1995 Park Avenue Stalls Hot and Have to Wait To Start


1995 Buick Park Avenue. 3.8 V6.
2 problems. Driving a car home left to me in a will. The car just quits. Let it sit for a while and it will run again for a while. It seems when it warms up it just dies and won't restart until it sits for a while. (crank sensor?).....MAIN PROBLEM >.....The horn honks and the lights flash and the car won't start.(delco-loc / theftloc?)..Is there a way to wire around or to completely disable this option? I'm going to give this car to my wife. She goes to work at 5am and drives 7 miles to work.

A  small country road with no place to pull off if the car dies. We don't need the anti theft feature's AT ALL. But she doe's use the radio. Can this be done without it affecting the computer? If so, how?.....PLEASE HELP.

Answer: Yes, this does sound like a crank position sensor problem. It is located behind the crank pulley. You can pour water on it after it is hot and stalls and won't restart. This will usually cause a crank position sensor to allow the car to start- since it is cooled off. Or at least shorten the time you have to wait to be able to start it again. Also can use a long extension and tap on the sensor to try to get it to stall. Be very careful not to let the extension hit the pulley with the engine running.

Horn honking and flashing would have nothing to do with a Passlock or Theftlock system. They do not use the horn. These systems would cause a no start and a flashing security or theft light on the dash. You may be a problem with a factory alarm (Blue Remote), or a non-factory alarm.


Buick Won;t Go Into Gear

Question: My Buick Lesabre car starts fine, but wont go into gear for a few minutes....and once it do, it drives fine... please HELP.

Answer: This could be caused by any number of internal transmission problems. A sticking valve in the valve body, a torn seal in a servo piston, a blown channel plate gasket, etc. I would first have the fluid flushed and filter changed. With the pan off, you would then get an idea of something failing if there is dirt in the pan. If that does not help, you will need to have a trans tech check it out. Depending on the year and mileage, it may be time for an overhaul.

    I have a 1995 Buick Lesabre that just stops running while driving it and won't start until it cools off. Somtimes when I drive it somwhere and shut it off and try to restart it it won't start until it cools off also.This doesn't happen all the time,just sometimes. I've had to walk home to many times. Any help would be greatly appreciated!

    <br />Common for a crank sensor to do this. You would need to check for spark and fuel pressure when it is acting up to be certain.
