I just replaced the head gaskets on my2003 Buick Century Custom 3100 3.1 v6 & now I can't get it to start ? Timing ? How to adjust?
Go back to basics. What EXACTLY is it doing when you turn the key? Is it dead? Sluggish? Just spinning? Trying but stalling? Starting but won't tick over? All clues to the issue your having.
Are you getting any warning lights? Have you scanned it for OBD Trouble Codes? There's also that silly, obvious one that gets everyone eventually, Is there fuel in the tank? Yup! I've done it!
Recheck EVERYTHING you did. Sometimes it's simple case of you missed a wire or a pipe when you put everything back together. Turn the engine by hand to Top Dead Centre on cylinder 1 and recheck ALL your timing marks. Then check your firing order to make sure the plug wires are ordered correctly.

No spark on 2005 Buick LeSabre 3.8L engine
Did you have it on a scanner or just replaced parts? A scanner can read what the sensors are doing. You may have a bad wire connection that is not allowing the sensors to work.
2005 Buick Century whining on starting, whining increases climbing hills.
Try taking the belt off and starting the engine. If it is something in the accesory system, the whine will go away without the belt. If it is still there you know it is something in the engine. If it does go away you can then spin and feel the bearings in the tensioner and idler puleys to find the source of your noise.

2006 buick lucerne back doors
My friend just had this problem and he reached in and pulled the inside door handle back as far as it would go, and then let it go, allowing it to 'snap' back. For some reason this fixed it. We have no idea why. By doing this on one door, both rear door locks freed up and the rear locks are now working. Before, both rear locks were stuck and you could not open the doors from the inside nor the outside. Not sure why it works, but maybe it will work for you!

My air ride suspension in my 2007 Buick Rainier is not rising but the pump is on I can hear it but it isn't
Check the air lines coming out of the pump and into each airbag at the wheel end. With the pump running listen to all the joints and air lines you can get to. If it is not rising at all it is most likely an air leak that you will be able to hear. Is there a pressure gauge on the dashboard or on the compressor tank itself? Checking this will show if the pump is actually generating enough pressure to fill the tank to feed the airbags.
