What happened to the old ignition distributor of dual-fuel Pu Sang taxi? It was hard at first.

This is the distributor drive shaft. Replace the distributor drive shaft first, and then try to replace it with an old distributor. If it can start and work normally, it is the distributor drive shaft. Components that may fail after cold car ventilation, such as spark plug, engine temperature sensor, throttle volume carbon and so on. First of all, the hot car must check the high voltage and ignition head. If there is no problem, check the ignition sensor. If there is no problem, check the distributor.
