HI Jali, it could be a number of things. The coil could be faulty, there could be a wiring fault, the distributor might be faulty, there could be a poor earth somewhere, the HT leads could be faulty... you'll need to check through each part of the system and work out which item is faulty.
Thank you i changed that electronic distributor with a points distributor but the car start when I kickstart sound is very bad and no power and backfire
