Sounds like the starter to me(I assumed you meant won't crank when hot).I have replaced only 1 starter(on my neighbor's Taurus)in the 15 years after quitting the GM dealer tech job 15 years ago.I probably could make a career just changing GM starters and alternators.(I only have Mopars in my driveway!)

SOURCE: 1995 Buick LeSabre won't start when security light comes on.

When my 1994 LaSabre had a problem recognizing the chip in the key (due to the contacts in the lock not working), I managed to bypass the system by locating the two wires (clear tube with two smaller wires in it exiting the steerin column, unlike any other wiring), cutting the cable, and soldering a resistor across the two wires that go to the hidden module thet in turn controlls the starter and sends a signal to the engine computer. Use a resistor of the same resistamce value as in one of the keys for the car (measure resistors with a digital meter). There are a dozen or so values used. You loose the extra protection of the chip, but the fix is low cost.

SOURCE: 1998 Buick Lesabre How do you test the coil packs?

the coils are one integrated block with 3 separate segments. the coil pack is mounted to the ignition module and can be unbolted from each other. one can test the coils from the underside of the coilpack with a dvom. having said that your car should still start if one paired coil fails, it would however miss on one or two cylinders. I would suggest to scan for codes, monitor live sensor data to see if you have a valid crank signal, check fuel pressure and spark voltage

Is your SECURITY light flashing when this happens? If it is, then you most likely need to replace your ignition tumbler. Otherwise the only advice I have is to scan your engine computer and body control module to see if there are any fault codes.

My 1997 Buick LeSabre sometimes won't start right away. I have electric power, windows roll down, air blows etc...I change to my spare set of keys and after about the 3 rd turnover it starts?


you might need to clean your battery terminals first and if that does not work, then go have your starter tested to see if it is the selinoid, that is going bad.

Sounds like you have a bad connection at the battery, the starter or where the negative battery cable connects to the engine. Or you have a very dead battery.
