my s13 sr20 was running fine then i left the door half way open then the battery died and i left it sit for a week, then i went to put a jump box on it and i was eatting shit and put it on backwards. now it doesnt have spark i tested all the coils they are all good and it is getting power and ground but no pulse. i think the CAS, i dont know if it controls injector pulse cuz it does have injector pulse and everything in the car works fine and i checked all fuses.
