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.
Because its a 1988 Buick LeSabre
If you lights do not dim when turning key, then probably your starter.

To reset the computer codes on a 2001 Buick LeSabre, you can disconnect the negative battery cable and leave it off for about 15 minutes. This will clear the memory and reset the computer. After reconnecting the cable, start the vehicle to see if the check engine light is off. If the light persists, it may indicate an ongoing issue that needs to be addressed.
Start at the battery. Remove and clean all connections. If the battery is over 3 years old you probably need to replace it. Can also be a starter going bad.
To replace the wiper motor on a 2000 Buick LeSabre, start by disconnecting the negative battery cable to ensure safety. Remove the wiper arms by loosening the nuts at their bases, then take off the cowl cover to access the motor. Unplug the electrical connector from the wiper motor, unbolt the motor from its mount, and replace it with the new unit. Finally, reassemble the cowl, reattach the wiper arms, and reconnect the battery.
I also have the same issue with my 1995 Buick Lesabre. It started happening when I overcharged the battery and now the horn goes off at 2am, 6am, and all hours. I have had to disconnect it at both horns under the hood.
