How many miles on vehicle? Does it have the proper amount of oil in it??
Is the low level light on?? You changed rotor and cleaned distibutor cap but did you check for any brownish dust on the optical sensor?? Does it matter if the engine is cold or at normal operating temp when not starting? Have you changed fuel filter since changing fuel pump?? How did you clean 02 sensor?? The throttle position sensor could be faulty, they are a wear item.
