My 90 lesabre did the same thing. When it cut off after driving I sprayed water on the crank sensor and it started right back up. A buick mechanic told me to do this and this is how I found out the crank sensor was bad!

Possibly the crank case oil sensor. Had the same symptoms on a Buick LeSabre '91

It's located on the block, just above the water pump

yes that bolt is keep the balencer mounted to the crank shaft

Check Autozone.com or another such sight They might have a picture. They did for the same part for my 91 lesabre. (Which may very well be the exact same part)

probably damaged the crank sensor, or the tangs on the harmonic balancer

User Avatar

its behind the harmonic balancer attached by two bolts but you must first take off the balancer to get to it

check the wiring goig to the crank sensors and check and see if you can adjust the gap on the outside sensor maybe its not properly connected

The Crank sensor in my 91 LeSarre Limited is behind the Harmonic balancer pulley....there are fins on the back of the pulley that line up with the sensor.

On a 2004 Buick Lesabre it could be a faulty (MAP) Sensor, Manifold Absolute Pressure Sensor. The car could start, run and drive, and when you shut it off it will crank but not start up again.

the oil filter is on the left hand side of the engine (if you are looking at it from the front of the car with the hood open), behind the crank pulley.

Remove belt, balancer bolt and get a balancer puller to remove the balancer. Unbolt and unplug sensor to replace it. An air impact wrench that is strong will get the bolt loose.

You put a new crank sensor in your 92 buick and now its like its out of time?

User Avatar

It depends on if it won't "crank" or wont't "start" if it worn't crank make sure your battery terminals are clean and tight if it still won't crank check the wiring if it looks ok suspect the starter.if it won't start it could be a fuel pump fouled spark plugs faulty ignition module faulty crank sensor or out of time. hope this helps.

could be the crank sensor, the go out. the have a reputation for that.

When the security light is on the starter will not engage. You must wait a few minutes for the light to turn off before attempting to start car again, this is to help prevent theft. Ensure the contacts on the black chip on the key are clean and that the chip is centered in the key.
