Andrew Says: If you have a multimeter check battery voltage. If it's 12.4V or better you have at least a 75% charge. Next do a voltage drop test over the wire that leaves battery and goes to the power distribution box. It's a black box with fuses and relays under the hood. If you don't have close to 0V replace. 3. Andrew Says: try tapping on the starter and haveing some one turn the key if it starts then u have a bad starter if it dont start then it may be the key tumbler Tag: My 2000 buick park avenue wont start. has new battery but cant even jump it off?
