My old Grand Prix (2002 GP GT 178k) has been sitting for 5-6 months after an accident I finally got around to putting a new battery in it a few days ago and it fired right up. Took it for a ride today, loaded some bikes on the bike rack and took it to the park no problem. After riding we went to fire the car up and just a single click, no start, nothing. Lights work, radio runs, windows work just fine so it seem the battery is good. Tried to jump it, let it sit with jumper cables to a Jeep for 20 minutes, same result. Single click. Checked the ignition fuses, no problems there. Starter?
