up til last night the car was running fine. all of a sudden i turn the car off and the car dont turn on no more. all of my lights work including the radio. so i have my cousins push the car with the car in first gear and clutch in, then i quickly let the clutch out and the car starts. so now im thinking that it might be my battery or posts. so im unscrewing the terminals when all of a sudden a big *** sparks errupts, almost like a fire.(it was pretty big). **** now im thinking that my fuses are fried. i check them and they are ok. i turn the key to the on position and im not throwing a cel no more(before i was). i took my battery to kragen and they said it was good. could i have fried my ecu???.......HELP!!!
