Starter seems to be out on 2003 Buick Century- it

It's possible it could be bad...However double check your battery, and your battery cables, and make sure you have enough voltage at the battery..should be atleast 12.6..give a take a few, but no less than 9.6..and if your terminals are not tight, that will cause that to happen also...Goodluck....

Souns like you right but boost the car fisrt,if it goes then, then replace the battery.To ceck to see if it's the starter solenoid cross the two larger posts on the starter and see if it will spin,if yes then replace the solenoid,if mo replace the whole starter or have it repaired.

Have battery tested first, if you have a good battery, replacing the battery is a fairly simple task with good jack, jack stands, and a few metric sockets and wrenches.
