an injector can leak at any time…it just happens, its an engine it slowly breaks down and rubber gaskets(O rings in this case) get old. A leaky injector will cause ur car to be hard on starting. The gas will slowly leak out of the fuel rail and the line if there is lack of pressure.(goes back into the tank). so in turn, when ur starting ur car and u press the gas its pushing the gas through the line faster making it start quicker. Ur car will start when its warm with ease because the injector hasnt had enough time to leak… ---

“rubber gaskets(O rings in this case) get old” dont O rings just seal the injector to the manyfold , and wouldnt a bad O ring just cause a vacume leak? “when ur starting ur car and u press the gas its pushing the gas through the line faster” dosnt pressing the gas just allow the car to get more air so it can get the correct mixture? I dont think it speeds up the pump. Dosnt the O2 sensor only work after it reaches its operating temprature? ---

did your car run good when it did turn on ? And i checked the fuel pressure theirs no significant dropping of pressure
