i got a 92 civic and the first time i started the car it ran for about 5min and then died. re did the timing now the timing is dead on put in a brand new coil and it started right up and i let it idle for about 15 min while checking things out it sounded like it was running very smoothly shut the car off then went outside about 20 min later and tried starting the car again but this time no spark. checked for spark with a screwdriver in the plug wire but nothing what would make my coil in my dizzy keep going out?
