Question about 1993 Buick LeSabre

2 Answers

Lesabre wont crank

My lesabre just shut off in the middle of the road. Got it home there is no fire to the plugs and the security light stayed on. It would turn over but would not fire. I was told it was the key, got a new one. I was told it was the control module, got a new one. The problem is still there it will turn over but there is no fire to the plugs. Can you help?

Ok here it is. These columns are junk and the wire that reads the resistance of the key brakes inside the column. Go to radio shack and have them measure the resistance of the key and then buy a resistor in that range (about $0.99) then go under the dash and find the real skinny yellow and orange wire coming out of the base of the column cut them and splice your resistor in. Now you car senses that the chip (or the resistor) is in the ignition. If you want to fix it the right way go to a local junk yard and buy a column but you will need to use your old key and ignitiin cylinder.

If there is a chip in your key(little black square) then I would suspect the ignition cylinder. The contacts that pick up the resistance from your key can fail and cause a security issue which shuts down the ignition system. You will have to get a new key cut for your new cylinder with your old VATS code(the reistance in the chip on your old key).

Good Luck
