Where is the 1997 buick lesabre ignition switch located

The crank sensor should be on the passenger side of the engine. It probably won't be visible without first removing the power steering reservoir, and possibly other items on that side of the engine. It is located down below near the waterpump pulley.

It is part of the range selector switch on the transmission.
Get a wiring diagram if the trans wiring and it is very to follow to determine if it is working or not

Does the security light come on when this happens? You may have a loose connection in the antitheft system. Here is a link about the security

Hope helps (remember to rate this answer).

If you have this Gage problem with the ignition switch off the problem is with the instrument cluster. The oil pressure sending unit is right above the oil filter on the oil filter housing adapter

LeSabre has theft deterrent system. If you have ever seen a theft lamp in the dash the key is special. Don't replace the lock cylinder.
The dealer can punch an ignition key for you. Take the title and registration to the parts dept with your id they should be able to help. Call dealer and ask how much for service. Check pricing at local locksmith. Sometimes the local guy needs the business and will give a better price. If this helps please rate my help. Have a better day

you either could have a bad ignition switch or your ignition switch out of adjustment/loose causing not being in correct location

Spray the beejesuz out of the inside of the tumbler/keyhole with WD40...replace the key and try again...Otherwise an ignition assmbly might be available through a junkyard?
good Luck

It is on the left side of the steering column bolted to the ignition switch. You need to remove the lower dash panel and it is held on with one nut and one bolt
