I have a 68 camaro rs... Basically I gave my brother big block riveria a jump and know my car won't start or crank... I checked the battery and the cables, the voltage is good and I cleaned the battery to and replace the starter... what should I do to fix the problem ... Please Help

 

Do you have a full 12 volts to the ignition switch? If so, the switch might be bad. Check to make sure there aren't any blown fuses.

Merry Christmas.
