Another 2002GTS that will not start... I have a Bosch, 25 months old battery that giving me 13 volts but when I tried to start the car the voltage just drop and it will not turn it over. I tried to jump it with my truck but still will not start. Decided to check all the fuse, fuel pump, relays, etc. and everything was good. Decided to pull the battery out and get it tested in Advance since they are closer. Turned out that the battery was dead although the voltage was good the crank was "zero". And since it still under warranty... I head down to Pepboys and got a replacement.
