    First you need to get an Ohm meter. Then take the ohm meter and measure
    the resistance of the pellet in your key. Write down the resistance you
    need, then go to Radio Shack or somewhere else that sells resistors.
    Buy the combination of resistors you need to match the resistance of
    your key. When you have it right resistance with in 5% tolerance, then
    remove the lower cover of your dash below the steering column. Locate
    the orange cable coming out of the steering column. Slice open the
    cable it should contain two small white wires. Cut the two wires, and
    splice in the resistor on the side that goes into the dash. Then tape
    up your resistors and zip tie them out of the way. That's it, the car
    will think it has the right key in all the time. The reason you haft to
    do this is because the contacts go bad in the ignition lock cylinder
    and then it doesn't send the right resistance. The alternative to all
    of this is replacing the lock cylinder and having it rekeyed with
    another key with the same resistance as your old key.

99buick LeSabre fuel pump don't work when turn key relays good fuses good


This may be related to the antitheft system. The system is known for turning off the starter and/or injectors when it fails. Normally when the injectors are turned off, the car will run for a second or two, and then stall. When it's the security locked out starter, you won't even hear a click when you turn the key. Is there a light on the dash that says SECURITY or a picture of a car with a lock through it? This is a common problem worth looking into. http://www.diy-gm-security.com/

My 93 buick lesabre security light will stay on and i cant start my car til its off


The security system (VATS/PassKey) is having problems, it's typical on those cars/years. When the TDM starts failing, it will do it gradually and the car will begin to randomly don't start like yours is doing now and then gets worse with time up to a point that it won't start anymore. It's been a nightmare for us. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my 94 Park Avenue that has the same security system.

I have a 93 Lesabre the we can't find the flasher for the turn signals help where is it


If the lights only come on but dont flash, activate your emergency flasher with the turn signal off. Take a walk around the car and see that all 4 bulbs light up. If not replace the faulty bulb before looking to replace the turn signal flasher. The flasher unit is located under the dash on the drivers side of the vehicle. You will have to remove the panel under the dash to get at it.

Car wont turn over


these cars have a antitheft system that will shut down fuel and crank. be sure to check to see if after the car ignition is on for 30 seconds and look to see if there is a security light on in the dash. if so then turn to crank if security light flashes your problem is that the chip in your key is not being transfered to the security module, so starter will not work. you will have to replace the pickup in the cylinder or bypass the security with proper resister
