ok. so im not exactly new to this site but i am new to posting since i usually can find what im looking for. first things first, i just bought an 83 rx-7 gsl for 450 bucks. guy couldnt get spark and gave up on it. now im in the same boat. i have power to the coils but no spark out of the coils. i just checked for ground on the coils during crank and did not get any. what could be causing this? Thanks in advance!
