The car turns over but wont run. If I keep trying to start it eventually it will run but only runs for a second then it dies. I replaced fuel pump and fuel filter, new crankshaft sensor, put new plugs and wires along with a new coils and (ICM), (TPS), (MAS), (IAC). After all that the car still hard to start is there something I am missing? Could it be the low oil sensor on the bottom of the oil pan?

Is your security light on with the key in the run position? Also does it ever start and run? Have you checked for codes in the computer yet?

Yes, if I hold the gas pedal all the way it will run but soon I let off it dies. If I keep the pedal push down when it running it bog down like it cannot breath and chokes its self.
