1995 honda accord starts and dies Need help replaced distributor main relay and ignition switch help please

 

How long does engine run? seconds, minutes?

Suggest checking fuel pressure. There is a tap on the fuel rail that requires a special fitting to attach fuel pressure gauge.

If pressure is low/disappearing when engine dies, then either fuel pump, fuel pump inlet screen blockage, or fuel filter blockage.

If pressure is good, look for an electrical problem w/ power to the distributor; bad wire, ignition switch, or distributor.

good luck
