Ground issues are notorious on these cars.. Ground post at cold air intake, engine ground below right valve cover, power steering ground, especially if they are daily drivers or if they have been modified and you didn't do the work. Batteries also check under start load should be around 11 volts but not below, be sure to check run voltage at the battery as it should be 14.2 to .7, if its a flooded battery check the cells and top off with distilled if needed.
