Really need a little more info. but at first thought sounds like either a cold start sensor if equipped. or a coolant temperature sensor. the cold start sensor squirts fuel directly into the intake upon startup wen the vehicle is cold. the coolant temperature sensor adjust fuel air mixtures based on the temp. of the vehicle. when they go bad they go to default which is usually about 175 degrees. so when the car is cold and the faulty sensor tell the computer that the car is 175 degrees when its not then the computer delivers the wrong fuel air mixture, the mixture as needed when its warm when the car is actually cold and needs a different mixture in order to start more easily.

Have a compression test done to determine the engine condition. With the hard start and oil usage it points to a worn rings and a lower compression pressure than is required.

Hard starts in the morning even though replaced most parts


Check the power to the cold start injector. (it's only going to have fire for a few sec. after the key is turned on). If the fire is good, replace the cold start injector. This injector is activated for a few seconds when the engen temp is low to add a little fuel lower down in the intake and closer to the pistons.
