Nissan Repair: starting problem, crank shaft, leaky injector

Question
I tryed startng my car and have a problem with it. After constanly pressing on the gas while trying to start it for a few minutes it finally starts. It shut's off while driving and will not start for about twenty minutes or longer. I had the spark plugs and crank shaft censor changed but it still takes a while for it to start.

Answer
Charles,

I do not know which Nissan you have or what year.  I would think the cold start is not working.  That would mean the sensor is defective or you could have a leaky injector or two causing flooding when you first start the car.  Email me back with the year and model.
