You can check the battery connector. Make sure they are not corroded; and see if there isn't any melting on it; sometimes it will startup but drive rough, make sure the the connection is tight. Also I think platinum spark plugs come standard on some Buicks, which have a very small electrode and a little gunk will cause them to misfire; I would swapped them for a set of old champion copper plus spark plugs and a new set of spark plug wires.
