If you are going to work on this car.. I suggest that you obtain the Chilton Manual.. sometimes these are available to borrow from your local library.. if not try Rockauto.com and purchase one.
Further I suggest that you take lots of pictures as you disassemble so you can get it back together.

SOURCE: harmonic balancer rubbing on the timing chain cover

The rubber in the balancer has broken down and the inner and outer pieces shift and rub on the cover. You need a new balancer.

SOURCE: subaru loyale wagon replacing the timing belt

Get a proper manual like Haynes (amazon, parts store, Haynes.com).  You should not have to take either main pullel or cam pulley off to change timeing belt,  you DO want a new tensioner and and new idler pulley (if there is one).  Failure to replace these may result in a later failure that wipes out the blet, and possibly the motor (if it is an interference motor).
If you can change the oil pump from working on the front side of the motor, you are either a magician or a contortionist;!) and I need you to help me work on my car;~)    It's pretty rare for an oil pump to go bad before 400K km or 300K miles  ... the bloddy things are in a constant bath of oil!

SOURCE: 2001 Buick LeSabre. How to remove headlight

the bolts you are looking to remove are located on the top of the light housing. It only takes 2 of them to remove the housing. One is about 6 to 8 inches long, and the other one is much shorter than that. Just unscrew and remove them, and pull the housing straight out.

How to locate and change water pump on 2000 buick lesabre, 6 cylinder engine


I assume you have a 3800 V6 motor in that model car. When standing with the hood open on the passenger side of the car, the water pump is located in the center of the engine. The pulley will have four small (8mm) bolts. To remove: Loosen the 4 bolts on water pump pulley.
Use 13mm socket wrench on tensioner pully to rotate and pull tension off of serpentine drive belt. Take belt off of tensioner and water pump pulleys, bend back out of the way. Finish removing water pump pulley bolts and remove pully. Remove water pump bolts (there are several of 2 different sizes, 10mm and 13mm) . Remove old pump by prying gently around the pump rim to break the gasket's seal, or tap shaft with a rubber hammer. Remove all signs of gasket material on engine mating surface with a scraper and then some fine sandpaper (1000 grit wet/dry) or steel wool. Use high-tack sealant to mate gasket to new water pump, allow to set to a few minutes. Use high-tack again on engine mating surface, allow to set a few minutes, then put water pump to engine using the small bolts tightening them finger tight. Put a small amount of black RTV sealant on larger, long bolt ends about 1/2 " of threads covered. Insert longer/larger bolts and tighten finger tight. Tighten all bolts to firm hand tight using a criss-cross pattern starting in the center top to bottom, then side to side.Do not overtighten, as damage to your new pump or striping thread holes out will result. Allow assembly to set 1/2 hour for sealants to cure. Install pump pulley. Install drive belt. Refill coolant level. Start engine, allow to warm up and check for leaks. Done! :)

sounds like you have a severe vacuum leak, causing a lean condition. The car runs for a short period because of the rich mixture the computer provides for cold start-up.

I have a 1990 buick lesabre that wont start


Timing chains do not go bad on a 3800. The old 3.8 b engines did. Try a crank sensor. My timing set in my 3800 has 293500.00 miles on it.
