Thanks for sharing this information my car will start in the morning then I get to work and if I got to move it to repairq it it will start and then die right away
@danielworden4695 That almost sounds like a Fuel pressure Regulator Problem. Here me out When the engine is cold it requires more fuel to run. When the engine is at operating temperature needs less fuel to run. When your fuel pressure regulator goes bad the diaphragm inside of it allows to pass by and be sucked in from the Vacuum Tube that is connected to the Pressure Regulator. So basically of a morning that extra fuel will allow it to start fine. But after you warm the engine That extra fuel floods the engine and it won't start There are multiple things it can be But this came to mind
Your probably wouldn't hurt especially the intake gaskets as there notorious for going out. I don't think this one has plastic hoses. There rubber and actually connect to alternator bracket. Coolant flows thru bracket and 2 90 degree elbows into block.
@@sartingarage8045 I'm nothing more than a TH-cam mechanic and this engine and car is a dream to work on. The starter is located underneath with nothing in the way, the alternator is super easily accessible, there's tons of room in the engine area, there's an access plate in the trunk to replace the fuel pump. One of my theories is that they planned on making a V8 Lesabre (possibly Northstar) and that why there's so much room in the engine. We live in Florida and we bought this car from a retirement trailer park. It has absolutely no rust! Most of the stuff we've fixed on it is from age and dry rot. On a side note, Buick, Lesabre, Century and Park Avenue of that era are basically the same car with different trim packages. The Century might have come with a 3.6 though. The Park Avenue Ultra came with a Supercharger.
Thanks for the video enjoyed watching it.
Great video! My daughter has a 2000 Lesabre and she loves it.

It also probably needs intake manifold gaskets and replace those plastic coolant tubes next to alternator.
