Buick century 3.1 2000 security light staying on car wont crank what can that be


It's the anti-theft system . (SECURITY ) Keeps vehicle from being stolen !
Important: If the wrong ignition key is used in an attempt to start the vehicle, a Data Trouble Code (DTC) will be set and the Body Control Module (BCM) will not send a fuel enable or starter enable message to the Powertrain Control Module (PCM) for three minutes even if the correct ignition is used.
The Pass-Key II?® Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM) dose not identify the use of the correct ignition key to start the vehicle, the (BCM) will communicate a message to the Powertrain Control Module (PCM) which will disable the crank relay and fuel delivery to the engine.
When the (BCM) identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the (BCM) will send a fuel enable and starter enable message to the (PCM) which will allow the vehicle to start.
Your best bet would be have it towed to a qualified repair shop !

When the car is cool it will crank up, but when itget hot it shut off and wont crack backup


Does it crank and wont start, or does it not even crank over when hot? If it still cranks, if the starter cranks the engine over, then check for spark when it won't start. If you have no spark, something in your ignition system may get hot and fail-something like the crank position sensor, or the ignition control module.
Here is how to check for trouble codes on your Lesabre, and the code descriptions:

Ok we changed the ignition module in our 1987 buick century, 2.5 liter and now when you start the car it just dies continuiously but once we get it started it will go but acts like it wants to die at stop...


Did you replace the crank sensor that is bolted to the back of the module? Is it possible that you got two of the plug wires switched. Or maybe 1 of the two coils is bad.

Installing ignition module


Unscrew the ignition coil(s) from on top of the module...(leave plug wires attached)....and set aside noting coil position on module....unplug module and replace with a known working module.If there is grease under old module...transfer it to new module.Replace coil(s) and start her up.
TIP. While you are there,why not also change the crank sensor (if it not new).....it is THE trouble maker on these engines.

96 Buick Century stalls....


I spent endless time on this same problem on my 1992 Wagon. I changed out the computer but no help. It turned out to be the top dead center crank sensor that tells the system when the crank passes TDC. It is a small magnet essentially about the siz of a pencil eraser in the flywheel. it was cracked and occasionally would not "sense" and the car would just quit. troubleshooting was a nightmare because the computer diagnostics on the 1992 are less capable than the 1996 model. Anyway that is a relatively inexpensive fix and easy to know if it worked. Let me know how you solve this.

1987 Buick Century Limited V-6 engine w/ac. Engine cranks but won't start. Instrument panel light shows "Service Engine Soon". Also light shows "Oil Choke". And light shows picture of battery.


I took my car to my mechanic. He did a diagnostic circuit test on the engine and then replaced the distributer ignition module and camshaft and crankshaft position sensors.

1992 Buick Century won't start sometimes but has spark in the plugs.


Faulty cam sensor maybe - it controls the injectors. To diagnose, when you get a non-start, spray a V.small squirt of easy-start(ether) and if it runs a little then you have a fuel issue. The spark timing is controlled by the crankshaft sensor so that can be faulty and cause a mistimed spark but usually you'll get a mis-fire in those cases.
