be removed. A 15/16" socket, three very long 8 x 1.0 bolts (pretty sure that is the size, some large washers, and a crank pulley pulley will be required.

With the crank pulley removed mark the bracket where the old crank sensor is located so that the new sensor can be placed in exactly the same position. Failure to do this will result in the new sensor and/or the crank pulley being severely damaged.

Then it's as simple as removing the old sensors and installing the new one.

Good luck and let me know if you have any questions.

How do i replace a crank shaft sensor on a 2001 buick lesabre

The crankshaft sensor is located behind the harmonic balancer. There is a special tool you can rent/loan from your local auto parts store in order to remove the harmonic balancer. Once it is off 2 bolt hold the crankshaft position sensor in place. Note there could be many other factors causing your engine to stall or not restart; but those crank sensors do tend to go out on those engines.

94 buick lesabre 3800 engine, stalls after 10 mile drive and will not start till cools. replaced TPS, Fuel pumpand filter, cam sensor, crank sensor, and ignition control module.

next time it won't run after it heats up, spray or pour water in crank sensor and see if it will start. I have seen new crank sensors go bad.

1990 Buick Lesabre keeps stalling

Check ecm for part number 1228253. If it has this number in it replace it with a 16198264. Gm had trouble with that ecm for a cutting off problem. Mine would stall driving down the road and when I would put it neutral it would start back up and not have any trouble for the rest of the day. You must set the tps with a volt meter or scan tool.
