Well I have a obd2 GSR swapped Eg stock motor, stock everything except dc headers and intake, I was driving on the highway then it just decided to turn off, tried turning it on didnt happen, called my bro to jump start me all it did was crank, tried again without cables and battery was drained real fast, Im guessing its the battery, any suggestions?

 

try checking your dizzy. maybe the coil went bad. get a spare spark plug and pull one of the spark plug wires out. stick the spark plug and hold it or set it down on the valve cover. have one of your friends crank the car and watch the spark plug and see if you got a spark. if u see no spark then your coil/cap/ or rotor went bad. OR you might have a bad dizzy.
