The 2006 Buick Lucerne comes with an automatic transmission in a V-6 or V-8. JD Power rates it at a 3.5 for mechanical quality, which is just above average. If your Lucerne won't start, you will want to go through a series of steps to try to determine the problem. There are several reasons why a car engine won't start. Some of them are easy to fix, and some are not.
Turn the key and see if the check engine light comes on. If the check engine light comes on, it means the computer controlling the engine is active. If the engine light does not come on, there may be a problem with the computer such as a broken fuse.
Add fuel if you are low. A car won't start if it has no fuel. Cars.com points out that it is possible that a fuel gauge could be broken. You might think your Lucerne has fuel, but it may be empty.
Turn the ignition on, and then turn the windshield wipers on. If the windshield wipers are running slowly, the battery may be dying or dead. Cars.com suggests you also check the dashboard lights. If the light is dim the battery may be depleted. You can recharge the battery by jump-starting the Lucerne and letting the engine run for a few hours.
Listen for unusual noises. According to Cars.com, heavy knocking may suggest engine problems, while a whistling sound may mean a belt has come loose.
Take the Lucerne to a mechanic. If you cannot fix the problem by jump-starting the car or adding fuel, then a mechanic may need to fix the car.
