Question about 1997 Buick LeSabre
Car battery has been checked, replaced starter all lights and switches work...but when the ignition switch is turned on position it will not start, it makes no sound just nothing...does anyone know what problem may be?
Connect a voltmeter to the battery while trying to crank the engine. Is there a drop in voltage or does it stay at ~12v? If the battery voltage dropped two or more volts while trying to start there is either not enough current to the starter from the battery or the starter might be bad. Not uncommon to get a bad starter out of the box. But if there is no change in voltage level nothing is loading the battery which suggests there is no power to the starter solenoid. Now you are going to need to get to the starter solenoid and see if you have power on the ignition wire while again trying to crank the engine. If there is no power the easiest thing to check is the ignition fuse. If the ignition fuse is okay then you have an open circuit somewhere. Does your ignition key have a resistor built into the shank of the key or is it just a standard key? If yes, sometimes the anti-theft wire harness running through the columb can fatigue over time and break. When this happens your anti-theft system will not close the ignition circuit to provide power to the starter solenoid courtesy of the body control module (BCM). On the other hand if you don't have anti-theft you might just have a bad ignition switch on the steering column.

Hi, I'd be willing to bet that the starter is bad or the battery is. If you can swap a battery from another car to test your car out. if the good battery does the same thing then you know the starter is bad. Good luck.

Sounds like a wire is disconnected at the starter motor.
