Question about 1992 Buick LeSabre

1 Answer

1992 3.8l buick lesabre keeps dying when the temp. outside is hot

The car dyes as if someone turned off the ignition key only when it is hot outside no matter how fast or slow the car is moving or it will not start after you turn it off. If I wait 5 minutes the car will start right up until then it will just turn over and not even try to start. In the winter it never died once. I have replaced the fuel pump, fuel lines, fuel filter, fuel strainer, electronic control module, all 3 coils, spark plug wires and plugs, thermostat, and temperature sensor plug. Could a bad catalatic converter cause this problem? I am baffled and any advice I am willing to try at this point.

this issue sounds like u have a bad ignition control module,located directly under ur coilpak. thats wat they do wen they get hot aftr driving a while, shut off while driving(u must b loosing spark to ur plugs)an restarting wen cooled off. one way to check this for urself would b to purchase a spark checker at autozone or pepboys fairly inexpensive, an wen ur car dies, open the hood remove one sparkplug wire install tester between plug an wire, or wire an a good ground an have someone crank engine while u look at the tester bulb,if it lights up an pulses uspark is good,if it doesnt lite up at all while cranking engine ur spark is gone an thats ur problem possibly crank a sensor or the ignition module we mentioned earlier. try mounting the spark checker before the engine dies so u know wat a good spark will look like on that checker..... hope this helps good luck

the security ignition key reader is at fault. A chip is embedded under the keys plastic head. If the module can not read the key no longer the engine will die out after starting.

Sounds to me like you have a leak leak somewhere. They can put a dye in the lines to find out where the leak is, Then have that fixed and get it recharged again. Its an expensive procedure though. I hope this helped

the neutral switch is to prevent the starter from engaging if not in park or neutral - try just bumping the key switch without holding it - the key lock or ignition switch could be keeping power on starter or the starter solenoid could be keeping the starter engaged someone would have to be under the car listening or touching the starter to see this or measuring voltage on solenoid wire

Do you have a Chip in the Key? if so that Could be the Problem,Ya see the chip is a resistor and if it looses its ELECTRONIC VALUE in its Case Resistance it wont start to test this Turn the Key in the ON posission then do the Screwdriver thing If it Starts Key is Good and Most Likely the Ignition (SWITCH) is Bad <<ELECTRICAL Side NOY LOCKEST SIDE For More Info Recontact Me

1997 Buick Le Sabre will not start somtimes


My wife has a 96 we had a similar problem. I believe that the connectors on the chip that is in the ignition key are worn out. The manual said that it is a safety feature on the car if someone tries to use a different key in the ignition or tries to punch it, it disables the car for like 3 minutes. We had a spare ignition key and switched to that and haven't had the problem since. Hope that solves your problem.
